繊維強化複合材料のマトリックスとしてのPP不織布裁断屑のリサイクル手法 Recycle Technique for PP Cut Waste of Nonwoven Fabrics as Matrix Material for Fiber Reinforced Composites
A recycle technique for cut waste of polypropylene (PP) nonwoven fabrics as a matrix material for fiber reinforced thermoplastic composites was investigated. Glass and carbon fibers were selected as representative reinforcements and thermoplastic composites were molded using a simple injection molding method. The effects of surface treatment of the reinforcements on tensile modulus and strength of molded composites were discussed based on SEM observation results of fracture surfaces. Moreover, spun maleic anhydride grafted PP was fed into the injection machine together with the waste PP and reinforcements as a binder. The results suggest that the injection molding method described herein shows promise for contributing toward the material recycling of waste products of PP nonwoven fabrics.
