Long glass fiber filler reinforced resin material for molding, injection-molded article molded by injecttion-molding the resin material, and method for molding the resin material

摘要

A long glass fiber filler reinforced resin material for molding includes a matrix polymer comprising a polypropylene component having a pentad isotactic index of at least 95%, and having a melt flow rate (JIS K7210, a temperature of 230 ° C.; and a load of 21.18N) of 100 to 300 g/10 min; a long glass fiber filler in a content of 30 to 50 mass percent with respect to a total mass; an affinity providing component for providing affinity between the matrix polymer and the long glass fiber filler. At least the matrix polymer and the long glass fiber filler form a composite. Thus, breakage of the long glass fiber filler is suppressed during molding processing, so that a molded article having a high bending modulus and a high impact strength can be molded.
