ABSTRACT:
Described are smooth, glossy finished fiber reinforced thermoplastic prepreg materials composed of reinforcement fibers impregnated with and surrounded by thermoplastic. Prior to consolidation, the material preferably consists of thermoplastic fibers and reinforcing fibers, intimately blended together. When heated, with the aid of pressure, the thermoplastic fibers melt, surround and impregnate the reinforcing fibers and provide a smooth, glossy finish to the reinforced article. Excellent surface appearance and the ability to accommodate high-speed processing characterize the prepreg materials of this invention.
