　　Carbon fiber is a kind of carbon fibrous material. It is a kind of strength is greater than steel, lower density than aluminum, than than stainless steel corrosion resistant, heat resistant steel and high temperature resistant, can like copper conductive again, has many valuable electrical, thermal and mechanical properties of new material. Made of carbon fiber and plastic composite material of aircraft not only light, and low power consumption, large thrust, low noise; With carbon fiber system computer disk, which can improve the storage capacity and computing speed of the computer; Make the satellite and the rocket with carbon fiber reinforced plastic space vehicles, such as high mechanical strength, the quality is small, can save a lot of fuel.
