Long Carbon Fiber Reinforced Polymer (LCFRP) is composed of carbon fiber as the reinforcement material and resin as the matrix material

PA6 material PA6 is one of the most widely used materials in the current field, and PA6 is a very good engineering plastic with balanced and good performance. The raw materials for the manufacture of nylon 6 engineering plastic are extensive and inexpensive, and it is not restricted by the technological monopoly of foreign companies. However, in order to make good use of this inexpensive and excellent material, we must first understand it. Today, we will start with glass fiber reinforced PA6 engineering plastics, because it is the most important category of PA6 engineering plastics. Just like any other engineering plastics, PA6 has advantages and disadvantages, such as high water absorption, low temperature impact toughness and dimensional stability is relatively poor. So engineers will use different methods to make PA6 better, which we call modification. At present, the most common method is to blend and modify PA6 with glass fiber (GF). Today, we will take a look at the mechanical properties of PA6 engineering plastics under the glass fiber GF system for reference and help us select materials. PA6-LGF 1. Influence of glass fiber content on PA6 engineering plastics We can find from the application and experiment that the content index is often one of the biggest influencing factors in fiber reinforced composites. As the glass fiber content increases, the number of glass fibers per unit area of the material will increase, which means that the PA6 matrix between the glass fibers will become thinner. This change determines the impact toughness, tensile strength, bending strength and other mechanical properties of glass fiber reinforced PA6 composites. In terms of impact performance, the increase of glass fiber content will greatly increase the notch impact strength of PA6. Taking long glass fiber (LGF) filling PA6 as an example, when the filling volume increases to 35%, the notch impact strength will increase from 24.8J/m to 128.5J/m. But the glass fiber content is not more is better, short glass fiber (SGF) filling volume reached 42%, the impact strength of the material reached the highest 17.4kJ/㎡, but continue to add will let the gap impact strength showed a downward trend. In terms of bending strength, the increase of the amount of glass fiber will make the bending stress can be transferred between the glass fiber through the resin layer; At the same time, when the glass fiber is extracted from the resin or broken, it will absorb a lot of energy, thus improving the bending strength of the material. The above theory is verified by experiments. The data show that the bending elastic modulus increases to 4.99GPa when the LGF (long glass fiber) is filled to 35%. When the content of SGF (short glass fiber) is 42%, the bending elastic modulus reaches 10410MPa, which is about 5 times that of pure PA6. 2. Influence of glass fiber retention length on PA6 composites The fiber length of the glass fiber also has an obvious effect on the mechanical properties of the material. When the length of the glass fiber is less than the critical length (the length of the fiber when the material has the tensile strength of the fiber), the interface binding area of the glass fiber and the resin increases with the increase of the length of the glass fiber. When the composite material is broken, the resistance of the glass fiber from the resin is also greater, so as to improve the ability to withstand the tensile load. When the length of glass fiber exceeds the critical, the longer glass fiber can absorb more impact energy under impact load. In addition, the end of the glass fiber is the initiation point of crack growth, and the number of long glass fiber ends is relatively less, and the impact strength can be significantly improved. The experimental results show that the tensile strength of the material increases from 154.8MPa to 164.4MPa when the glass fiber content is kept at 40% and the length of the glass fiber increases from 4mm to 13mm. The bending strength and notched impact strength increased by 24% and 28%, respectively. Moreover, the research shows that when the original length of the glass fiber is less than 7mm, the material performance increases more obviously. Compared with short glass fiber, long glass fiber reinforced PA6 material has better appearance warping resistance, and can better maintain mechanical properties under high temperature and humidity conditions. TDS for your reference PA6 can be made into long glass fiber reinforced material by adding 20%-60% long glass fiber according to the characteristics of the product. PA6 with long glass fiber added has better strength, heat resistance, impact resistance, dimensional stability and warping resistance than without glass fiber added. Following TDS show the data of PA6-LGF30. Application PA6-LGF has the largest proportion of applications in the automotive industry, by electronic and electrical applications, and also involving machinery and engineering ...

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.

