MECHANICAL BEHAVIOR OF POLYOLEFIN COMPOSITES USING WASTES OF FIBROUS MATERIAL AS MATRIX AND REINFORCEMENT

摘要

The thermoplastic composites were molded by using the cut waste of non-woven polypropylene fabric as matrix material. The waste cords of cotton, nylon6 and cut waste of rayon were also used as reinforcements. Simple injection molding method was proposed here. Namely, those wastes were fed into the injection molding machine directly together with the matrix material. It is concluded here from the tensile tests that the wastes of cotton and rayon with good dispersion during the molding process are effective for the reinforcements of the thermoplastic composites. Waste cord of nylon6 is not, however, good for reinforcement because of its poor dispersion.
