A composite thermoplastic sheet includes, in an exemplary embodiment, a permeable core layer having a first surface and an opposing second surface. The core layer includes a plurality of reinforcing fibers bonded together with a first thermoplastic material. The composite sheet also includes a flexible thermoplastic skin laminated to and covering at least a portion of the first surface of the core layer. The core layer includes about 20 weight percent to about 80 weight percent reinforcing fibers.

What is claimed is: 1. A composite thermoplastic sheet comprising: a permeable core layer comprising a plurality of reinforcing fibers bonded together with a first thermoplastic material, said core layer having a first surface and an opposing second surface, and comprising about 20 weight percent to about 80 weight percent reinforcing fibers; and a flexible elastomeric skin laminated to and covering at least a portion of said first surface of said core layer, said portion of said first surface of said core layer covered by said flexible elastomeric skin defining a hinge area, said flexible elastomeric skin comprising an elastomeric material having a tensile modulus less than about 2500 Mpa and a tensile elongation of greater than about 50 percent before failure. 2. A composite thermoplastic sheet in accordance with claim 1 further comprising a flexible skin laminated to and covering at least a portion of said second surface of said core layer. 3. A composite thermoplastic sheet in accordance with claim 1 wherein said first thermoplastic material is selected from the group consisting of polyolefins, polyamides, polystyrene, acrylonitrylstyrene, butadiene, polyesters, polybutyleneterachlorate, polyvinyl chloride, polyphenylene ether, polyphenylene oxide, polyether imide, polycarbonates, polyestercarbonates, acrylonitrile-butylacrylate-styrene polymers, polybutyleneterephthalate, polyethyleneteraphthalate, amorphous nylon, and mixtures thereof. 4. A composite thermoplastic sheet in accordance with claim 1 wherein said elastomeric is material selected from the group consisting of thermoplastic elastomers, thermoplastic urethanes, silicones, polypropylene, polyethylene, polycarbonates, and mixtures thereof. 5. A composite thermoplastic sheet in accordance with claim 1 further comprising at least one decorative outer layer. 6. A composite thermoplastic article formed from a composite thermoplastic sheet having a hinge area, said composite thermoplastic article comprising; a permeable core layer comprising a first thermoplastic material and a plurality of reinforcing fibers, said core layer having a first surface and an opposing second surface; and a hinge area comprising a first flexible elastomeric skin laminated to at least a portion of said first surface of said core layer, said first flexible elastomeric skin comprising an elastomeric material having a tensile modulus less than about 2500 Mpa and a tensile elongation of greater than about 50 percent before failure. 7. A composite thermoplastic article in accordance with claim 6 wherein said hinge area further comprises a second flexible elastomeric skin laminated to at least a portion of said second surface of said core layer, said second flexible elastomeric skin aligned with said first flexible elastomeric skin, said second flexible elastomeric skin comprising said elastomeric material. 8. A composite thermoplastic article in accordance with claim 6 wherein said first thermoplastic material is selected from the group consisting of polyolefins, polyamides, polystyrene, acrylonitrylstyrene, butadiene, polyesters, polybutyleneterachlorate, polyvinyl chloride, polyphenylene ether, polyphenylene oxide, polyether imide, polycarbonates, polyestercarbonates, acrylonitrile-butylacrylate-styrene polymers, polybutyleneterephthalate, polyethyleneteraphthalate, amorphous nylon, and mixtures thereof. 9. A composite thermoplastic article in accordance with claim 6 wherein said elastomeric material is selected from the group consisting of thermoplastic elastomers, thermoplastic urethanes, silicones, polypropylene, polyethylene, polycarbonates, and mixtures thereof. 10. A composite thermoplastic article in accordance with claim 6 further comprising at least one decorative outer layer. 11. A composite thermoplastic article in accordance with claim 6 wherein said core layer comprises about 20 weight percent to about 80 weight percent reinforcing fibers. 12. A composite thermoplastic article in accordance with claim 6 wherein said core layer has a density of about 0.2 gm/cc to about 1.8 gm/cc. 13. A composite thermoplastic article in accordance with claim 1 wherein said core layer has a density of about 0.2 gm/cc to about 1.8 gm/cc.
