Plastic based laminates comprising a fiber reinforced plastic lofted core and outer parallel sheets of thermoset resin impregnated cotton liner paper

摘要

A light weight, high strength laminate having improved fire resistant characteristics and the method of making the same. A preferred embodiment includes a low density fiber reinforced thermoplastic resin core between two parallel sheets of high density fiber reinforced thermoset resin. Another embodiment includes a core of polymeric foam laminated between two parallel inner fiber reinforced thermoplastic resin layers each of which face an outer layer of fiber reinforced thermoplastic resin.
