Long Carbon Fiber In recent years, due to the growing demand for lightweight in various industries around the world (automotive, aerospace, military, building and civil engineering, etc.), and the increasingly strict requirements for the use of environmentally friendly and sustainable materials, the use of fiber reinforced thermoplastic composites in various industries has been increasing. Especially for carbon fiber reinforced composites, there is still a high recycling value after the products are discarded after completing their life cycle, and through effective recycling technology and methods, the cost of carbon fiber reinforced composites can be significantly reduced. The recovery method of fiber reinforced thermoplastic composites is closely related to the shape and forming method of fiber reinforced in resin. Take carbon fiber reinforced thermoplastic composites as an example. The reinforced forms of carbon fiber mainly include short fiber reinforced, long fiber reinforced and continuous fiber reinforced, and the main preparation method is melt forming. For thermoplastic resins with high melting point, such as polyetherimide (PEI) and polyetherether ketone (PEEK), solvent forming can be adopted. Due to the linear molecular structure of thermoplastic resin, it is easy to transform from solid state to liquid state at high temperature. Therefore, thermoplastic composite materials can be recycled by remelting and reshaping method, which is more recyclable than thermosetting resin matrix composite materials. PP-LCF datasheet Application Our materails all can be recycled At present, more and more companies are developing recycling methods for fiber reinforced thermoplastic composites. For example, the 2014 Chevrolet Corvette uses composite materials containing recycled carbon fiber in 21 body panel components, including doors, boot LIDS, side coops and fenders. Ford Motor Company has used recycled long carbon fiber and polypropylene (LCF/PP) composites to replace the original ASA engineering plastic as the rigid part of the A-pillar bracket in its 2018 Explorer sport utility SUV.

PLA plastic Polylactic acid (PLA) fiber is made from starch raw materials such as corn and wheat, converted into lactic acid by fermentation, and then polymerized to obtain PLA, which is made by solution spinning or melt spinning. It is a fiber that completes the natural cycle and has biodegradability. The fiber does not use petroleum and other chemical materials at all, and its waste can be decomposed into carbon dioxide and water under the action of microorganisms in the soil and seawater, so it will not pollute the earth's environment. Since the initial raw material of this fiber is starch, its regeneration cycle is short, about one to two years, and the carbon dioxide it produces can be reduced in the atmosphere by plant photosynthesis. Long carbon fiber reinofrced PLA Carbon Fiber (CF) is an inorganic fiber containing more than 90% carbon. It is made by cracking carbonization of organic fibers under high temperature environment to form carbon main chain mechanism. As a new generation of reinforcing fibers, carbon fiber has excellent mechanical and chemical properties, including: 1) Light weight. Carbon fiber density and magnesium and beryllium is basically equivalent to less than 1/4 of steel, the use of carbon fiber composites as a structural component material can make the structure quality reduction of 30% -40%. 2) High strength and high modulus. The specific strength of carbon fiber is 5 times higher than that of steel and 4 times higher than that of aluminum alloy; the specific modulus is 1.3-12.3 times higher than that of other structural materials. 3) Small coefficient of expansion. Most of the carbon fiber at room temperature coefficient of thermal expansion is negative, the coefficient of thermal expansion under high temperature conditions is small, it is not easy due to high working temperature and expansion and deformation. 4) Good chemical corrosion resistance. In the acid, alkali environment are very stable performance, can be made into various types of chemical corrosion products. 5）Strong fatigue resistance. Its composite materials by stress fatigue millions of cycle test, strength retention rate is still 60%, while 40% of steel, aluminum for 30%, glass fiber reinforced plastic is only 20% -25%. Carbon fiber composites are the re-enforcement of carbon fiber. Although carbon fiber can be used alone and play a specific function, however, it is ultimately a brittle material, only with the combination of matrix materials to form carbon fiber composites, in order to better play the mechanical properties, to carry more load. Long carbon fiber & Short carbon fiber Long carbon fiber (LGF): 6-25mm/ High performance, high cost Short carbon fiber (SCF): less than 6mm/ Low performance, low cost In the composite material made of fibers is sheared or pulled, the fibers are pulled out from the matrix, such a pulling process is conducive to the absorption of energy provided by the loading, the longer the fibers are within a certain length, the greater the absorption of energy, and the more significant its strength. And in the same volume amount, due to the longer the single fiber, the fewer the number of fiber roots, the less stress concentration generated at the fiber end, the more difficult the destruction of the material. From the results of the feedback of practical applications, the various properties of long carbon fiber reinforced thermoplastic composites are more excellent than those of short fibers. ●Will the use of Xiamen LFT-G materials increase the cost? a. The unit cost of the material is slightly higher than aluminum alloy, but the cost/time of secondary metal processing can be saved, which is relatively advantageous overall. b. The unit cost of the material is slightly higher than that of a homogeneous staple fiber reinforced composite material, but LFRT has high dimensional stability, is not easily deformed, and can be assembled after demolding, which saves cooling/pressure retention time for molding and cost/time for fixing fixtures.

