Carbon fiber (CF) is a new type of fiber material with high strength and high modulus fibers with a carbon content of over 95%. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fibers and undergoing carbonization and graphitization treatment. Carbon fiber is "flexible outside and rigid inside", lighter in weight than aluminum metal, but higher in strength than steel. It has corrosion resistance and high modulus characteristics, and is an important material in national defense, military industry, and civil applications. It not only has the inherent characteristics of carbon materials, but also has the flexibility and processability of textile fibers. It is a new generation of reinforcing fibers. Carbon fiber has many excellent properties, including high axial strength and modulus, low density, high specific properties, no creep, resistance to ultra high temperatures in non oxidizing environments, good fatigue resistance, specific heat and electrical conductivity between non-metals and metals, small coefficient of thermal expansion, anisotropy, good corrosion resistance, and good X-ray transmission. Good electrical and thermal conductivity, good electromagnetic shielding, etc. Compared to traditional glass fibers, carbon fibers have a Young's modulus that is more than three times higher; Compared with Kevlar fiber, its Young's modulus is about twice that of Kevlar fiber, and it is insoluble in organic solvents, acids, and alkalis, with outstanding corrosion resistance. application area Carbon fiber is an important strategic material for the development of national defense, military industry, and the national economy. It is a key technology intensive material. With the academic research from short fiber carbon fiber to long fiber carbon fiber, the technology and products for using carbon fiber to produce heating materials are gradually becoming popular. In the context of rapid industrialization in the world today, the use of carbon fiber is becoming increasingly diverse. Long fibers have been used as a type of high-performance fiber in China. Carbon fiber composites have irreplaceable advantages in situations requiring high temperature and high physical stability. The higher the specific strength of the material, the smaller the dead weight of the component, and the higher the specific modulus, the greater the stiffness of the component. Due to its excellent performance, carbon fiber has a wide application prospect in the fields of national defense and civil use.
