The maximum advantages of carbon fiber products include low density and light weight, as well as the tensile strength far above the steel, 3,000mpa or more. Moreover, carbon fiber pipe also has the exnt performance such as corrosion resistance, creep resistance, high temperature resistance. However, carbon fiber pipe has an obvious shortcoming, and that is, it has the conductivity. Therefore, it is not suitable for the occasion of the transmission of electricity or electric components.
