    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.

    Material Introduction In 1935, Wallace Carothers, a scientific researcher at DuPont, and his team successfully synthesized PA66 by condensation of adipic acid and adipic diamine for the first time, and DuPont completed the commercial production of PA66 fiber in 1939. Starting in the 1950s, PA, including PA6 and PA66, was developed for the production of injection molded products to replace metal to meet the requirements of light weight and cost reduction of industrial products. At present, PA66 is the most used PA species other than PA6. PA66 Scientific name: Polyhexanediamide Abbreviation: PA66 Common name: Nylon 66  PA66 has many similarities with PA6. PA66 is also a transparent to milky white granule that can take on almost any color with the addition of a colorant (masterbatch) specific for polymers. Material properties Similar to the basic properties of PA6, PA66 also has low specific gravity, high tensile strength, wear resistance, good self-lubrication, and excellent impact toughness. In addition, because the number of hydrogen bonds in PA66 is more than in PA6, the intermolecular force of PA66 is stronger than the intermolecular force of PA6, which makes the internal structure of PA66 more compact than PA6, with better thermal properties, higher rigidity and toughness, better dimensional stability, lower water absorption, and more wear resistance. However, PA66 has a higher market price than PA6 and is not as easy to process and mold as PA6. Like PA6, PA66 can also add a certain percentage of glass fiber, carbon fiber, etc. to improve the performance and meet the application needs of different products. The following table is a PA66-LCF30 performance table produced by Xiamen LFT composite plastic company. Materials Application PA66 has higher hardness, mechanical strength, toughness, self-lubrication, friction resistance, heat resistance after the addition of carbon fiber, and is widely used in automotive parts, electrical and electronic, as well as mechanical and engineering parts and other fields.
