Carbon fiber is mainly a special fiber composed of carbon elements, and its carbon content varies with different types, generally more than 90%. Carbon fiber has the characteristics of general carbon materials, such as high temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance, etc., but unlike general carbon materials, its shape has significant anisotropy, softness, can be processed into various fabrics, and shows high strength along the fiber axis. Carbon fiber has a small specific gravity and therefore has a high specific strength.
Carbon fiber is made of man-made chemical fibers with high carbon content and non-melting in the heat treatment process, through heat-stabilized oxidation treatment, carbonization treatment and graphitization process.
Carbon fiber detail diagram carbon fiber is a new material with excellent mechanical properties, its specific gravity is less than 1/4 of steel, the tensile strength of carbon fiber resin composite materials is generally more than 3500Mpa, which is 7~9 times that of steel, and the tensile elastic modulus is 23000~43000Mpa, which is also higher than 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.
