  • Patent number: 11926137
    Abstract: A composite foam article is disclosed herein. The composite foam article comprises a polyurethane foam core presenting a first surface and a second surface facing opposite the first surface. A first skin is disposed on the first surface and a second skin is disposed on the second surface. The polyurethane foam core has a density of 15-80 kg/m3. The first and second skins comprise a plurality of fibers and a polymeric binder. The composite foam article has a weight per unit area of 500-1000 g/m2 and a strength of greater than 17 N at a post-compression thickness of greater than 2 mm when tested in according with SAE J949 at 23° C.

  • Publication number: 20220032576
    Abstract: A composite foam article comprises a foam core layer presenting a first surface and a second surface facing opposite the first surface. A first polymeric bonding layer is disposed on the first surface, one or more first reinforcing layers comprising a plurality of fibers and a polymeric binder are disposed on the first polymeric bonding layer, and a first polymeric containment layer is disposed on the one or more first reinforcing layers. A second polymeric bonding layer is disposed on the second surface, one or more second reinforcing layers comprising a plurality of fibers and a polymeric binder are disposed on the second polymeric bonding layer, and a second polymeric containment layer is disposed on the one or more second reinforcing layers. At least one catch layer comprising particles of carbon is dispersed in and/or disposed between any of the aforementioned layers.

  • Patent number: 8282147
    Abstract: A laminate product particularly useful in vehicular applications is described. The laminate product comprises a foam core having a first major surface and a second major surface. One or both of the major surfaces comprises a fibrous layer and an adhesive layer adhering the fibrous layer to the foam core. The process for producing the laminate product involves exposing an initial laminate product to infrared radiation. A portion of the adhesive layer between fibers in fibrous layer being ablated. The foam laminate product has improved sound absorption properties and while maintaining desirable strength and stiffness properties. In addition, in certain cases, the peel strength of the fibrous reinforcing layer to the foam core is significantly improved in the present foam laminate product compared to the conventional approaches.
