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. Automotive parts PA66's low specific gravity, high rigidity, strong toughness, heat resistance and gasoline resistance make it widely used in automotive modules, automotive structural parts, automotive interior and exterior parts, automotive transmission system and chassis shield, automotive fuel system, automotive ignition system, etc. The products involve automotive cable channel modules, structural parts of front-end components of automotive sunroof system, automotive rearview mirror bracket, automotive radiator, headlight support frame, door module, seat structural parts, seat shell and backrest, dashboard skeleton, air cooler fan, etc. Electrical and electronics PA66's good insulation, flame retardancy and corrosion resistance make it suitable for making various connectors, switches, sockets, terminal blocks, wire coverings, wire ties, insulating spacers, circuit breaker housings, transformer bobbins, retaining clips and motor parts after glass fiber reinforcement. Mechanical and engineering parts PA66's good rigidity, toughness, self-lubricating properties, heat and abrasion resistance make it suitable for manufacturing various nuts, screws, cable ties, worm gears, rotating wheels, gears, pump impellers, pulley sleeves, bushings, solenoid distribution valve seats, power tool housings, pipes, luggage racks, fan housings, appliance housings, door and window frames, cable drag chains and large machine tool baffles.

Polyamide series Nylon is the common name of polyamide (PA), is the general term for thermoplastic resins containing repeated amide groups on the main chain of the molecule, including aliphatic polyamide, aliphatic aromatic polyamide and aromatic polyamide. As the first of the five engineering plastics, nylon has an extremely wide range of industrial applications, mainly used in automotive parts, mechanical parts, electronic and electrical appliances, cosmetics, adhesives and packaging materials and other fields. Among them, aliphatic polyamide, mainly nylon 66, is the most productive and widely used. Polyamide66 Nylon 66 (PA66) is a kind of polyamide formed by the condensation of adipic acid and adipdiamine. The molecular formula is shown in the figure Advantages: high strength, corrosion resistance, good wear resistance, and has self-lubrication, flame retardant, non-toxic environmental protection and other excellent performance. Disadvantages: poor heat and acid resistance, low impact strength in dry state and low temperature, water absorption greatly affects the dimensional stability and electrical properties of products. Long carbon fiber filling PA6 Long carbon fiber is an inorganic polymer material with more than 90% carbon content, which is obtained by carbonization and graphitization of organic fibers. The microstructure of long carbon fiber is similar to that of artificial graphite (C atoms arranged in layers). Advantages: light weight, high strength, high modulus, high temperature resistance, wear resistance, corrosion resistance, fatigue resistance, electrical and thermal conductivity, etc. Disadvantages: high cost, relatively difficult to infiltrate, poor transparency, defects difficult to check, etc. According to the source of carbon fiber, long carbon fiber can be divided into: Polyacrylonitrile-based long carbon fiber Asphaltic long carbon fiber Viscosified long carbon fiber Long carbon fiber composite material is a very useful structural material, it is not only light, high temperature resistance, but also has a high tensile strength and elastic modulus, is the manufacturing of spacecraft, rockets, missiles, high-speed aircraft and large passenger aircraft indispensable components of the material. It is also widely used in transportation, chemical industry, metallurgy, construction and other industrial sectors as well as sports equipment. Datasheet for reference The density of A66/CF composite material is less than 1.3, which is less than one sixth of the density of steel (7.85), achieving the purpose of lightweight, which is conducive to energy saving and consumption reduction. In the PA66/CF composite system, the length of CF is about 0.5 ~ 0.7mm, the interface between PA66 matrix and carbon fiber is fully combined, and nylon 66 is well wrapped around carbon fiber. The fracture surface of PA66/CF sample is rough, and the PA66/CF composite is a ductile material. Compared with PA66, the mechanical properties of PA66/CF composites are significantly improved.

PA66 Nylon (PA) has a series of excellent properties, such as high mechanical strength, chemical resistance, oil resistance, wear resistance, self-lubrication, easy processing and forming, and has become one of the thermoplastic engineering plastics widely used at home and abroad. But in the practical application, the performance requirements of nylon are different under different conditions or environment. For example, electric drill and motor shell, pump impeller, bearing, diesel engine and air conditioning fan and other parts require nylon material to have high strength, high rigidity and high dimensional stability; Because of the poor toughness of nylon at low temperature, it is necessary to toughen it. In some outdoor applications, nylon materials must be weather-resistant modification in long-term outdoor environment. PA66-LCF Long carbon fiber reinforced nylon has excellent damping properties in 3D printing and has better performance than glass fiber reinforced nylon. In the design of tools for industrial applications, traditional techniques have used aluminum or alternative metal alloys because metal components perform better and meet the requirements of the tool. In many cases, thermoplastics can meet the strength requirements of such tools, but not the rigidity requirements for performing test tasks. Carbon fiber reinforced nylon is an ideal substitute for metal. Due to the combination of the light weight of nylon and the mechanical strength and thermal properties of carbon fiber, the strength and stiffness of carbon fiber composite nylon material is significantly improved, and its mechanical strength even exceeds that of 3D-printed PEEK and PEKK. In the automobile industry, from internal and external components such as vehicle anchors and instruments to engine housing, metal parts can be replaced. As we all know, automotive carbon fiber is widely used in automobile manufacturing due to its strong thermal and mechanical properties. As a substitute for metal parts, carbon fiber reinforced nylon has a wide range of application prospects in the automobile industry, which can realize the possibility of weight reduction and design optimization, as well as environmental protection and economic advantages.
