    The application prospects of carbon fiber composites in the automotive field are optimistic
    According to relevant information, BMW will use CFRP (Carbon Fiber Reinforced Plastic) carbon fiber composite materials in its i3 production car in 2013, and its choice is a slightly lower grade industrial-grade CFRP material, and the cost can be controlled by traditional carbon fiber materials. About half of it.

    Rapid growth in demand, the era of carbon fiber is coming
    As a fibrous carbon material, carbon fiber has a carbon content of more than 90%. The material is black, hard, and has the characteristics of high strength and light weight. The specific gravity of carbon fiber is less than 1/4 of that of steel. The tensile strength of carbon fiber resin composites is generally above 35,000 MPa (MPa), which is 7.9 times that of steel. The tensile modulus of elasticity is 230,000-430,000 MPa, which is higher than that of steel.

    Material introduction of tantalum carbide
    Metal matrix composites have received extensive attention from scientists in the field of materials of various countries due to their unique advantages of high specific strength, high specific modulus, wear resistance and high temperature resistance. At present, the research on metal matrix composite materials is mainly focused on the overall uniform composite, but because the wear only occurs on the surface of the part, the overall composite is not conducive to the recovery and reuse of the material and causes pollution to the environment. On the other hand, many studies have shown that wear-resistant materials need to have both high hardness and high toughness, while the overall composite only improves the hardness, but cannot improve the toughness, while the metal-ceramic composite material maintains the high hardness and high toughness of ceramics. Excellent performance such as wear resistance, and high toughness and high ductility of the metal matrix.
