Abstract

An under carpet heat shield/floor pan insulator (10) is provided for a vehicle. The shield/insulator includes an acoustical and thermal insulating layer of polymer fiber (12) that shows no signs of any thickness increase, delamination, deterioration or any undesirable effect which may affect performance for at least 330 hours when maintained at a temperature of at least approximately 150~C (302~F). The shield/insulator may include a relatively high density, nonlaminate skin of polymer fiber (14) and/or one or more facing layers constructed from polymer material (16, 20).

Claims (14)

WHAT IS CLAIMED IS:
1. An under carpet heat shield/floor pan insulator (10) for a vehicle, comprising:
a nonlaminate acoustical and thermal insulating layer of polymer fiber (12) selected from a group consisting of polyester, polypropylene, polyethylene, rayon, nylon and any mixtures thereof.
2. The shield/insulator of claim 1, wherein said acoustical and thermal insulating layer is a nonwoven fabric.
The shield/insulator of claim 1, wherein said acoustical and thermal insulating layer further includes additional fibers selected from a group consisting of glass fibers and natural fibers.
4. The shield/insulator of claim 1, including a relatively high density, nonlaminate skin of polymer fiber (14) along at least one face of said acoustical and thermal insulating layer.
5. The shield/insulator of claim 1, including a first metal foil facing layer (16) over a first face (18) of said acoustical and thermal insulating layer.
6. The shield/insulator of claim 5, including a second metal foil facing layer (20) over a second face (22) of said acoustical and thermal insulating layer.
7. The shield/insulator of claim 6, including an additional acoustical and thermal insulating layer of polymer fiber (24) selected from a group consisting of polyester, polypropylene, polyethylene, rayon, nylon and any mixtures thereof over said first metal foil facing layer wherein said first metal foil facing layer is sandwiched between said additional acoustical and thermal insulating layer and said acoustical and thermal insulating layer.
An under carpet heat shield/floor pan insulator (10) for a vehicle, comprising:
a nonlaminate acoustical and thermal insulating layer (12) of substantially 100% polyethylene terephthalate nonwoven fabric.
9. The shield/insulator of claim 8, including a relatively high density skin (14) along at least one face thereof.
10. The shield/insulator of claim 8, including a first metal foil facing layer (16) over a first face (18) of said acoustical and thermal insulating layer.
11. The shield/insulator of claim 10, including a second metal foil facing layer (20) over a second face (22) of said acoustical and thermal insulating layer.
12. The shield/insulator of claim 11, including an additional acoustical and thermal insulating layer of polymer fiber (24) selected from a group consisting of polyester, polypropylene, polyethylene, rayon, nylon and any mixtures thereof over said first metal foil layer wherein said first metal foil layer is sandwiched between said additional acoustical and thermal insulating layer and said acoustical and thermal insulating layer.
13. An under carpet heat shield/floor pan insulator (10) for a vehicle, comprising:
a nonlaminate acoustical and thermal insulating layer of polymer fiber (12) selected from a group consisting of polyester, polypropylene, polyethylene, rayon, nylon and any mixtures thereof that shows no signs of any thickness increase, delamination, deterioration or any undesirable effect which may affect performance for at least 330 hours at 150°C (302°F).
14. The shield/insulator of claim 13, wherein said acoustical and thermal insulating layer is a nonwoven fabric.
