摘要：
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/m2 and 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/m2 and 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.