PEEK-LCF Polyether ether ketone (abbreviated PEEK) not only has excellent mechanical, heat and chemical resistance properties, and low friction coefficient, good bearing meshing, is another kind of good self-lubricating material after polytetrafluoroethylene (PTFE), in the bearing capacity and wear resistance than PTFE performance is better, In no lubrication, low speed and high load, high temperature, humidity, pollution, corrosion and other harsh environment is especially suitable. On this basis, the addition of carbon fiber not only enhances its mechanical properties, its friction performance has important ‌ influence. At room temperature, the tensile strength of 30% carbon fiber reinforced PEEK composite doubled, and reached three times at 150℃. At the same time, the impact strength, bending strength and modulus of the reinforced composite were also greatly improved, the elongation was sharply reduced, and the thermal deformation temperature could exceed 300℃. The impact energy absorption rate of the composite directly affects the impact performance of the composite. The carbon fiber reinforced PEEK composite shows a specific energy absorption capacity of up to 180kJ/kg. The reinforced effect of carbon fiber can also resist the thermal softening of PEEK and form a transfer film with very high strength to a certain extent, which can effectively protect the contact area. Therefore, the friction coefficient and specific wear rate of carbon fiber reinforced PEEK composite are significantly lower than that of pure PEEK. Under the same experimental conditions, the friction and wear resistance of carbon fiber reinforced PEEK composites is obviously better than that of glass fiber PEEK composites, and the improvement effect of carbon fiber on the wear resistance of materials is more than 5 times that of glass fiber with the same dosage. Carbon fiber reinforced PEEK composite material is used in parts manufacturing, which can effectively avoid the surface cracks of metal or ceramic materials, and its excellent tribological properties even exceed that of ultra-high molar mass polyethylene. TDS Application Long carbon fiber reinforced PEEK is mainly applied in the following four areas: 1. Electronic and electrical appliances PEEK can maintain good electrical insulation in the harsh environment such as high temperature, high pressure and high humidity, and has the characteristics of non-deformation in a wide temperature range, so it is used as an ideal electrical insulation material in the field of electronic and electrical appliances. The mechanical properties, chemical corrosion resistance, radiation resistance and high temperature resistance of polyether ether ketone reinforced by carbon fiber have been further improved, and its application fields have been further expanded. 2. Aerospace Polyether ether ketone PEEK has the advantages of low density and good workability, so it is easy to be directly processed into high-demand parts, and carbon fiber reinforced polyether ether ketone composite material further enhances the overall performance of polyether ether ketone, so it is increasingly used in aircraft manufacturing. The fairing on Boeing's 757-200 series aircraft, for example, is made from carbon-fiber reinforced PEEK. In addition, Gereedschappen Fabrick of Amsterdam, the Netherlands, used a 30% carbon fiber reinforced PEEK composite to build a larger component and demonstrated that its mechanical properties could be used in aircraft balancing devices. 3. Automotive Automobile energy consumption is closely related to vehicle weight. Automobile lightweight can not only reduce fuel consumption and exhaust emissions, but also improve power performance and safety, which is an effective way to save energy. In addition to the lightweight design of the structure, the use of lightweight materials is a more direct method. With its advantages of low density, good performance and convenient technology, carbon fiber reinforced polyether ether ketone composites are more and more frequently used in the automobile industry, and show great potential of replacing steel with plastic. For example, Robert Bosch GmbH uses carbon fiber reinforced PEEK instead of metal as a feature of ABS. The lighter composite part reduces moment of inertia, which minimizes reaction times, greatly enhances the overall system's reactivity, and reduces costs compared to previously used metal parts. 4. Healthcare Currently available medical polymer materials are polytetrafluoroethylene, polylactic acid, silicone rubber and dozens of kinds, but from the point of view of biomedicine, these materials are not ideal, in the use of some side effects, and PEEK resin because of its non-toxic, light weight, abrasion resistance and other advantages, is the material closest to the human skeleton, can be organically combined with the body, Therefore, polyether ether ketone resin and its composite materials have been deeply studied and applied in spine and joint...

PPS Information Polyphenylene sulfide (PPS) is not enhanced before modification, its disadvantages are brittle, poor toughness, low impact strength, after filling glass fiber, carbon fiber and other enhancements modified to overcome the above shortcomings, to obtain very good overall performance. PPS filling Long carbon fiber In the modified engineering plastics industry, long fiber reinforced composites are composites made from long carbon fibers, long glass fibers and polymer matrix through a series of special modification methods. The most important feature of long fiber composites is that they have superior performance that the original materials do not have. If we classify them according to the length of the reinforcing materials added, they can be divided into: long fiber, short fiber and continuous fiber composites. Long carbon fiber composites are one kind of long fiber reinforced composites, which are a new fiber material with high strength and high modulus. It is a new material with excellent mechanical properties and many special functions. Corrosion resistance: LCF carbon fiber composite materials have good corrosion resistance and can adapt to the harsh working environment. UV resistance: the ability to resist UV is strong, and the products are less damaged by UV. Abrasion and impact resistance: the advantage of comparing with general materials is more obvious. Low density: lower density than many metal materials, can achieve the purpose of light weight. Other properties: such as reducing warpage, improving rigidity, impact modification, increasing toughness, electrical conductivity, etc. LCF carbon fiber composites have higher strength, higher rigidity, lower weight, and excellent electrical conductivity compared with glass fiber. PPS TDS for reference PPS Application Other products you can also contact us for more technical advice. Q&A 1. Are carbon fiber composite products very expensive? The price of carbon fiber composite products is closely related to the price of raw materials, the level of technology and the number of products. The higher the performance of the raw material, the more expensive it is, such as the carbon fiber PEEK thermoplastic material used in orthopedics. Of course, the more complex the manufacturing process, the greater the working time and workload, and the increased production costs. However, the larger the order quantity, the lower the cost per product. In the long run, the superior performance of carbon fiber will extend the life of the product, reduce the number of maintenance, and is also very beneficial to reduce the cost of use. 2. Are carbon fiber composite products toxic? Carbon fiber composites are made of carbon fiber filaments mixed with ceramics, resins, metals and other substrates, and are generally not toxic. For example, the above-mentioned PEEK material is made of food-grade resin, which is very compatible with the human body and is not only harmless to humans, but also becomes a more ideal material for orthopedic surgery because of its high strength and elastic modulus close to the bone cortex. Carbon fiber medical bed plate, will be in daily contact with many patients body, will not have adverse effects on the human body, on the contrary, for the accuracy of medical diagnosis and a great help. 3. What is the difference between thermosetting carbon fiber composites and thermoplastic carbon fiber composites? Thermoset carbon fiber composites favor the role of curing agent in curing and molding. While thermoplastic carbon fiber composite products mainly rely on cooling down to achieve the shaping. Thermoplastic carbon fiber composites are not as popular as thermoset carbon fiber composites, mainly because they are expensive and are generally used in high-end industries. Thermoset carbon fiber composites are difficult to recycle due to the limitation of the resin matrix itself, and are generally not considered; thermoplastic carbon fiber composites can be recycled, and can be made twice as long as they are heated to a certain temperature.
