Patent number: 7264685Abstract: The present invention relates to a composite shoddy for use in a vehicle interior. To this end, the composite shoddy of the present invention includes an organic material having a predetermined density defining shoddy bottom layer and a scrim material having a predetermined density defining a scrim top layer. The scrim top layer is adapted to operatively engage a surface material and accommodate movement of a surface material in the shear direction. The composite shoddy further includes a bituminous mastic material having a predetermined density defining a mastic middle layer. The mastic middle layer is disposed between the shoddy bottom layer and the scrim top layer.Type: GrantFiled: December 30, 2003Date of Patent: September 4, 2007Assignee: International Automotive Components Group North America, Inc.Inventors: Jean-Jacques Katz, Kenneth R. Parrish, Theodore J. Peterson, Barry R. Wyerman

Publication number: 20040076786Abstract: A self-adhering, multi-layer composite membrane for sealing a substrate and providing waterproof integrity to the substrate. The composite membrane includes: a surface layer of metal or of a polymeric material to interface the environment; a polyolefin film having a top surface and a bottom surface bonded to the surface layer by an adhesive at its top surface; a waterproof, asphalt-based layer adhered to the polyolefin film; a reinforcing mat having a top surface and a bottom surface, the top surface of which is adhered to the waterproof, asphalt-based layer; a second waterproof, asphalt-based layer adhered to the bottom surface of the reinforcing mat which is adapted to sealingly adhere to the substrate; and a polyolefin release film on the bottom surface of the waterproof asphalt-based adhesive layer to prevent adhesion between the asphalt-based adhesive layer and the surface layer when the composite is wound into a spiral roll.Type: ApplicationFiled: December 3, 2003Publication date: April 22, 2004Applicant: BUILDING MATERIALS INVESTMENT CORPORATIONInventors: Michael P. Naipawer, Adem Chich, Murray S. Sherman
