Abstract

A structural panel includes a first skin, a second skin and a core. The core is connected to the first skin and the second skin. The core includes a corrugated sheet of wire mesh that includes a plurality of corrugations. Each of the corrugations extends vertically between and engages the first skin and the second skin.

First claim

What is claimed is:

1. A structural panel, comprising:
a first skin having a first side surface, a second side surface, and a thickness extending there between, the first skin comprising a polymer or a sheet of metal;
a second skin having a first side surface, a second side surface, and a thickness extending there between; and
a core extending between the first side surface of the first skin and the first side surface of the second skin, which core includes a plurality of geometric structures formed of a wire mesh, which geometric structures extend between and are attached to the first skin and the second skin, wherein the wire mesh is configured from a plurality of wires woven together;
wherein the plurality of geometric structures include a plurality of corrugations, and the corrugations are linear and extend parallel to one another.

2. The structural panel of claim 1 , wherein each of the corrugations is formed by a first side portion, a second side portion, and an intermediate portion that extends between the first side portion and the second side portion.

3. The structural panel of claim 1 , wherein the panel has a length and the corrugations extend substantially an entirety of the length.

4. The structural panel of claim 1 , wherein the plurality of wires comprise a plurality of metal wires, a plurality of polymeric wires, a plurality of ceramic wires, or some combination thereof.

5. The structural panel of claim 1 , wherein the plurality of wires comprises a first wire of a first gauge and a second wire of a second gauge, which second gauge is different from the first gauge.

6. The structural panel of claim 1 , wherein the plurality of wires comprises a first wire of a first cross-sectional shape and a second wire of a second cross-sectional shape, which second cross-sectional shape is different from the first cross-sectional shape.

7. The structural panel of claim 1 , wherein the first skin and the second skin are substantially non-perforated.

8. The structural panel of claim 1 , wherein at least one of the first skin or second skin is perforated.

9. A structural panel, comprising:
a first skin having a first side surface, a second side surface, and a thickness extending there between, the first skin comprising a polymer or a sheet or layer of metal;
a second skin having a first side surface, a second side surface, and a thickness extending there between; and
a core extending between the first side surface of the first skin and the first side surface of the second skin, which core includes a plurality of geometric structures formed of a wire mesh, which geometric structures extend between and are attached to the first skin and the second skin, wherein the wire mesh is configured from a plurality of wires woven together;
wherein at least one of the first skin or second skin is perforated.

10. The structural panel of claim 9 , wherein the plurality of geometric structures include a plurality of corrugations.

11. The structural panel of claim 10 , wherein each of the corrugations is formed by a first side portion, a second side portion, and an intermediate portion that extends between the first side portion and the second side portion.

12. The structural panel of claim 10 , wherein the corrugations are linear and extend parallel to one another.

13. The structural panel of claim 10 , wherein the panel has a length and the corrugations extend substantially an entirety of the length.

14. The structural panel of claim 9 , wherein the plurality of wires comprises a plurality of metal wires, a plurality of polymeric wires, a plurality of ceramic wires, or some combination thereof.

15. The structural panel of claim 9 , wherein the plurality of wires comprises a first wire of a first gauge and a second wire of a second gauge, which second gauge is different from the first gauge.

16. The structural panel of claim 9 , wherein the plurality of wires comprises a first wire of a first cross-sectional shape and a second wire of a second cross-sectional shape, which second cross-sectional shape is different from the first cross-sectional shape.

17. The structural panel of claim 9 , wherein the plurality of geometric structures include a plurality of locally enclosed structures.

18. A component for an aircraft, comprising a nacelle comprising the structural panel of claim 1 .

19. A component for an aircraft, comprising a gas turbine engine comprising the structural panel of claim 1 .

20. A component for an aircraft, comprising:
an aircraft structure comprising the structural panel of claim 1 ;
the aircraft structure being an aircraft fuselage or an aircraft wing.