Thermoplastic prepreg tape composites What are thermoplastic prepreg tape composites? Composites have three elements 1: Matrix resin, e.g. PP, PA 2: Fiber, such as carbon fiber, glass fiber, and 3: fiber morphology, is one-dimensional, or fabric form, different weaving state has different properties; Prepreg is a combination of resin matrix and reinforcement made by impregnating continuous fibers or fabrics with a resin matrix under strictly controlled conditions, and is an intermediate material in the manufacture of composites. Certain properties of prepregs are carried directly into the composite material and are the basis of the composite material. The properties of the composite material depend largely on the properties of the prepreg. PP-LCF composites Long fibre reinforced thermoplastics, LFT for short, uses PP as the most common base resin, by PA, but also PBT, PPS, SAN and other resins, just for different resins need to use different fibers to achieve better results. In the automotive industry, LFT-PP (Long Fiberglass PP) is used in car hoods, instrument panel frames, battery trays, seat frames, car front-end modules, bumpers, luggage racks, spare tire trays, fenders, fan blades, engine chassis, roof racks, etc.. LCF V& SCF In contrast to LFT, SFT (Short fibre reinforced thermoplastics), the biggest difference in their appearance is the difference in the length of the particles and fibers: SFT Particle length: 1-3 mm Length of reinforcing fibers: 0.2 to 0.6 mm LFT Particle length: 6 to 25 mm Reinforcing fiber length: 6 to 25 mm Applications The earliest and most mature application of LFT-PP is in automotive parts. Due to its excellent performance and cost-effectiveness, LFT-PP is increasingly being used in other fields such as instruments, chemical equipment, power tools, gardening tools and so on. e.g. Replacement of staple fiber PA6-GF30 with LFT PP-GF50 No water absorption, higher dimensional stability No change in mechanical properties due to moisture absorption Related materials                        PA6-LCF                                    PPA-LCF                                    TPU-LCF Frequently asked questions Q.

Throughout the plastics industry, PEEK is widely recognized as a leading high performance polymer (HPP). However, the preferred material in the automotive, aerospace, oil and gas, and medical device industries has long been metal, and PEEK polymers are rapidly changing that mindset. What is the PEEK material PEEK or Polyetheretherketone belongs to the class of polymers known as "aromatic polyketones" (more accurately Polyaryletherketone or PAEK). Research and development of PEEK began in the 1960s, but it wasn't until 1978 that Imperial Chemical Industries (ICI) patented PEEK, and Victrex PEEK polymer was first commercialized in 1981. "Aromatic" usually implies a distinctive or sweet flavor, which may seem like an odd term, but scientists use it to describe certain molecules that contain or consist of a cyclic structure (such as the aryl unit above). Small molecules of this type, such as toluene and naphthalene, have distinctive odors and hence the name. However, PEEK itself, like most thermoplastics, is odorless under normal conditions. Chemically, PEEK is primarily a linear semi-crystalline polymer. P comes from the Greek word "poly" meaning "many", so many EEKs form PEEK. aryl and ketone groups provide stiffness by being somewhat rigid, which means good mechanical properties and a high melting point. The ether group provides a degree of flexibility, while the aryl and ketone groups are chemically inert and thus chemically resistant. The regular structure of the repeating units means that the PEEK molecule can be partially crystallized and the crystallinity provides properties such as wear resistance, creep resistance, fatigue resistance and chemical resistance. The resulting polymer is widely recognized as one of the best performing thermoplastics in the world. Compared to metals, PEEK-like materials are lightweight, easy to mold, corrosion-resistant, and have a fairly high specific strength (strength per weight). Datasheet for reference When high performance is required, PEEK as the polymer of choice offers more than just two or three properties, it offers a wide range of excellent properties including: - High heat resistance Testing has shown that LFT-G's PEEK polymer has a continuous use temperature of 260°C (500°F). This allows for a wide range of applications in hot corrosive environments such as the process industry, oil and gas industry, and the engines and transmissions of countless vehicles.PEEK resists friction and wear in dynamic applications such as thrust washers and seals. - Chemically Inert PEEK resists damage caused by chemically corrosive working environments such as downhole environments