ABSTRACT:
A method of manufacturing a fiber-reinforced thermoplastic resin of cellular structure comprises immersing bundles of filaments of fibrous reinforcing material in a bath containing an emulsion of thermoplastic resin added with a blowing agent, drying the emulsion-impregnated reinforcing filaments, preheating the dried reinforcing filaments, compressing the preheated reinforcing filaments to provide an integrally bonded block of fiber-reinforced thermoplastic resin, and allowing the block to expand. The fiber-reinforced thermoplastic resin of cellular structure is advantageously employed as a light-weight, high strength construction material.
