  • Jewelers experiment with 3D-printed bracelets made of fiberglass composites
    In jewelry, 3D-printed metal jewelry has been popular, while other materials have not. Perhaps not afraid of the tiger, jewelry brand Eternha, founded in 2020, has been experimenting with making men's bracelets out of composite materials. They chose nylon and glass fiber composite material, an industrial material commonly used in automotive and aerospace fields, as well as a material commonly used in the field of 3D printing at present. It has good impact resistance and toughness, presents a deep luster after hand polishing, and is approved for skin contact. Instead of 3D-printing the entire string of bracelets, Eternha 3D-printed the beads of the bracelet and combined them with obsidian, 925 silver, and stainless steel beads to create a multi-material mix of bracelets. Eternha says they want to incorporate a variety of elements into their bracelets, with 3D-printed nylon glass fiber beads that can be designed in a variety of shapes (cylinders, hexahedrons, irregular shapes, etc.) and the ability to incorporate logos such as logos to create unusual fashion pieces. LFT-G PA6-NA-LGF LFT & LFRT, Long fiber reinforced thermoplastic engineering plastics, compared to conventional short fiber reinforced thermoplastics, typically have a fiber length of less than 1 to 2 mm in conventional short fiber reinforced thermoplastics, while the LFT process The thermoplastic engineering plastics produced have been able to maintain fiber lengths above 5 to 25 mm. The long fiber is impregnated with a special resin system to obtain a long strip which is sufficiently wetted by the resin, and then cut into a desired length as required. The most used matrix resin is PP, followed by PA6, PA66, PPA, PA12, MXD6, PBT, PET, TPU, PPS, LCP, PEEK and the like. Conventional fibers include glass fiber and carbon fiber. Special fibers include basalt fiber and quartz fiber. The LFT of the long fiber material can achieve better mechanical properties. According to the final different applications, the finished product can be used for injection molding, extrusion and molding, etc., directly used to replace steel and thermoset products.
  • The construction field has become one of the most promising application markets for fiber reinforced composites
    Fiber reinforced composite materials such as glass fiber, carbon fiber and glass fiber reinforced plastic have been widely used as building materials, mainly in structural reinforcement, glass fiber reinforced plastic tile and glass fiber reinforced pultrusion profiles. According to a report released by research firm MarketsandMarkets, the global construction composites market is expected to reach $8.98 billion by 2026, with a CAGR of 6.00% over the forecast period. The construction field has become the most potential fiber composite application market after the automobile, aerospace. Now, let's take a look at some of the world's most famous buildings using fiber-reinforced composites. 1. Eu Prosecutor's Office building The Dutch TGM construction company, Indupol, Linkvision, BuFA and Solico, through close and successful cooperation, successfully realized the unique design and shape of the facade of the EU Prosecutor's Office building, infusing innovative composite material application technology into the construction industry. The composite parts were manufactured by Indupol and moulded with a hand paste process to obtain specific shapes and sizes using resin from Liansi and Bufa (delivered by distributor Euroresins). After the molding, the finished product is treated and coated with white topcoat before being transported to the installation site. The installation of the product requires only a small amount of scaffolding, which is lifted by a crane and mounted onto the building. 2. The Building of Newtown Primary School, Calcutta, India Designer Abin Chaudhuri of Abin Design Studio has created a unique landmark for Newtown Primary School in Kolkata, India. From a distance, each facade looks like an intricate Rubik's Cube® with letters and mathematical symbols. The letters and symbols create a kind of custom template for the facade. These structures provide children with a graphical but interesting aesthetic experience. Due to the need for a wide variety of complex shapes that are durable and lightweight, the team created 488 panels measuring 3.2 x 3.2 meters from glass fiber-reinforced composites, each consisting of 13 different combinations of symbols. After experimenting with several different composites and non-composites, the team determined that a fiberglass felt-reinforced polypropylene system best met its needs. Each plate weighs only 154 pounds. A grid-like frame made of steel is matched with FRP plates, and Z-shaped steel is embedded in the plates and fastened to the building. Structural concrete slabs protrude from the surface of the building to ensure that a precise number of slabs can be installed on all surfaces of the facade. This makes the panels easier to install from behind and ensures better lighting. The panels are mounted in different directions, giving the facade a random effect. When completed, this facade wraps around a 27,000 square foot building. 3. San Francisco Museum of Modern Art (SFMOMA) Kreysler & Associat...
