Carbon fiber can be vast application in Engineering
发布时间:2014-4-26 10:25:05 点击量:576

Carbon fiber is a new material with excellent mechanical properties, its steel accounted for less than 1/4, the tensile strength of carbon fiber resin composite material is generally above 3500Mpa, is 7~9 times that of steel,tensile elastic modulus of 23000~43000Mpa is higher in steel. Therefore,the specific strength of CFRP material strength and density can reach 2000Mpa/ (g/cm3) above, the specific strength of A3 steel is only 59Mpa/(g/cm3), the ratio of modulus than steel. Carbon fiber products higher than the strength of the material, the component weight and smaller, higher than the modulus, the component stiffness is bigger, from this sense indicates that the carbon fiber has broad application prospects in engineering, in a variety of new composite materials (such as polymer composites, metalmatrix composites, Tao Ciji composite materials) to the excellent performance, pultrusion equipment many people expected, human beings in the material application is from the iron age into a composite materials have been widely used in the era.

Carbon fiber is inorganic polymer fiber containing carbon content is higher than 90%。 In which the carbon content is higher than that of graphite fiber 99%. Carbon fiber axial strength and high modulus, no creep, fatigue resistance, between heat and electrical conductivity between the metal and nonmetal, small thermal expansion coefficient, good corrosion resistance,low density of fibers, good permeability of X ray. But its poor impact resistance, easy damage, oxidation occurs under the action of the acid, and metal composite will occur when the metal carbide, carburizing and electrochemical corrosion phenomenon. Therefore, the carbon fiber surface treatment shall be carried out before use.
