TUBULAR BODY AND ITS MANUFACTURE

摘要

PURPOSE: To provide a tubular body of high strength and superior durability and also provide its manufacturing method without damaging the design for reducing the weight. CONSTITUTION: In a tubular body, in which a prepreg composed of high strength fiber impregnated with a synthetic resin is wound and a reinforced layer 16 thinner than a main body layer composed of high strength fiber mainly oriented almost in the circumferential direction on the inner peripheral side of a main body layer 14 mainly oriented in the axial length direction is formed, a given thin film 18 composed mainly of thermosetting and thermoplastic synthetic resin is heat molded integrally with the reinforced layer 16 on the further inner side of the innermost surface of the reinforced layer formed by the prepreg.