  • Design and application of comtailgateposite
    Energy saving and environmental protection have become an inevitable trend in the development of the automobile industry in the 21st century. Automobile lightweight is an effective way to realize energy saving and environmental protection. Composite materials have played an important role in the process of automobile lightweight. The report of the World Aluminum Association pointed out that for every 10% reduction in the quality of the car itself, the fuel consumption can be reduced by 8%. The traditional ordinary steel body structure can reduce weight by more than 10% through structural optimization design and the use of high-strength steel plates. The use of all-aluminum body can achieve a weight reduction effect of more than 25%, and the use of fiber-reinforced plastic composite materials can achieve a weight reduction of more than 50%. Heavy effect. Most of the existing car tailgates are formed by sheet metal stamping and welding, with a large number of parts, high quality, and low degree of freedom in modeling. Plastic composite materials are widely used in automobile lightweight due to their low density, specific rigidity and high specific strength. In recent years, many lightweight plastic tailgates have appeared. Compared with traditional automobile sheet metal tailgates, they have the following advantages: (1) Lightweight: By using fiber-reinforced materials to replace traditional steel materials, while considering the overall integration and optimization of plastic tailgate parts, the mass can be reduced by 30%-50% (5-8 kg). In addition, the reduced quality of the car can bring a good user experience: reduced fuel consumption/ increased cruising range, improved acceleration performance, reduced operating force for opening and closing the tailgate, etc. (2) Novel shape: Due to the variable thickness of the fiber reinforced material and the high degree of freedom of shape, the appearance shape that may not be able to be manufactured by using traditional materials can be realized. The complex modeling curve and stylish and beautiful appearance of the plastic tailgate can meet the increasing requirements of users for car styling (3) Integration: The use of plastic tailgates reduces the number of parts of the tailgate, and the interface and gaps of the tailgate are removed to enhance the sense of integration of the tailgate components; in addition, the use of plastic tailgates can improve manufacturing efficiency: no more stamping workshops Stamping is required; the painting workshop does not need tailgate painting, which reduces the coating process beat; at the same time, after using plastics, the overall injection molding can be achieved with high strength and light weight, which greatly reduces the number of parts and reduces the assembly pressure of the assembly workshop, as listed in Table 1. The composite material tailgate has the advantage of manufacturing process compared with the traditional automobile tailgate integration. The plas...
  • What are the causes of cracks, cracks, microcracks, and whitening in injection mold molding?
    Whether it is the production of long-fiber modified injection molded products or ordinary modified material injection molded parts, there may be cracks and cracks in the finished product in the injection molding process. So what is the reason for the above situation? Cracking includes filamentous cracks, microcracks, whitening, cracking, and trauma crisis caused by the sticking of parts and runners. According to the cracking time, it is divided into demoulding cracking and application cracking. Two of the cases are analyzed as follows: 1. The plasticizing capacity of the injection molding machine of the injection molding machine should be appropriate. If it is too small, the plasticization will not be fully mixed and it will become brittle. If it is too large, it will degrade. 2. In terms of molds: (1) The ejection should be balanced, such as the number of ejector pins, the cross-sectional area should be sufficient, the demolding slope should be sufficient, and the cavity surface should be smooth enough, so as to prevent the ejection residual stress from being concentrated and cracking due to external force. (2) The structure of the part should not be too thin, and the transition part should use arc transition as much as possible to avoid stress concentration caused by sharp corners and chamfers. (3) Appropriate demoulding air inlets should be provided for deep-bottomed parts to prevent the formation of vacuum negative pressure. (4) The main runner is sufficient to allow the gate material to be demolded when it is solidified in the future, so that it is easy to demold. (5) The sprue bushing and the nozzle joint should prevent the dragging of the chilled material to make the parts stick to the fixed mold. (6) Runners and gates are too small, resulting in excessive shear rate during mold filling. Use full-circle runners and increase the size of runners and gates to provide acceptable shear rates during mold filling. If you have any question,pls contact us.

  • What is modified plastic and long fiber modified plastic
    The so-called "plastic modification" means that by adding one or more other substances in plastic resin, to achieve the purpose of changing its original properties, improve one or many properties, so as to achieve the purpose of expanding its scope of application.The modified plastic materials are referred to as "modified plastics". Plastic chemical research and development up to now, thousands of polymer materials have been made, of which only hundreds kinds of industrial value, commonly used plastic resin raw materials more than 90% on the five general resin (PE, PP, PVC, PS, ABS), now continue to synthesis of new polymer materials is very difficult, neither economic nor practical. Therefore, it has become one of the effective ways to develop the plastic industry to study the relationship between the composition, structure and properties of polymers, and on this basis to modify the existing plastics to manufacture suitable new plastic materials. Therefore, the global modified plastics industry has achieved considerable development in recent years. Plastic modification refers to the physical, chemical or both methods to make the properties of plastic materials to people's expected direction change, or to significantly reduce the cost, or to improve some properties, or to give plastic materials a new function.The modification process can occur in the process of polymerization of synthetic resin, that is, chemical modification, such as copolymerization, grafting, crosslinking, etc., or in the process of processing of synthetic resin, that is, physical modification, such as filling, blending, strengthening, etc. Through glass fiber and carbon fiber modified materials, can significantly improve the rigidity, strength, hardness, heat resistance of materials, improve the mechanical or other properties of resin, and resin can play a role in adhesion and load transfer of reinforced materials, so that reinforced plastic has excellent performance.
