Abstract

An incombustible, non-telegraphing substrate for facing with a decorative aviation veneer is provided. The incombustible, non-telegraphing substrate comprises a backing layer comprising a polymer resin-impregnated paper and a fire-retardant chemical included in the backing layer and rendering the backing layer incombustible. An aviation panel and a method for installing the incombustible, non-telegraphing substrate in the aviation panel assembly are also provided.

First claim

The invention claimed is:

1. An incombustible, non-telegraphing substrate for facing with a decorative wood aviation veneer, the incombustible, non-telegraphing substrate comprising:
a backing layer comprising a polymer resin-impregnated paper;
a fire-retardant chemical included in the backing layer and rendering the backing layer incombustible; and
a wood sub-layer attached to the backing layer, the wood sub-layer comprising,
a first ply having a first grain orientation, and
a second ply underlying the first ply, the second ply having a second grain orientation different from the first grain orientation.

2. The incombustible, non-telegraphing substrate of claim 1 , wherein the decorative wood aviation veneer has a first surface and a second surface opposite to the first surface and the backing layer is configured to cover the first surface of the decorative wood aviation veneer.

3. The incombustible, non-telegraphing substrate of claim 2 , wherein a first adhesive attaches a first side of the backing layer to the first surface of the decorative wood aviation veneer.

4. The incombustible, non-telegraphing substrate of claim 3 , further comprising a wood sub-layer having a ply covering a second side of the backing layer, the wood sub-layer also including a fire-retardant chemical.

5. The incombustible, non-telegraphing substrate of claim 4 , wherein the wood sub-layer is adhered to the second side of the backing layer.

6. The incombustible, non-telegraphing substrate of claim 5 , wherein a second adhesive attaches the wood sub-layer to the second side of the backing layer.

7. An aviation panel assembly comprising:
a decorative aviation veneer comprising a species of wood;
an incombustible, non-telegraphing substrate faced with the decorative aviation veneer, the incombustible, non-telegraphing substrate comprising:
a backing layer comprising a polymer-resin impregnated paper, wherein a first side of the backing layer is attached to the decorative aviation veneer;
a wood sub-layer attached to a second side of the backing layer opposite the first side of the backing layer; and
a fire-retardant chemical included in the backing layer and the wood sub-layer; and

a first adhesive layer between the first side of the backing layer and the decorative aviation veneer.

8. The aviation panel assembly of claim 7 , wherein the decorative aviation veneer has a first surface and a second surface opposite the first surface, the backing layer has a first side and a second side, and the first adhesive layer is between the first side of the backing layer and the first surface of the decorative aviation veneer.

9. The aviation panel assembly of claim 8 , wherein the incombustible, non-telegraphing substrate backing layer directly covers the first surface of the decorative aviation veneer.

10. The aviation panel assembly of claim 8 , further comprising:
a wood sub-layer of one ply; and
a second adhesive layer between the wood sub-layer and the second side of the backing layer.

11. The aviation panel assembly of claim 9 , wherein the wood sub-layer covers the second side of the backing layer.

12. The aviation panel assembly of claim 7 , wherein the aviation panel assembly is configured for an aircraft interior and the first surface of the decorative aviation veneer is configured to be visible therein.

13. The aviation panel assembly of claim 10 , further comprising:
a honeycomb panel; and
a third adhesive layer between the honeycomb panel and at least one of the backing layer or the wood sub-layer.

14. A method for installing an incombustible, non-telegraphing substrate in an aviation panel assembly comprising:
adhering a backing layer of the incombustible, non-telegraphing substrate to a first surface of a decorative wood aviation veneer, the backing layer comprising a polymer resin-impregnated paper; and
adhering a wood sub-layer to a side of the backing layer opposite the decorative wood aviation veneer.

15. The method of claim 14 , wherein adhering the backing layer covers the first surface of the decorative aviation veneer.

16. The method of claim 15 , wherein adhering the incombustible, non-telegraphing substrate comprises adhering the first side of the backing layer directly to the first surface of the decorative aviation veneer.

17. The method of claim 16 , further comprising, prior to adhering the incombustible, non-telegraphing substrate to the first surface of the decorative aviation veneer:
adhering the wood sub-layer to the second side of the backing layer; and
fire treating the backing layer and wood sub-layer after adhering the wood sub-layer to the second side of the backing layer.

18. The method of claim 17 , further comprising fire treating the aviation panel assembly after adhering the incombustible, non-telegraphing substrate to the first surface of the decorative aviation veneer.

19. The method of claim 17 , further comprising attaching a structural member to an exposed ply of the wood sub-layer.

20. The method of claim 19 , wherein attaching the structural member to the exposed ply comprises adhering the structural member to the exposed ply of the wood sub-layer using a third adhesive.
