Abstract

A structural arrangement comprising a fiber reinforced polymer component, a cold gas spraying electrically conductive layer, and a polyether sulfone foil arranged on the fiber reinforced polymer component, at least in a region between the fiber reinforced polymer component and the cold gas sprayed electrically conductive layer.

First claim

What is claimed is:

1. A structural arrangement, comprising:
a fiber reinforced polymer component having an outer surface with a first region and a second region;
a cold gas sprayed electrically conductive layer; and
a polyether sulfone foil that is arranged on the first region of the fiber reinforced polymer component between the fiber reinforced polymer component and the cold gas sprayed electrically conductive layer; and
wherein neither the cold gas sprayed electrically conductive layer nor any polyether sulfone foil is arranged on the second region of the fiber reinforced polymer component.

2. The structural arrangement of claim 1 ,
wherein the polyether sulfone foil is bonded onto the first region of the fiber reinforced polymer component.

3. The structural arrangement of claim 2 ,
wherein the polyether sulfone foil is merged with epoxy resin of the fiber reinforced polymer component.

4. The structural arrangement of claim 1 ,
wherein the polyether sulfone foil exhibits a thickness in a range of 50 μm to 100 μm.

5. The structural arrangement of claim 1 ,
wherein the cold gas sprayed electrically conductive layer comprises copper, aluminium, silver, tin and/or alloy particles.

6. The structural arrangement of claim 1 ,
wherein the polyether sulfone foil comprises at least one strip and/or patch made of polyether sulfone.

7. A rotary wing aircraft with a structural arrangement according to claim 1 .

8. A structural arrangement, comprising:
a fiber reinforced polymer component having an outer surface with a first region and a second region;
a polyether sulfone foil on the first region of the fiber reinforced polymer component; and
an electrically conductive layer on the polyether sulfone foil, the electrically conductive layer formed by cold gas spraying electrically conductive particles onto the polyether sulfone foil to create the electrically conductive layer; and
wherein the polyether sulfone foil is arranged between the fiber reinforced polymer component and any cold gas sprayed electrically conductive layer and neither the polyether sulfone foil nor the electrically conductive layer is on the second region of the fiber reinforced polymer component.

9. The structural arrangement of claim 8 ,
wherein the polyether sulfone foil is bonded onto the first region of the fiber reinforced polymer component.

10. The structural arrangement of claim 8 ,
wherein the polyether sulfone foil is merged with epoxy resin of the fiber reinforced polymer component.

11. The structural arrangement of claim 8 ,
wherein the polyether sulfone foil exhibits a thickness in a range of 50 μm to 100 μm.

12. The structural arrangement of claim 8 ,
wherein the electrically conductive layer comprises copper, aluminum, silver, tin and/or alloy particles.

13. A structural arrangement comprising:
a fiber reinforced polymer panel having an outer surface with a first region and a second region;
an electrically conductive layer; and
a polyether sulfone foil disposed on and integrally formed with the first region of the fiber reinforced polymer panel between the fiber reinforced polymer panel and the electrically conductive layer; and
wherein the electrically conductive layer comprises two strips extending in different directions and electrically connected to each other by a junction; and
neither the electrically conductive layer nor any polyether sulfone foil is disposed on the second region of the fiber reinforced polymer panel.

14. The structural arrangement of claim 13 ,
wherein the polyether sulfone foil is bonded to the first region of the fiber reinforced polymer panel.

15. The structural arrangement of claim 13 ,
wherein the polyether sulfone foil is merged with epoxy resin of the fiber reinforced polymer panel.

16. The structural arrangement of claim 13 ,
wherein the polyether sulfone foil has a thickness of 50 μm to 100 μm.

17. The structural arrangement of claim 13 ,
wherein the electrically conductive layer is a cold gas sprayed electrically conductive layer and the cold gas sprayed electrically conductive layer comprises copper, aluminium, silver, tin and/or alloy particles.

18. The structural arrangement of claim 13 ,
wherein the electrically conductive layer is a cold gas sprayed electrically conductive layer and the cold gas sprayed electrically conductive layer comprises copper particles.

19. The structural arrangement of claim 13 ,
wherein the polyether sulfone foil comprises at least one strip and/or patch made of polyether sulfone.

20. A rotary wing aircraft with a structural arrangement according to claim 13 .
