Abstract

Decorative laminates having an open-cell foam layer are disclosed herein. An example decorative laminate includes a decorative layer, an open-cell foam layer coupled to the decorative layer and an adhesive layer coupled to the open-cell foam layer.

First claim

What is claimed is:

1. An apparatus comprising:
a panel to be disposed in a cabin of an aircraft, the panel constructed of material that outgasses over time; and
a decorative laminate coupled to the panel, the decorative laminate including:
a decorative layer;
an open-cell foam layer having a first side and a second side opposite the first side, the decorative layer coupled to the first side of the open-cell foam layer, the open-cell foam layer constructed of open-cell metal foam or open-cell ceramic foam with cells having a size up to approximately 6.35 millimeters (mm); and
a pressure sensitive adhesive layer coupled to the second side of the open-cell foam layer such that the open-cell foam layer is disposed between the decorative layer and the pressure sensitive adhesive layer, the pressure sensitive adhesive coupled to the panel, the pressure sensitive adhesive layer including venting pathways extending randomly through a thickness of the pressure sensitive adhesive layer, such that air disposed between the decorative laminate and the panel when the decorative laminate is coupled to the panel and gas vented from the panel after the decorative laminate is coupled to the panel is vented through the pressure sensitive adhesive layer and the open-cell foam layer to an edge of the open-cell foam layer to atmosphere to prevent bubbles from forming between the decorative laminate and the panel over time.

2. The apparatus of claim 1 , wherein the cells have a size of approximately 1 nanometer to approximately 1 millimeter.

3. The apparatus of claim 1 , wherein an open-cell content of the open-cell foam layer is approximately 10% to approximately 100%.

4. The apparatus of claim 1 , wherein a void fraction of the open-cell foam layer is approximately 10% to approximately 98%.

5. An aircraft comprising:
a cabin; and
the apparatus of claim 1 disposed in the cabin.

6. The apparatus of claim 1 , wherein the pressure sensitive adhesive layer includes fibers, the venting pathways formed in the pressure sensitive adhesive layer adjacent the fibers.

7. The apparatus of claim 1 , wherein the pressure sensitive adhesive layer includes particulate, the venting pathways formed in the pressure sensitive adhesive layer adjacent the particulate.

8. The apparatus of claim 1 , wherein the decorative layer defines an outermost layer of the decorative laminate, the decorative layer including an embossing resin layer, a top sheet layer, and an ink composition layer between the embossing resin layer and the top sheet layer, the embossing resin layer of the decorative layer coupled to the first side of the open-cell foam layer, the top sheet layer being at least partially transparent, such that the ink composition layer is visible through the top sheet layer to provide a decorative effect to the panel.

9. The apparatus of claim 8 , wherein the embossing resin layer is constructed of a low heat release resin, a thermosetting resin, or a thermoplastic resin.

10. The apparatus of claim 8 , wherein the top sheet layer is constructed of a transparent thermoplastic polymer.

11. A method of manufacturing an apparatus, the method comprising:
producing a decorative laminate including:
coupling a decorative layer to a first side of an open-cell foam layer, the open-cell foam layer constructed of open-cell metal foam or open-cell ceramic foam with cells having a size up to approximately 6.35 millimeters (mm); and
coupling a pressure sensitive adhesive layer to a second side of the open-cell foam layer opposite the first side of the open-cell foam layer such that the open-cell foam layer is disposed between the decorative layer and the pressure sensitive adhesive layer, the pressure sensitive adhesive layer including venting pathways extending randomly through a thickness of the pressure sensitive adhesive layer; and

applying the decorative laminate to a panel to be disposed in a cabin of an aircraft by contacting the pressure sensitive adhesive layer with the panel, the panel constructed of material that outgasses over time, wherein air disposed between the decorative laminate and the panel when the decorative laminate is coupled to the panel and gas vented from the panel after the decorative laminate is coupled to the panel is vented through the pressure sensitive adhesive layer and the open-cell foam layer to an edge of the open-cell foam layer to atmosphere to prevent bubbles from forming between the decorative laminate and the panel over time.

12. The method of claim 11 , wherein the cells have a size of approximately 1 nanometer to approximately 1 millimeter.

13. The method of claim 11 , wherein an open-cell content of the open-cell foam layer is approximately 10% to approximately 100%.

14. The method of claim 11 , wherein a void fraction of the open-cell foam layer is approximately 10% to approximately 98%.

15. The method of claim 11 , wherein the decorative layer defines an outermost layer of the decorative laminate, the decorative layer including an embossing resin layer, a top sheet layer, and an ink composition layer between the embossing resin layer and the top sheet layer, the embossing resin layer of the decorative layer coupled to the first side of the open-cell foam layer, the top sheet layer being at least partially transparent, such that the ink composition layer is visible through the top sheet layer to provide a decorative effect to the panel.

16. The method of claim 15 , wherein the embossing resin layer is constructed of a low heat release resin, a thermosetting resin, or a thermoplastic resin.

17. The method of claim 11 , wherein the pressure sensitive adhesive layer includes fibers, the venting pathways formed in the pressure sensitive adhesive layer adjacent the fibers.

18. The method of claim 11 , wherein the pressure sensitive adhesive layer includes particulate, the venting pathways formed in the pressure sensitive adhesive layer adjacent the particulate.

19. The method of claim 11 , further including, prior to applying the decorative laminate to the panel, removing a liner from the adhesive layer.

20. The method of claim 19 , wherein the liner is constructed of at least one of paper, plastic film, or poly coated paper.
