COMBINING FIBERS AND THERMOPLASTIC FILMS BY A CHEMICAL ADHESIVE

摘要

??stract of the Disclosure This invention relates to the production of composite materials, and, more particularly to the production of strips of fibrous and thermoplastic materials which may then be combined in layers for subsequent molding under selected pressure and temperature conditions to form a composite product. A thin composite strip or tape or sheet of thermoplastic material is united with reinforcing fibers by a chemical addition at room temperatures. With such a procedure, the formed strip may be handled and easily "laid up" in successive layers in a mold prior to coalescing the composite under suitable temperature and pressure conditions.