in the oil and gas industry, and gears in mechanical and automotive applications. It is resistant to jet fuels, hydraulic fluids, de-icers and pesticides used in the aerospace industry for a wide range of pressures, temperatures and time frames. - Strong mechanical properties PEEK exhibits excellent strength and stiffness over a wide range of temperatures, and the specific strength of PEEK-like carbon fiber composites is many times higher than that of metals and alloys. "Creep" is the permanent deformation of a material under constant stress over a period of time. "Fatigue" is the brittle destruction of a material under repeated cyclic loading. Because of its semi-crystalline structure, PEEK has high creep and fatigue resistance and is more durable than many other polymers and metals over a long service life. - Does not ignite or burn easily PEEK has excellent flame resistance, with an ignition temperature of nearly 600°C. Even when ignited at very high temperatures, it does not burn continuously and emits little smoke. This is one of the reasons why PEEK is widely used in commercial aircraft. - Reprocessable and recyclable PEEK molecules are so stable that they can be melted and reprocessed time and time again with minimal impact on their properties. This helps to improve the environmental footprint and ensures more efficient reuse of waste materials generated during the manufacturing process. - And there's more! PEEK is also non-hygroscopic, so its properties are not altered in wet environments; it is resistant to gamma and electron beam radiation and is transparent under X-ray exposure, making it attractive for medical device applications.PEEK is also electrically stable and is typically used as an electrical insulator, but can be modified to become a conductor or static dissipative material. As a thermoplastic PEEK, it can be injection molded, compression molded and extruded using conventional thermoplastic processing equipment. It is very versatile and its use is becoming more and more common to improve component performance, durability, reduce weight and lower overall system costs over its lifetime. There is no doubt that it is replacing metals and alloys. In many industries and critical environments, material specialists, part designers and buyers must choose between PEEK and traditional metals a...

PPS-LCF In carbon fiber composites, carbon fiber reinforced PPS can be said to be a very promising new material, its mechanical properties, corrosion resistance, self-flame retardant and other aspects of the performance is good, so it is often used as a matrix material for various types of high-performance composite materials. The mechanical properties of carbon fiber reinforced polyphenylene sulfide are also affected by the carbon fiber content, under a certain threshold, the larger the carbon fiber content, the stronger the ability to bear external loads. Application Through the reinforcing intervention of carbon fibers, the toughness and strength of polyphenylene sulfide PPS can be substantially increased and improved, becoming one of the most commonly used composites in the aerospace field. Compared with metal, carbon fiber reinforced PPS has the advantages of low cost and easy processing, and the cost can be reduced by 20%-50%. Used in landing gear, wings, doors, fuel tank covers, J-type nose cones, cabin trim and other parts of the aircraft, it not only helps to increase the impact resistance, high temperature resistance and corrosion resistance of these parts, but also improves the load efficiency of the aircraft and reduces fuel consumption by reducing the quality. The most representative application example is the carbon fiber reinforced polyphenylene sulfide composite material for the leading edge of the wing of Airbus A340/A380 aircraft. Datasheet Carbon fiber reinforced PPS production products, with a fast molding, easier to mass production; carbon fiber reinforced PPS with environmental standards, but also able to be used twice, in the production of the entire product as well as the processing of solvents and additives do not need to be introduced, so it can reduce or even a certain degree of avoiding environmental pollution, but also thermoplastic products, unlike thermosetting composite materials can not be reused after the molding of the product, under certain temperature conditions, it has the possibility of recycling, regeneration and reuse. Moreover, unlike thermoset composite products that cannot be reused after molding, thermoplastic products have the possibility of recycling and reuse under certain temperature conditions. In addition, relative to thermoset products, thermoplastic composite products molding speed to be faster, shorter manufacturing cycle, which is conducive to reducing the cost of products.

