Abstract
A vehicle having a space filling panel including a polystyrene layer, a polyurethane layer, and a polyethylene cover where the polyethylene cover forms a vacuum sealed space. The polystyrene layer and the polyurethane layer are both positioned in the polyethylene cover's vacuum sealed space. In another embodiment, a space filling panel for a vehicle includes a polystyrene layer comprising a plurality of polyurethane chips. The polystyrene layer having the plurality of polyurethane chips is enclosed in a vacuum sealed space formed by a polyethylene cover.
Claims9
An acoustically absorptive space filling panel for a vehicle comprising:
- a polystyrene layer and a polyurethane layer with each layer having at least one surface with a non-planar surface geometry that couples the polyurethane layer to the polystyrene layer in a vacuum sealed space;
- and
- a polyethylene cover forming the vacuum sealed space;
- wherein the non-planar surface geometry does not extend entirely through either the polystyrene layer or the polyurethane layer.
A method for making a space filling panel in a vehicle comprising:
- forming a first layer having a first side with a non-planar surface geometry;
- forming a second layer having a second side with a complementary non-planar surface geometry;
- contacting the first side with the second side to couple the first and second layers;
- and
- vacuum sealing the first and second layers with a polymeric cover;
- wherein the space filling panel is disposed in the vehicle wherein the non-planar surface geometry and the complimentary non-planar surface geometry do not extend entirely through either the first layer or second layer.
