Abstract

A composite structural component is disclosed. The composite structural component can include a lattice structure, a casing disposed about at least a portion of the lattice structure, and a skin adhered to a surface of the casing. The lattice structure and the casing can be formed of a polymeric material and the skin can be formed of a metallic material. A method of manufacturing a composite structural component is disclosed. The method can include creating a casing of a polymeric material and creating a lattice structure of a polymeric material disposed about at least a portion of the casing. The method can include sealing the porosity of the casing and lattice structure. The method can include adhering a skin of a metallic material to at least a portion of the casing. At least one of creating a lattice structure and creating a casing comprises utilizing an additive manufacturing process.

First claim

What is claimed is:

1. A method of manufacturing a composite structural component, comprising:
creating a casing of a polymeric material;
creating a lattice structure of a polymeric material disposed about at least a portion of the casing, wherein the casing defines at least one of an exterior or interior of the composite structural component; and
sealing the porosity of the casing and lattice structure sufficient to provide watertight integrity to the casing and the lattice structure.

2. The method of claim 1 , further comprising adhering a skin of a metallic material to at least a portion of the casing.

3. The method of claim 2 , wherein adhering a skin of a metallic material to a surface of the casing comprises plating the surface with the metallic material.

4. The method of claim 3 , wherein plating the surface with the metallic material comprises utilizing at least one of an electrolytic plating process and an electroless plating processes.

5. The method of claim 2 , further comprising adhering a portion of the skin to a portion of the lattice structure.

6. The method of claim 1 , wherein at least one of creating a lattice structure and creating a casing comprises utilizing an additive manufacturing process.

7. The method of claim 6 , wherein the additive manufacturing process comprises selective laser sintering (SLS), selective laser melting (SLM), fused deposition modeling (FDM), stereolithography (SLA), laminated object manufacturing (LOM), or combinations thereof.

8. The method of claim 1 , further comprising creating a second casing opposite the first casing, the first and second casings defining a void, wherein the lattice structure is disposed within the void about at least a portion of the second casing.

9. The method of claim 8 , wherein creating a second casing comprises utilizing an additive manufacturing process.

10. The method of claim 9 , further comprising adhering a portion of the skin to a surface of the second casing.

11. A method of manufacturing a composite structural component, comprising:
creating a first casing of a polymeric material;
creating a lattice structure of a polymeric material disposed about at least a portion of the first casing;
sealing the porosity of the casing and lattice structure sufficient to provide watertight integrity of the first casing and the lattice structure; and
utilizing an additive manufacturing process to create at least one of the lattice structure and the first casing.

12. The method of claim 11 , wherein the additive manufacturing process comprises selective laser sintering (SLS), selective laser melting (SLM), fused deposition modeling (FDM), stereolithography (SLA), laminated object manufacturing (LOM), or combinations thereof.

13. The method of claim 11 , further comprising adhering a skin of a metallic material to at least a portion of the first casing.

14. The method of claim 13 , wherein adhering a skin of a metallic material to a surface of the first casing comprises plating the surface with the metallic material.

15. The method of claim 11 , further comprising creating a second casing opposite the first casing, the first and second casings defining a void, wherein the lattice structure is disposed within the void about at least a portion of the second casing.

16. The method of claim 15 , wherein creating the second casing comprises utilizing an additive manufacturing process.

17. The method of claim 15 , further comprising adhering a portion of the skin to a surface of the second casing.

18. A method of manufacturing a composite structural component, comprising:
creating a first casing of a polymeric material;
creating a lattice structure of a polymeric material disposed about at least a portion of the first casing;
sealing the porosity of the first casing and lattice structure sufficient to provide watertight integrity to the first casing and the lattice structure; and
creating a second casing opposite the first casing, the first and second casings defining a void, wherein the lattice structure is disposed within the void about at least a portion of the second casing.

19. The method of claim 18 , wherein creating the first or second casings comprises utilizing an additive manufacturing process.

20. The method of claim 19 , wherein the additive manufacturing process comprises selective laser sintering (SLS), selective laser melting (SLM), fused deposition modeling (FDM), stereolithography (SLA), laminated object manufacturing (LOM), or combinations thereof.

21. The method of claim 18 , further comprising adhering a portion of a skin to a surface of the second casing.

22. The method of claim 18 , further comprising adhering a skin of a metallic material to at least a portion of the second casing.

23. The method of claim 22 , wherein adhering a skin of a metallic material to a surface of the second casing comprises plating the surface with the metallic material.
