METHOD FOR MANUFACTURING COMPOSITE RODS

摘要

The method involves inserting a portion of a mandrel in a cylindrical part of each of end pieces having an insert, and placing driving bits (20) at a free end of another portion (19b) of the mandrel. Resin pre-impregnated fibers (16) are wound onto an outer surface of an assembly consisting of an inner body (18), the end pieces and the latter portion free from the bits. An outer body is formed by the fibers. The inner body and an outer body are polymerized to form an integral body after removing the bits. The mandrel is removed, and the integral body is cut into required length. The end pieces are made of metallic material, high resistance plastic material or carbon. The pre-impregnated fibers are made of carbon. The insert is made of a metallic material. The connecting rod is made of a composite material.
