Method of making a layered carpet construction suitable for use for the automotive industry as a 'deck lid' wherein the backing of the carpet construction is specially processed to adhere to the backside of the exposed carpet face and a separate layer of foamed material is then secured to the backing.

Automotive deck lid piece

Fiber reinforced thermoplastic molded products, sheets, and the like, having a glossy surface are produced by intimately blending discrete reinforcing fibers (e.g. fiberglass) and thermoplastic fibers (e.g. polypropylene or polycarbonate) into a web. The web is heated to the melting point of the thermoplastic fibers while applying pressure, to eliminate air and press the web into a consolidated structure. Breakage of the reinforcing fibers is minimized by limiting the thickness of the web and limiting the pressure so as to produce a consolidated structure with minimal fiber breakage and a Notched Izod of at least one. Layered consolidated structures, some without reinforcing fibers, may be heated and pressed together to form a final structure having a thickness greater than the individual structures. The great majority of the fibers are provided so that the fibers of each type are within the range of about 0.5-5 inches. A sheet capable of replacing an automotive metal panel (that is having sufficiently high gloss, rigidity and impact characteristics) is provided, the sheet having Notched Izod of at least about two and preferably at least about five. Products with Notched Izods of up to eight or nine may be achieved.

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.
