Carbon fiber is a new type of fiber material with a carbon content of more than 95%, high strength and high modulus. The quality of carbon fiber is lighter than that of aluminum, but the strength is higher than that of steel, and it has the characteristics of corrosion resistance and high modulus. It is an important material with excellent mechanical properties in national defense and civil use. In the Chinese patent with application number 202210451271.3, a carbon fiber bicycle wheel with shock absorption function is disclosed, which belongs to the field of bicycles.