Is there a unified reference data for carbon fiber product performance? The performance of specific carbon fiber filaments is fixed, such as Toray's carbon fiber filaments, T300, T300J, T400, T700 and so on, there are a series of parameters can be traced. However, there is no uniform standard to measure the carbon fiber composite products. Firstly, the different types of raw materials selected will lead to different performance of the products, and then due to the choice of matrix and the different design of the products, it will lead to different performance of the products. In addition to some common carbon fiber tubes, carbon fiber boards and other conventional parts, most of the carbon fiber products in the production of the sample before the test to determine whether the performance of the product is in line with the use of the expected standard, and as a base point, so as to carry out the production and use of large quantities. 2. Are carbon fiber composite products expensive? The price of carbon fiber composite products is closely related to the price of raw materials, the level of technology and the quantity of products. Some products of the industrial environment requirements are high, the performance of carbon fiber products and materials have special requirements, which requires the selection of specific raw materials, raw materials, the higher the performance of the natural price of the more expensive, such as the application of orthopedic carbon fiber PEEK thermoplastic materials. Of course, the more complex the production process, the greater t...

Car Tool Kit Automotive front-end components More application fields, please contact us for more technical advice. Frequently asked questions 1. What are the types of thermoplastic carbon fiber composites? Carbon fiber thermoplastic composites are composites with carbon fiber as reinforcing material and thermoplastic resin as matrix. From the reinforcement of carbon fiber, it can be divided into long-cut carbon fiber (LCF)-reinforced thermoplastic composites, short-cut carbon fiber (SCF)-reinforced thermoplastic composites and continuous carbon fiber (CCF)-reinforced thermoplastic composites. Long-cut carbon fiber and short-cut carbon fiber mainly refers to the application length of carbon fiber materials, there is no strict fixed distinction between the two, generally between a few millimeters to a few centimeters, the more common specifications are 6mm, 12mm, 20mm, 30mm, 50mm. Carbon fiber thermoplastic composites can also be classified according to the thermoplastic resin, there are many common thermoplastic resins, such as PE, PP, PVC, etc., but the thermoplastic resin composites reinforced with carbon fibers are mostly used in aerospace, precision equipment, and other demanding working environments, so the carbon fiber thermoplastic composites are more commonly used in the form of polyetheretherketone (PEEK), PPS, polyimide ( Therefore, carbon fiber thermoplastic composites more often use polyether ether ketone (PEEK), PPS, polyimide (PI), polyetherimide (PAI) and other high-end thermoplastic resins as the matrix, to achieve the optimization of the material performance through the way of "strong alliance". 2. How do thermoplastic carbon fiber composites achieve low cost and environmental protection? Thermoplastic carbon fiber composites are used to make parts for high-end machinery, and they have excellent machinability, vacuum forming, stamping mold plasticity and bending processability, etc. Moreover, as long as the material reaches a certain temperature again, it can be remolded, which is recyclable and environmentally friendly in terms of the characteristics of the material itself. For example, Teijin Japan has been able to design a recycling process in the process according to the special needs, and the punched thermoplastic carbon fiber composite material trimmings are shredded, injection molded, and made into recycled materials, which can be used to make small products or injection molded nuts and studs on the carbon fiber prototype parts. This method can reduce the loss of raw materials to a greater extent, improve the use of thermoplastic carbon fiber composite materials, reduce the overall cost, so as to achieve the purpose of environmental protection. Production process of thermoplastic carbon fiber products In addition, thermoplastic carbon fiber composites, compared with thermoset carbon fiber composites, can shorten the molding cycle time due to its special process characteristics, which can further cut down the production cost in terms of production efficiency. 3. Are thermoplastic carbon fiber composites only suitable for injection molding? From the process point of view, injection molding and compression molding compared to a higher degree of automation, the raw material does not contact with the outside world, so the product appearance quality is guaranteed, there will be no black spots, impurities, uneven color and other issues, the mechanical properties of the product, dimensional stability and precision is relatively higher. At present, Toray, Japan, these carbon fiber giants in the application of carbon fiber reinforced thermoplastic composite materials, the main use of injection molding method, and this method is suitable for the production of complex shaped parts and mass production.

