A long-fiber-reinforced thermoplastic resin sheet comprises short strands, each of which has a width of from 0.2 to 5 mm and a length of from 10 to 150 mm and is made of a unidirectionally long-fiber-reinforced thermoplastic resin. The short strands are oriented at random and are fixed together at intersections thereof. The long-fiber-reinforced thermoplastic resin sheet has a basis weight of from 30 to 500 g/mand is provided with openings therein. The long-fiber-reinforced thermoplastic resin sheet can be produced by evenly spreading and piling up short strands of substantially circular or elliptical sections, and subjecting the short strands to pressureless hot-melt adhesion or to hot-melt compression bonding under pressure such that the sheet has a basis weight of from 30 to 500 g/mand is provided with openings therein. The short strands of the substantially circular or elliptical sections have an average diameter of from 0.1 to 1.5 mm and an average length of from 10 to 150 mm, and are made of a unidirectionally long-fiber-reinforced thermoplastic resin.

Long-fiber-reinforced thermoplastice resin sheets, production process thereof, and composite structures reinforced by the sheets

A formed lining for a vehicle comprises a multi-layered base member comprising a film-like hot melt adhesive on a front thereof and a top cover member comprising a web-like hot melt adhesive on a back thereof, wherein the top cover member is bonded to the multi-layered base member. The top cover member and the heated multi-layered base member are set in a forming die. The hot melt web on the top cover member is melted by heat of the multi-layered base member during a forming process. Then, the top cover member is bonded to the multi-layered base member to be formed simultaneously.
