1. Carbon fiber is replacing steel in certain situations. Its specific gravity is less than 1/4 of steel. The tensile strength of carbon fiber resin composite materials is generally above 3500Mpa, which is 7 to 9 times that of steel. The tensile elastic modulus is 23000 to 43000Mpa, which is also higher than steel.
2. Carbon fiber has many excellent properties. Carbon fiber has high axial strength and modulus, low density, high specific performance, no creep, ultra-high temperature resistance in non-oxidizing environment, good fatigue resistance, and Thermal and electrical conductivity are between non-metals and metals. The thermal expansion coefficient is small and anisotropic. It has good corrosion resistance and good X-ray transmittance. Good electrical and thermal conductivity, good electromagnetic shielding, etc.
