Problems solved by technology

[0004] Since the existing technology is thermosetting molding of fibers and resins, the tensile strength and elastic modulus of the products are low, and the production cost is high, which does not fully play the most ideal role. Some key projects and fields still use traditional metal materials, which are easy to corrode. , heavy quality, high operating cost, high labor intensity and other disadvantages