Polyamide 12 PA12, nylon 12, also known as polydodecalactam and polylactam, is a long carbon chain nylon. There are non-polar methylene groups in nylon 12, and the number is large, which makes the flexibility of nylon 12 molecular chain larger; the amide group in nylon 12 is polar, and the cohesion energy is large, and it can form hydrogen bonds between molecules, which makes the arrangement of molecules more regular. Therefore, the crystallinity of nylon 12 is high, and the strength is also higher. Nylon 12 (PA12) has low water absorption, good low temperature resistance, good air tightness, excellent alkali resistance, grease performance, medium resistance to alcohols and inorganic dilute acids and aromatics, good mechanical properties and electrical properties, and is a self-extinguishing material. 1) Density The relative density of nylon 12 is only 1.01-1.03, which is the smallest among all engineering plastics, which has a certain effect on reducing the mass of the car and lowering the fuel consumption. If compared by unit volume, nylon 12 has advantages in price and performance. 2) Melting point The melting point of nylon 12 is 172-178℃, which is slightly lower than that of nylon 11, and it can fully meet the working temperature requirement of automobile fuel and air brake pipes. 3）Water absorption As we all know, the biggest drawback of nylon products is the large water absorption, and it is difficult to ensure the dimensional stability. However, due to the increase of methylene molecules in nylon 12, the influence of hydrophilic groups is greatly reduced, therefore, nylon 12 has the lowest water absorption rate among nylon products, which reduces the change of performance and size of products caused by water absorption, which makes nylon 12 have great advantages. After water absorption, the tensile strength of nylon 12 decreases very little, while nylon 66 and nylon 6 have great changes. 4) Impact strength Impact strength is an important technical index, and it is especially important for nylon 12 tubes that are often exposed to air. Nylon 12 at -20 ℃ and -40 ℃ according to the standard test, no fracture phenomenon, fully meet the requirements of use. Nylon 12 impact resistance is very good. 5）Low temperature performance Nylon 12 has the lowest brittleness temperature of -70 degrees Celsius, so it can be widely used for parts with low temperature resistance. 6) Flexibility The effect of plasticizers on the physical properties of nylon 12 is concentrated on the elastic modulus of the resin. There are three basic types of nylon 12 resins, the main difference between them is the different plasticizer content and the formation of different flexibility. As the content of plasticizer extractable components increases, the elastic modulus of the resin decreases. 7）Low abrasion and low friction properties Nylon 12 has excellent low-wear and low-friction properties and self-lubricating properties, so the frictional noise of Nylon 12 products is very low. 8）Fuel resistance In the automobile, the current use of oxygenated fuel, high aromatic fuel and alcohol mixed fuel will lead to the decomposition of many hose materials. Only nylon 11, nylon 12 and fluorocarbon elastomers have been tested for use in this environment. Under the action of motor fuels, all nylons dissolve, resulting in dimensional changes, especially in methanol-containing gasoline, where nylons containing large amounts of amide groups such as nylon 6 dissolve much more than nylons containing small amounts of amide groups such as nylon 12 %. It is found that the fuel containing 15% methanol has a great effect on nylon. 9) Resistant to zinc chloride solution Zinc chloride will appear in the environment under the car. Under certain temperature and humidity, the salt on the road reacts with galvanized steel or zinc-containing primer to form a small amount of zinc chloride. Zinc chloride is highly corrosive, but Nylon 12 is highly resistant to zinc chloride solutions. Ozone aging, UV exposure, temperature conditions, etc., can bring varying degrees of damage to parts and reduce service life. Since nylon 12 does not contain the + 2 3 2 + unsaturated double bond, which is susceptible to ozone attack, it does not suffer from ozone aging. In addition, the high crystallinity of nylon 12 and its high melting temperature make it more stable in terms of heat resistance, and the addition of heat stabilizers increases its heat resistance exponentially. When exposed to sunlight, its energy can cause the chemical bonds of organic materials to break. The bonding energy of C-H, C-O and C-N bonds in nylon 12 is so large that UV light is not enough to break them, but only the C-C bonds with smaller bonding energy; therefore, after adding appropriate anti-aging agents to the raw materials, the UV resistance of nylon 12 is excellent.

