From the fishing rod, tennis racket in daily life to the high-end fields such as aircraft and rockets, carbon fiber composites can be said to be everywhere. So, how much do you know about carbon fiber composites?
In the early 50s, in order to meet the needs of advanced science and technology such as rocket, aerospace and aviation, China began to develop carbon fibers. By the early 80s, high performance and ultra high performance carbon fibers were emerging. In recent years, China has increasingly intensified its R & D, production and application of carbon fiber composite materials.

Carbon fiber is a kind of special fiber mainly composed of carbon elements. The carbon content of carbon fiber is different, but in general, the carbon content is more than 90%. Carbon fiber has the characteristics of general carbon material, such as high temperature resistance, abrasion resistance, conduction, heat conduction and corrosion resistance. At the same time, carbon fiber is also a new material with excellent mechanical properties: its specific gravity is less than 1/4 of steel, and the tensile strength of carbon fiber resin composite is generally above 3500Mpa, it is 7~9 times of steel and tensile elasticity. The modulus is 23000~43000Mpa and the steel is higher than that of steel.
Carbon fiber is a new nonmetallic material. Carbon fiber composites have excellent properties such as high strength, high temperature resistance, corrosion resistance, fatigue resistance, creep resistance, conductivity, heat transfer, small specific gravity, and small thermal expansion coefficient. Carbon fiber is mainly used for its heat resistance, corrosion resistance, conductivity and other properties.
Nowadays, carbon fiber composites have been widely used in sports equipment, textile, chemical machinery and medicine.
