Abstract

A method of making an elongate reinforcing structure, such as a shear web, for a wind turbine blade is described. The reinforcing structure comprises a longitudinally-extending web and a longitudinally-extending flange. The flange extends along a longitudinal edge of the web and is arranged transversely to the web. The method involves providing a flange structure comprising a flange portion, and a projecting portion that extends along the length of the flange portion and projects transversely from a surface of the flange portion. The projecting portion is bonded between laminate layers of the web. The flange structure is preferably a pultruded component having a T-shaped cross-section. The method allows a simple, inexpensive and reconfigurable mould tool to be used. In preferred embodiments the mould tool has a flat surface without sidewalls.
