THERMOPLASTIC RESIN-REINFORCED SHEET MATERIAL, REINFORCED THERMOPLASTIC-RESIN MULTILAYER SHEET MATERIAL, METHOD FOR PRODUCING THE SAME, AND MULTILAYER THERMOPLASTIC-RESIN-REINFORCED MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a high-quality reinforced thermoplastic-resin multilayer sheet material having excellent mechanical properties and drapeability in which a thermoplastic resin excellent in recycling efficiency and shock resistance is used as a matrix; a method for efficiently producing the reinforced thermoplastic-resin multilayer sheet material in a short time; and a high-quality multilayer thermoplastic-resin-reinforced molding molded using the reinforced thermoplastic-resin multilayer sheet material.

SOLUTION: This thermoplastic-resin-reinforced sheet material 2 is formed by attaching reinforcing-fiber sheet material 3 formed of a plurality of reinforcing fibers 3f arranged in a predetermined direction in a sheet-like structure on both surfaces of a thermoplastic-resin sheet material 4. This reinforced thermoplastic-resin multilayer sheet material is formed by stacking the thermoplastic-resin-reinforced sheet materials 2, and stitched and integrated with an integration thermoplastic-resin fiber bundle composed of the same material as the thermoplastic-resin sheet material 4. The reinforcing-fiber sheet materials 3 are stacked such that their reinforcing directions are multiaxial.
