Polyamide 66 Nylon is the common name for polyamide (PA), a generic term for thermoplastic resins containing repeating amide groups on the main chain of the molecule, including aliphatic polyamides, aliphatic-aromatic polyamides and aromatic polyamides. As one of the top five engineering plastics, nylon has an extremely wide range of industrial applications, mainly in automotive parts, mechanical parts, electronics and appliances, cosmetics, adhesives and packaging materials. Among them, the largest production and most widely used are aliphatic polyamides, mainly nylon 66 and nylon 6. Nylon 66 (PA66) is made by condensation of adipic acid and hexanediamine, which is a class of polyamide. Advantages: high strength, corrosion resistance, good wear resistance characteristics, and has self-lubricating, flame retardant, non-toxic environmental protection and other excellent performance. Disadvantages: poor heat resistance and acid resistance, low impact strength in dry state and low temperature, high water absorption affects the dimensional stability and electrical properties of products. Polyamide 66 filling long carbon fiber High-performance fibers are chemical fibers with high load-bearing capacity and high durability because they have a special physical or chemical structure embodied with some excellent characteristics that traditional fibers do not have, such as high temperature resistance, corrosion resistance, flame retardancy and other properties. Carbon fiber is an inorganic polymer material with carbon content higher than 90% obtained from organic fibers through carbonization and graphitization. Advantages: light weight, high strength, high modulus, high temperature resistance, wear resistance, corrosion resistance, fatigue resistance, electrical conductivity, thermal conductivity, etc. Disadvantages: high cost, relatively difficult to infiltrate, poor transparency, etc. Carbon fiber composite materials are very useful structural materials, which are not only light, high temperature resistant, but also have high tensile strength and elastic modulus, and are indispensable materials for the manufacture of spacecraft, rockets, missiles, high-speed aircraft and large passenger aircraft. In transportation, chemical industry, metallurgy, construction and other industrial sectors, as well as sports equipment and other aspects have a wide range of applications. The density of PA66/CF composites tends to increase slightly as the content of CF increases. This is due to the fact that the density of CF is larger compared to that of PA66. The fracture surface of PA66 is smoother, while the fracture surface of PA66/CF sample is extremely rough and CF is pulled out, which indicates that the CF in the system plays a good role in bearing the load when the composite sample is subjected to external force, and this fracture is a ductile fracture, therefore, PA66/CF composite is a ductile material. With the increase of CF content, the tensile strength of PA66/CF composites increased significantly. The flexural strength and flexural modulus of PA66/CF composites are increased substantially with the increase of CF content.
