LFT-G Polyamide 12 long carbon fiber reinforced compounds nylon for car parts

Long carbon fiber

Carbon fiber has many excellent properties, high axial strength and modulus, low density, high specific performance, no creep, super high temperature resistance in non-oxidizing environment, good fatigue resistance, specific heat and electrical conductivity between non-metal and metal, small coefficient of thermal expansion and anisotropy, good corrosion resistance, good X-ray transmission. Good electrical and thermal conductivity, good electromagnetic shielding, etc.

Compared with traditional glass fiber, carbon fiber has more than 3 times of Young's modulus; it is about 2 times of Young's modulus compared with Kevlar fiber, which is insoluble and swollen in organic solvents, acids and alkalis, and has outstanding corrosion resistance.

But is there a way to reduce the price of carbon fiber? That is to mix it with relatively cheap nylon material to form a composite material with good performance and meet the requirements. In that case, there is no doubt that carbon fiber nylon will definitely have a place in the composite material.

Nylon itself is an engineering plastic with excellent performance, but moisture absorption, poor dimensional stability of products. Strength and hardness are also far from metal. In order to overcome these shortcomings, as early as before the 70s. People have used carbon fiber or other varieties of fibers for reinforcement to improve its performance. Carbon fiber reinforced nylon materials have developed rapidly in recent years, because nylon and carbon fiber are excellent performance in the field of engineering plastics materials, its compound material synthesis reflects the superiority of the two, such as strength and rigidity than unreinforced nylon is much higher, high temperature creep is small, thermal stability has improved significantly, good dimensional accuracy, wear resistance. Excellent damping, compared with glass fiber reinforced has better performance.

Therefore, carbon fiber reinforced nylon (CF / PA) composites have developed rapidly in recent years. And for 3D printing using SLS technology is the most suitable technical means to achieve carbon fiber reinforced nylon.
