Assembly and method of preparing an assembly
The invention relates to a method of preparing an assembly, including providing a first structure; providing a second structure; providing at least one flexible adhesive limiting member extending between the structures; and providing an adhesive between the structures to bind the structures to each other; wherein the adhesive is limited by the flexible adhesive limiting member such that a concave front line surface of the adhesive is defined. The invention also relates to such an assembly as well as to a wind turbine rotor blade, and to a wind turbine, having such an assembly.
1. A method of preparing an assembly, comprising:
providing a first structure;
providing a second structure;
providing at least one flexible adhesive limiting member extending between the structures; and
providing an adhesive between the structures to bind the structures to each other; wherein the adhesive is limited by the flexible adhesive limiting member such that a concave front line surface of the adhesive is defined.
2. The method according to a claim 1 , wherein the first and second structure and the at least one flexible adhesive limiting member are arranged to form at least one channel for guiding and shaping the adhesive.
3. The method according to claim 1 , wherein the flexible adhesive limiting member is removed after curing of the adhesive.
4. The method according to claim 1 , wherein the flexible adhesive limiting member is attached to the first structure and abut, during elastic deformation, the second structure.
5. The method according to claim 1 , wherein the flexible adhesive limiting member is a flexible tubing.
6. The method according to claim 1 , wherein the flexible adhesive limiting member has been produced from a closed cell foam, such as from closed cell polyethylene or from foamed nitrile rubber.
7. The method according to claim 1 , wherein the structures are bound to each other by the adhesive to form a lap joint.
8. The method according to claim 1 , wherein the structures are bound to each other by the adhesive to form a butt joint.
9. The method according to claim 1 , wherein the first and second structures are shell members of a wind turbine rotor blade, the shell members being bound to each other by the adhesive at the leading edge or at the trailing edge of the wind turbine rotor blade.
10. The method according to claim 1 , wherein one of the first and the second structure is a shell member of a wind turbine rotor blade, and the other one of the first and the second structure is a spar, or a spar cap, of a wind turbine rotor blade.
11. An assembly comprising a first and a second structure, said structures being bound to each other by means of an adhesive, said adhesive having a concave front line surface; and, a flexible adhesive limiting member extending between said structures and defining said concave front line surface of the adhesive.
12. A wind turbine rotor blade comprising an assembly according to claim 11 .
13. A wind turbine comprising an assembly according to claim 11 .
