  • Publication number: 20060246799
    Abstract: Sound attenuating laminates for use within vehicles are provided that include a substrate and polyurethane attached to selected portions of the substrate. The polyurethane is non-porous and serves as a barrier to attenuate sound passing through the substrate. Additional non-porous polyurethane may be added to one or more selected portions of the polyurethane layer to enhance sound attenuation characteristics in the one or more selected portions. Sound attenuating laminates for use within vehicles are provided that include a substrate and breathable polyurethane attached to selected portions of the substrate. The polyurethane serves as an absorber of sound (e.g., sound generated within a vehicle compartment). Additional breathable polyurethane may be added to one or more selected portions of the polyurethane layer to enhance sound absorption characteristics in the one or more selected portions.

  • Patent number: 7017250
    Abstract: Vehicle cockpit assemblies and methods of installing same within vehicles are provided. A vehicle cockpit assembly includes a dash insulator that is configured to be attached to a vehicle firewall, an instrument panel attached to the dash insulator, and a floor covering also attached to the dash insulator. A plurality of apertures are formed through the dash insulator, each of which is configured to overlie a respective opening in a vehicle firewall when attached thereto. Each aperture is configured to sealably receive an item extending therethrough such that substantially no gaps exist between the item and the substrate. Polyurethane may be added to one or more selected portions of the dash insulator to reflect and/or absorb sound.

  • Patent number: 6971475
    Abstract: Vehicle trim components are formed by applying a layer of material onto a mold surface and then selectively applying foam prior to molding operations. Selectively applying foam may include applying foam of different densities in multiple locations and/or applying foam of different thicknesses in multiple locations. The material and foam are subjected to conditions within the mold to produce a trim component having a desired shape. Once de-molded, barrier material may be added and various post-molding operations may be conducted.

  • Publication number: 20040110438
    Abstract: Acoustical panels and methods of making acoustical panels are provided. Isocyanate binder and scrap material are blended together to produce a mixture of recycled material. The mixture of recycled material is formed into a panel, molded to form an acoustic article having a three dimensional contour, and cured via steam. The acoustic article is subjected to trimming operations, and one or more surfaces of the acoustic article may be covered with one or more layers of material. Scrap material generated by the trimming operations are then returned to for reuse.
