ABSTRACT OF THE DISCLOSURE Reinforced thermoplastic polymer composite sheets, formable into smooth, shaped objects in a stamping process. The composite sheet is produced by laminating together (1) a first layer of thermoplastic resin containing short glass fibers and a mineral filler such as kaolin, (2) a backing reinforcing layer comprising a long glass mat impregnated by thermoplastic resin and (3) optionally a third layer similar to said first layer. The long glass mat is positioned within the reinforcing layer during impregnation, whereby the mat becomes encased in a resin matrix.
