摘要：
A thermoplastic thermoformable composite material for shaping and stretching into a desired form without voids and holes, including a core formed by at least one layer of chopped fibers enveloped and impregnated by thermoplastic material to form a fabric layer. Layers of thermoplastic material respectively positioned on opposite sides of the fabric layer core, and the layers of thermoplastic material provided with a sufficient thickness to flow into and heal any voids or holes formed in the core as the composite material is shaped and stretched into a desired form.
