Carbon fiber is an artificial synthetic fiber material with a carbon content of more than 95%. It uses fiber filaments as raw materials and undergoes chemical treatments such as high-temperature carbonization and oxidation.

Finally, a high-performance material is obtained by applying a layer of resin. Carbon fiber has the flexibility of yarn and the strength of carbon elements.

It can be said to be flexible on the outside and rigid on the inside. The strength is even higher than steel, but the weight is lighter than aluminum.
