Carbon Fiber

Dec 20, 2016

Carbon fiber is a carbon content of 95% or more high-strength, high modulus fiber of the new fiber materials. It is made of flaky graphite microcrystal and other organic fibers along the axial direction of the fiber pile, the carbonation and graphitization of the microcrystalline graphite material. Carbon fiber "outside the soft inside just", the quality of aluminum than the light, but the strength is higher than iron and steel, and has a corrosion-resistant, high modulus characteristics of the military and civilian aspects of national defense are important materials. It not only has the inherent intrinsic properties of carbon materials, but also both the softness of textile fibers can be processed, is a new generation of reinforcing fibers.

Carbon fiber has many excellent properties, carbon fiber axial strength and modulus, low density, high specific performance, non-creep, non-oxidizing environment, high temperature resistance, fatigue resistance. Specific heat and conductivity between the non-metallic and metal, thermal expansion coefficient is small and anisotropic, good corrosion resistance, X-ray permeability. Good electrical conductivity and thermal conductivity, good electromagnetic shielding.

Compared with traditional glass fiber, the Young's modulus of carbon fiber is more than 3 times; It compared with Kevlar fiber, Young's modulus is about 2 times its in organic solvents, acids, alkalis insoluble does not expand, corrosion resistance prominent.
