Abstract
A vehicle headliner including a shell having a first layer made of a polymeric resin sheet with glass fibers interspersed within the resin sheet, and a second layer of fibrous material having sound attenuating properties. In a preferred method of manufacturing the shell of a headliner the first and second layers are heated such that the temperature of the first layer is different than the temperature of the second layer. The first and second layers are then inserted into a mold having a desired contoured shape. The first and second layers are then compressed together to bond the layers, thereby forming the shell.
Claims20
A vehicle headliner comprising:
- a first layer made of a polymeric resin sheet with glass fibers interspersed within said resin sheet;
- and
- a second layer of fibrous material having sound attenuating properties.
A vehicle headliner comprising:
- an upper layer made of a polymeric resin sheet with glass fiber interspersed within said resin sheet;
- an intermediate layer of fibrous material made of polyethylene terephthalate;
- and
- a cover layer at least partially including a layer of foam, wherein said intermediate layer is disposed between said upper layer and said cover layer.
A method of forming a shell for a vehicle headliner comprising the steps of:
- a. providing a first layer made of polymeric resin sheet with glass fibers interspersed within said resin sheet;
- b. providing a second layer of fibrous material having sound attenuating properties;
- c. heating the first layer and second layers such that the temperature of the first layer is different than the temperature of the second layer;
- d. inserting the first and second layers into a mold having a desired contoured shape;
- and
- e. compressing the first and second layers together to bond the layers, thereby forming the shell.
