It's OK. Carbon fiber is a microcrystalline graphite material obtained by carbonizing and graphitizing organic fibers. The microstructure of carbon fiber is similar to artificial graphite, which is a turbostratic graphite structure.
Carbon fiber is a new material with excellent mechanical properties. Its specific gravity is less than 1/4 of that of steel. The tensile strength of carbon fiber resin composite materials is generally above 3500Mpa, which is 7~9 times that of steel. The tensile elastic modulus is 23000~43000Mpa, which is also higher than that of steel.
Therefore, the specific strength of CFRP, that is, the ratio of the strength of the material to its density, can reach more than 2000Mpa/(g/cm3), while the specific strength of A3 steel is only about 59Mpa/(g/cm3), and its specific modulus is also higher than that of steel.
