Abstract
PURPOSE: To obtain a molded product excellent in shock resistance by a method wherein glass fibers in a specified sheet form are inserted between two thermoplastic resin stamp-molding materials with comparatively long glass fibers and laminated into a unitary body.
CONSTITUTION: Two thermoplastic resin stamp-molding materials, at least in one of which 5W40wt%, preferably, 20W30wt% of glass fibers 2cm or more long, preferably, comparatively long glass fibers 5cm or more long are contained, are heated and between these two molding materials is inserted a glass fiber sheet having a unit weight of 600g/m2 or less, preferably, 300W600g/m2 and a restitution force of 50kg/cm2 or less, preferably, 10W30kg/cm2. Then, this laminate is placed between a set of molds composed of a upper and an lower mold, molded under a pressure of 100W200kg/cm2 and laminated into a unitary body.
