Carbon fiber (CF) refers to high strength and high modulus fiber with carbon content of more than 90%. It is formed by cracking and carbonizing organic fibers (viscose based, asphalt based, polyacrylonitrile based fibers, etc.) in high temperature environment.
High performance carbon fiber has a series of excellent properties that can not be replaced by other materials, such as light weight, high strength, high modulus, high temperature resistance, corrosion resistance, erosion resistance and sputtering, good designability and composability. It is an indispensable strategic emerging material for sophisticated weapons and equipment such as rockets, satellites, missiles, fighters and ships.
As a strategic new material with excellent properties, carbon fiber has less than 1 / 4 of the density and 5-7 times the strength of steel. Compared with aluminum alloy structural parts, the weight reduction effect of carbon fiber composites can reach 20% – 40%; Compared with steel metal parts, the weight reduction effect of carbon fiber composites can reach 60% – 80%.
