Abstract
A composite material, and a process for its manufacture is described. A film of polypropylene is layered over a textile core of isotactic polypropylene fibers and is fused to thereto by entangled polypropylene interposed between the textile core and the film so as to inhibit stretching of the textile core. The process includes positioning a film of polypropylene over a textile core of isotactic polypropylene fibers, and applying heat under pressure to the film so as to raise a film temperature above a melting point of the film while preventing melting of a crystalline component of the textile core to fuse the film to the textile core by causing entanglement of polypropylene of the textile core with polypropylene of the film so as to inhibit stretching of the textile core. The composite material is used for sailcloth.