Polyamide 6 plastic Nylon 6 (PA6), also known as polyamide 6, nylon 6, its mechanical strength and crystallinity is good, and has corrosion resistance, wear resistance and other characteristics, in the automotive industry, rail transportation, film packaging, electronic appliances and textiles and other major fields to achieve a wide range of applications. Although its comprehensive performance, but also has a series of shortcomings, such as PA6 does not have too strong resistance to strong acid and alkali, low temperature, dry state impact strength is not high, the presence of hydrophilic groups will cause high water absorption, modulus of elasticity, creep resistance, impact strength and other water absorption will be significantly reduced, thus affecting the dimensional stability of the product, but also affect the electrical properties of the product. Therefore, it is necessary to do a good research on the modification of PA6. Polyamide 6 filling long carbon fiber Carbon fiber reinforced composites are composite materials composed of high strength fibers and elastic plastics, which have high stiffness and strength, making the products superior heat resistance, excellent impact resistance, and good dimensional stability, meeting their requirements for use in industrial and everyday aspects. PA6-LCF has higher stiffness and strength than traditional polyamide, and the addition of carbon fiber increases the thermal stability of the material and improves its wear resistance, making it a composite material with high strength, high impact resistance and resistance to thermal deformation.

Long carbon fiber (LCF) Carbon fiber was first used in aviation, military and other fields, and later was cited in the production of racing car parts. In recent years, it began to come into the consumer market, and is also one of the materials that international manufacturers are keen on. Carbon fiber composite materials are characterized by very light, rigid, and can withstand the same pressure as steel, the cost is higher. However, the material is more durable and has a high recycling value, so it can save costs to a certain extent. Carbon fiber composites include carbon fiber powders, short fibers, long fibers, and long fiber reinforced composites. Long carbon fiber composites have better mechanical properties than short carbon fiber composites, but there are certain requirements for the injection molding machine and mold of the product. Carbon fiber has excellent mechanical properties and chemical stability, lower density than aluminum, higher strength than steel, is the highest specific strength and highest specific modulus among the high-performance fibers that have been produced in large quantities, and has the characteristics of low density, corrosion resistance, high temperature resistance, friction resistance, fatigue resistance, high electrical and thermal conductivity, low coefficient of thermal and wet expansion, etc. It is an important strategic material for the development of national defense and national economy. The characteristics of corrosion resistance, high temperature resistance and low coefficient of expansion make it an alternative material to metal materials in harsh environments; the electrical and thermal conductivity properties expand its application in the field of communications and electronics; as the highest specific strength (strength to density) and highest specific stiffness (modulus to density) among the high-performance fibers currently in mass production, carbon fiber is an important material for aerospace, wind power blades, new energy vehicles, transportation, sports and leisure, etc, Carbon fiber is an ideal material for aerospace, wind power blades, new energy vehicles, transportation, sports and leisure, and other fields with light weight needs. Xiamen LGT-G LCF compounds have the following appearance: Flat grain, very light weight, shows flawless finish, no floating fibers, bubbles, etc. The color is natural black and the length is around 6 to 25 mm. Application Datasheet for reference Homo-PP & Copo-PP PP is divided into homopolymer PP and copolymer PP according to the different types of monomers involved in polymerization. Homopolymer PP is made by polymerization of propylene monomer only, and there is only one kind of link in the polymer molecular chain, with high crystallinity and good mechanical properties and heat resistance. Copolymerized PP is mainly made of propylene monomer and ethylene monomer, and there are ethylene links in addition to propylene links in the polymer molecular chain, which has high impact resistance. HPP composites and CPP composites, both of them are available for us.
