Fiber reinforced composites using the waste cord of synthetic fibers as the matrix material were molded by injection molding. The waste cord of polyester and nylon 6 fabrics having thermoplastic characteristics was fed into the molding machine directly together with the reinforcements in order to simplify the molding process. Glass and carbon fibers were used as the reinforcements and the reinforcement content was varied for the experiments.
The tensile strength and modulus of the composites were much larger than those for the matrix material, and increased with increasing reinforcement content. It is concluded that the molding system devised here is effective for the recycle of the waste cord of synthetic fibers.
