LFT-G PA66 Nylon66 composé de fibre de carbone longue moulage par injection de 20% à 60% plus performant

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.
