carbon-fiber is a new type material which has supreme mechanical characteristics, such as high tensile-strength, high elastic-modulus, anti-high temperature wear-resistance, anti-corruption, fatigue resistance, resisting creep, electric conductivity, heat resistance and low thermal expansion coefficient, etc. It can be applied in aerospace, aviation, industrial field, architecture, and sporting, recreational goods. The uses of Carbon-fiber have changed our have changed our life style and are increasing our living quality.

The performance of the carbon-fiber is better than metal material; its tensile strength is 3-4 times higher than steel, fatigue strength is 2 times higher than steel, weight is 3-4 times lighter than steel, thermo-coefficient of expansion is 4-5 times less than steel. The development of carbon-fiber has a wide and application space.
