Abstract
The present invention provides a method of repairing a metal mesh in a wind turbine blade part, damaged for instance by a lightning strike. The method comprises providing a wind turbine blade part; exposing a first metal mesh comprised in the wind turbine blade part; adhesively attaching a second metal mesh to the first metal mesh using an electrically conductive adhesive, such that the second metal mesh at least partially overlaps the first metal mesh; and covering the second metal mesh with cover material to finalise the repair. A corresponding wind turbine blade part is also provided.
Claims14
A method for repairing a wind turbine blade part, the method comprising:
- exposing a first metal mesh comprised in the wind turbine blade part;
- adhesively attaching a second metal mesh to the first metal mesh using an electrically conductive adhesive, such that the second metal mesh at least partially overlaps the first metal mesh;
- covering the second metal mesh with a cover material to repair the wind turbine blade part, the cover material comprising at least one of a fiber-reinforcement material or a coating;
- wherein the exposed first metal mesh comprises a defect, the method further comprising covering at least the defect with the second metal mesh to patch the defect;
- and
- wherein at least one of a thickness of at least part of the exposed first metal mesh or a thickness of the second metal mesh is reduced by 20-80%.
