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.

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. Are there any special process requirements of long carbon fiber for the injection molding products? A. We must consider the requirements of long carbon fiber for the injection molding machine screw nozzle, mold structure and injection molding process. Long carbon fiber is a relatively high cost material, and need to evaluate the cost performance problem in the selection process. Q. What are the advantages of long carbon fiber materials? A.  The thermoplastic LFT long carbon fiber material has high rigidity, good impact strength, low warpage, low shrinkage, electrical conductively and electrostatic properties, and its mechanical properties are better than glass fiber series. Long carbon fiber has the characteristics of lighter and more convenient processing to replace metal products. Q. The cost of long fiber products is higher. Does it has a high recycling value? A. The thermoplastic LFT long fiber material can be recycled and reused very well.
