Abstract

In order to provide a new and improved bonding arrangement, especially for use in an aircraft or spacecraft, which is designed to overcome problems of bonding arrangements under Mode I loading stress and which is designed or configured particularly to create a bond design which is incapable of locally loading the adhesive bond above the peel strength, a bonding arrangement is disclosed with a coating structure, which is split into a plurality of neighboring structural elements spatially separated from each other, and at least one supporting member is provided, which comprises a plurality of recesses receiving the structural elements in operating position.

First claim

The invention claimed is:

1. A bonding arrangement for the assembly of structures, the structures comprising at least one substrate member to which at least one coating structure is applied, the substrate member and the coating structure comprising a common interface which forms at least one bond, the at least one bond being configured as an adhesive bond, wherein the coating structure is split into a plurality of neighboring structural elements spatially separated from each other, and wherein at least one supporting member is provided, which comprises a plurality of recesses receiving the structural elements in operating position,
wherein an intermediate layer is arranged between the supporting member and the neighboring structural elements of the coating structure,
wherein the intermediate layer provides the mechanical properties of a spring between the supporting member and the respective neighboring structural element, and
wherein the intermediate layer having the mechanical properties of a spring shows an asymptotic load vs. displacement loading behavior.

2. The bonding arrangement of claim 1 , wherein the at least one supporting member covers the surfaces of the neighboring structural elements facing the recesses.

3. The bonding arrangement of claim 1 , wherein the at least one supporting member forms a bracket surrounding each of the neighboring structural elements of the coating structure at least in part.

4. The bonding arrangement of claim 1 , wherein the supporting member and the neighboring structural elements of the coating structure are connected indirectly.

5. The bonding arrangement of claim 1 , wherein the intermediate layer comprises an anisotropic lattice material.

6. The bonding arrangement of claim 5 , wherein the lattice material is formed by at least one of a foam, a super-elastic polymer and a multi-material combination, each showing asymptotic spring loading behavior.

7. The bonding arrangement of claim 5 , wherein the anisotropic lattice material is formed by at least one of at least one elastomeric foam, by a super-elastic alloy and a shape memory alloy.

8. The bonding arrangement of claim 7 , wherein the shape memory alloy comprises at least one of a copper-aluminium-nickel alloy, a Nitinol shape memory alloy and a super-elastic polyisoprene-based polymer.

9. The bonding arrangement of claim 1 , wherein the plurality of neighboring structural elements comprises a regular structure.

10. A bonding arrangement for the assembly of structures, the structures comprising at least one substrate member to which at least one coating structure is applied, the substrate member and the coating structure comprising a common interface which forms at least one bond, the at least one bond being configured as an adhesive bond, wherein the coating structure is split into a plurality of neighboring structural elements spatially separated from each other, and wherein at least one supporting member is provided, which comprises a plurality of recesses receiving the structural elements in operating position,
wherein an intermediate layer is arranged between the supporting member and the neighboring structural elements of the coating structure, and
wherein between contacting surfaces of at least two of the structural elements, the intermediate layer, and the supporting member an adhesive means is arranged.

11. The bonding arrangement of claim 10 , wherein the intermediate layer provides the mechanical properties of a spring between the supporting member and the respective neighboring structural element.

12. The bonding arrangement of claim 11 , wherein the intermediate layer having the mechanical properties of a spring shows an asymptotic load vs. displacement loading behavior.

13. A vehicle provided with at least one device comprising an assembled structure with a bonding arrangement, the structure comprising at least one substrate member to which at least one coating structure is applied, the substrate member and the coating structure comprising a common interface which forms at least one bond, the at least one bond being configured as an adhesive bond, wherein the coating structure is split into a plurality of neighboring structural elements spatially separated from each other, and wherein at least one supporting member is provided, which comprises a plurality of recesses receiving the structural elements in operating position.

14. A bonding arrangement for the assembly of structures, the structures comprising at least one substrate member to which at least one coating structure is applied, the substrate member and the coating structure comprising a common interface which forms at least one bond, the at least one bond being configured as an adhesive bond, wherein the coating structure is split into a plurality of neighboring structural elements spatially separated from each other, and wherein at least one supporting member is provided, which comprises a plurality of recesses receiving the structural elements in operating position,
wherein an intermediate layer is arranged between the supporting member and the neighboring structural elements of the coating structure, and
wherein the intermediate layer comprises an anisotropic lattice material.

15. The bonding arrangement of claim 14 , wherein the lattice material is formed by at least one of a foam, a super-elastic polymer and a multi-material combination, each showing asymptotic spring loading behavior.

16. The bonding arrangement of claim 14 , wherein the anisotropic lattice material is formed by at least one of at least one elastomeric foam, by a super-elastic alloy and a shape memory alloy.

17. The bonding arrangement of claim 16 , wherein the shape memory alloy comprises at least one of a copper-aluminium-nickel alloy, a Nitinol shape memory alloy and a super-elastic polyisoprene-based polymer.

18. The bonding arrangement of claim 14 , wherein the at least one supporting member covers the surfaces of the neighboring structural elements facing the recesses.

19. The bonding arrangement of claim 14 , wherein the at least one supporting member forms a bracket surrounding each of the neighboring structural elements of the coating structure at least in part.
