What Material Is Carbon Fiber?

Carbon fiber is a high-performance fiber material with a carbon content of more than 90%.
Carbon fiber is mainly made from organic matrix fibers such as polyacrylonitrile (PAN), asphalt, viscose, etc., which are processed at high temperatures and usually carbonized in an inert gas environment above 1000 degrees Celsius. In this process, most non-carbon elements are removed. Carbon fiber has the characteristics of high strength, high modulus, high-temperature resistance, friction resistance, good thermal and electrical conductivity, and corrosion resistance. It has high tensile strength and low density. Compared with metal materials, it is light in weight and high in strength. Compared with plastic products, it has extremely high strength. The microstructure of carbon fiber is similar to artificial graphite, which is a turbostratic graphite structure. Due to its excellent mechanical properties, carbon fiber is widely used in high-end products, such as aerospace, sporting goods, and other fields that require lightweight and high-strength materials.
