Reinforced thermoplastic-resin multilayer sheet material

A thermoplastic-resin-reinforced sheet material formed of a plurality of narrow, having a width in a range of 1 mm-20 mm, thermoplastic-resin-reinforced sheet materials arranged in a width direction, the plurality of narrow, having a width in a range of 1 mm-20 mm, thermoplastic-resin-reinforced sheet materials each formed by joining a narrow, having a width in a range of 1 mm-20 mm, reinforcing-fiber sheet material, including a plurality of reinforcing fibers arranged in a predetermined direction, to both surfaces of a narrow, having a width in a range of 1 mm-20 mm, thermoplastic-resin sheet, wherein a material of the thermoplastic-resin sheet serves as matrix, only a surface layer portion of the reinforcing-fiber sheet material being impregnated with the material of the thermoplastic-resin sheet,

• wherein the cross-sectional thickness of each reinforcing-fiber sheet material is set greater than two times the diameter of each reinforcing fiber and set within ten times the diameter of each reinforcing fiber,
• wherein the thermoplastic-resin sheet material is bonded to the entirety or several portions of one surface of the reinforcing-fiber sheet material by thermal adhesion,
• wherein the reinforcing-fiber sheet material is formed from multi-filament formed by continuously spreading, in a width direction, a reinforcing fiber tow including a plurality of filament-type reinforcing fibers bundled together, and
• wherein the reinforcing-fiber sheet material is formed of a plurality of reinforcing fiber tows, each including a plurality of reinforcing fibers bundled together with a sizing agent so as not to be unraveled, arranged in a sheet-like structure.
