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.

Polyamide 66 roving carbon fiber Nylon black color with heat resistance

PA66 carbon fiber conductive plastic reinforced nylon plastic material, which combines the electrical conductivity of metal (a voltage applied to both ends of the material, through the material through the current) and the various properties of plastic (that is, material molecules are composed of many small, repeated structural units).Density (g/cm3) : 1.2 ~ 1.7, conductive anti-static plastic shielding efficiency (30MHz-10GHz) : 60-85dB;, mainly used in electronics, integrated circuit packaging, electromagnetic shielding and other fields.It is an important type of conductive polymer materials.Conductive anti-static material Semi-conductive shielding material used in medium and high voltage cables.Conductive plastic is a kind of functional polymer material which mixes resin and conductive material and is processed in the way of plastic.Conductive anti-static plastic product density is low, the weight is reduced by 50%;Bending modulus (MPa) : 2400 ~ 6000. With the increase of carbon fiber content, the tensile strength, flexural strength and flexural elastic modulus of the composites all increase.The impact strength of the cantilever beam increases first and then decreases, and the impact strength reaches its maximum value when the carbon fiber mass fraction is 30%, which is. The reason is that when the fiber content is relatively large, the fracture stress and its energy threshold increase, and the absorption methods such as elongation of fracture path caused by avoiding fiber, demonding of fiber-matrix interface and fiber pull-out are added, while the internal notching effect of fiber increases slowly, thus increasing the impact strength.When the mass fraction of carbon fiber is more than 30%, the internal notching effect of carbon fiber increases with the increase of carbon fiber content, and the impact strength decreases.
