Layer of material for uptake of excess adhesive
A method of joining at least two parts by adhesion is provided, the method including arrangement of a porous layer in the adhesive joint for taking up excess adhesive outside the adhesive joint as such. An element is also provided—including in particular a blade for a wind turbine—which is combined by adhesion of several parts, and wherein a porous layer is at least partially comprised in and at least partially protrudes from the adhesive joint between the parts and takes up excess adhesive outside the adhesive joint. The porous layer may be of a mesh-like structure or may have the structure of a sponge and may furthermore be entirely or partially pre-impregnated with adhesive.
1. A wind turbine blade comprising:
at least two parts of the wind turbine blade which are connected at a joint by at least one porous layer, which contacts the at least two parts, and which is impregnated with adhesive;
wherein the at least one porous layer is at least partially comprised in and at least partially protrudes from the joint connecting the at least two parts; and
wherein the porous layer is impregnated by the adhesive layer from absorption thereof while joining the at least two parts, whereby the porous layer takes up excess adhesive outside the joint.
2. The wind turbine blade of claim 1 , wherein the porous layer has a structure of a sponge with open pores.
3. The wind turbine blade of claim 1 , wherein the porous layer has mesh structure.
4. The wind turbine blade of claim 1 , wherein the porous layer comprises a felt of fibres.
5. The wind turbine blade of claim 1 , wherein the porous layer comprises a fibre material selected from the group consisting of glass fibres, plastics fibres and natural fibres.
