ABSTRACT:
A thermoplastic composite having a plurality of layers of material each having a particular total thickness and a particular total volume, including a first layer of thermoplastic resin materal forming a core. At least two layers of fabric material each disposed on an opposite side of the first layer and impregnated with the core material to define an outer skin on the core. Two layers of thermoplastic resin material each overlaying one of the at least two layers of fabric and each bonded to the thermoplastic material impregnated in the adjacent layer of fabric material to define an outer covering for protecting the layers of fabric and providing a covering for protecting the layers of fabric and providing a smooth exterior. The thickness of the core forming a substantial percentage of the total thickness of the composite and the fiber volume of the at least two layers of fabric material forming less than one third (1/3) of the total volume of the composite.
