Patent number: 5098624Abstract: 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.Type: GrantFiled: October 31, 1990Date of Patent: March 24, 1992Assignee: C.H. Masland & SonsInventors: Rayna W. Smith, Gerald W. Miller

Patent number: 4950439Abstract: 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.Type: GrantFiled: July 10, 1987Date of Patent: August 21, 1990Assignee: C. H. Masland & SonsInventors: Rayna W. Smith, Glen W. Saidla

Patent number: 4835030Abstract: A process for applying a PVC heel pad to automotive carpeting to eliminate the necessity of pre-forming the heel pads before they are applied to the carpet and the products formed thereby, including the steps of applying a hot melt adhesive composition between the carpet and the back side of an unpatterned PVC sheet; positioning the composite which includes the carpet, adhesive and unpatterned PVC sheet in a metallic heel pad patterned mold; and forming in situ a pattern molding on the PVC pad simultaneously with the adhesion of the PVC pad to the carpet.Type: GrantFiled: October 14, 1987Date of Patent: May 30, 1989Assignee: C. H. Masland & SonsInventors: William H. Squier, Dennis E. Hair

Patent number: 4230755Abstract: A flat unitary composite carpet structure which can be hot molded permanently into non-planar shapes conforming to contoured surfaces such as automobile floors has an exposed textile surface to the underside of which is adhered a relatively thick layer of polyurethane foam which provides good fiberbonding, tuftbinding and sound deadening qualities to the composite carpet structure, and to the underside of the polyurethane foam layer is adhered a relatively thin layer of polyethylene which provides good shape retention qualities to the composite carpet structure and provides means for adhesively attaching an underpad to the carpet structure as the latter is hot molded to conform to the desired contoured shape.Type: GrantFiled: November 23, 1976Date of Patent: October 28, 1980Assignee: C. H. Masland & SonsInventor: Robert W. Morris
