Abstract
A liner/insulator includes a pad of fibrous material having a lofty, acoustically insulating portion and a relatively higher density skin along a first face thereof that may function as a water barrier. The acoustical liner is a non-laminate made from polyester, polyethylene, polypropylene, polyethylene terephthalate, glass fibers, natural fibers and any mixtures thereof. For certain applications the liner/insulator may incorporate a facing on one or even two opposing faces thereof. A method of insulating a door including an exterior body panel and an interior fascia panel as well as a door for a vehicle are also provided.
Claims28
A liner, comprising:
- a pad of fibrous material having a lofty, acoustically insulating portion having a density of between substantially 8.0-80.0 kg/m3 and a relatively higher density skin along a first face thereof, said skin having a thickness of between substantially 0.25-10.0 mm and a density of between substantially 32.0-1600.0 kg/m3, said fibrous material being selected from a group consisting of (a) thermoplastic polymer staple fibers and thermoplastic bicomponent fibers, (b) glass staple fibers and thermoplastic bicomponent fibers and (c) a combination of (a) and (b).
An acoustical liner with integral water barrier, comprising a nonlaminate pad of fibrous material having a lofty, acoustically insulating portion having a density of between substantially 8.0-80.0 kg/m3 and a relatively higher density, water-barrier skin along a first face thereof, said skin having a thickness of between substantially 0.25-7.5 mm and a density of between approximately 32.0-1600.0 kg/m3.
A door for a vehicle, comprising:
- an exterior body panel;
- an interior fascia panel connected to said exterior body panel and defining a cavity between said exterior body panel and said interior fascia panel;
- and
- a nonlaminate pad of fibrous material having a lofty, acoustically insulating portion having a density of between substantially 8.0-80.0 kg/m3 and a relatively higher density skin along a first face thereof, said skin having a thickness between substantially 0.25-7.5 mm and a density of between approximately 32.0-1600.0 kg/m3.
The door of clam 17, wherein said first and second facing layers are formed from a maferial selected from a group consisting of polyester, rayon, metallic foil and mixtures thereof.
A liner for an airstream conduit or housing, comprising:
- a nonlaminate pad of fibrous material having a lofty, acoustically insulating portion having a density of between substantially 8.0-80.0 kg/m3 and a relatively higher density skin along a first face thereof, said skin having a thickness of between substantially 0.25-10.0 mm and a density of between substantially 32.0-1600.0 kg/m3.
A liner, comprising:
- a nonlaminate pad of fibrous material having a lofty, acoustically insulating portion having a density of between substantially 8.0-80.0 kg/m3 and a relatively higher density skin along a first face thereof, said skin having a thickness of between substantially 0.25-10.0 mm and a density of between substantially 32.0-1600.0 kg/m3.
An acoustical liner with integral water barrier, comprising a pad of fibrous material having a lofty, acoustically insulating portion having a density of between substantially 8.0-80.0 kg/m3 and a relatively higher density, water-barrier skin along a first face thereof, said skin having a thickness of between substantially 0.25-7.5 mm and a density of between approximately 32.0-1600.0 kg/m3, further including a crimped margin, said crimped margin having a thickness of about 0.5-3.0 mm.
A door for a vehicle, comprising:
- an exterior body panel;
- an interior fascia panel connected to said exterior body panel and defining a cavity between said exterior body panel and said interior fascia panel;
- and
- a pad of fibrous material having a lofty, acoustically insulating portion having a density of between substantially 8.0-80.0 kg/m3 and a relatively higher density skin along a first face thereof, said skin having a thickness between substantially 0.25-7.5 mm and a density of between approximately 32.0-1600.0 kg/m3, further including a crimped margin having a thickness of about 0.5-3.0 mm.
A liner for an airstream conduit or housing, comprising:
- a pad of fibrous material having a lofty, acoustically insulating portion having a density of between substantially 8.0-80.0 kg/m3 and a relatively higher density skin along a first face thereof, said skin having a thickness of between substantially 0.25-10.0 mm and a density of between substantially 32.0-1600.0 kg/m3, wherein said fibrous material is selected from a group consisting of (a) thermoplastic polymer staple fibers and thermoplastic bicomponent fibers, (b) glass staple fibers and thermoplastic bicomponent fibers and (c) combinations of (a) and (b).
