Abstract: In a first aspect of the invention there is provided a wind turbine blade comprising a shell and a shear web connected between a windward inner surface of the shell and a leeward inner surface of the shell. The shear web comprises an elongate web panel and a load-bearing flange extending transversely from a first side of the web panel to connect the shear web to the windward or leeward inner surface of the shell. The blade further comprises at least one non-structural flange extending transversely from a second side of the web panel. The non-structural flange has a substantially planar adhesive-receiving portion arranged in opposed relation to the windward or leeward inner surface of the shell. The load-bearing flange and the non-structural flange are formed of different materials.

Abstract: A method of making a wind turbine blade shear web. The method comprises providing a shear web mould. The shear web mould has a longitudinally-extending main surface shaped to form a main panel of the shear web, and first and second longitudinally extending side surfaces shaped to form respective first and second flange portions of the shear web. The method further comprises arranging one or more layers of fibrous material against the main surface and against the first and second side surfaces of the mould to form a layup that is generally C-shaped in cross-section. The method further comprises arranging a pre-cured return flange on the layup, providing uncured resin to the fibrous material of the layup and between the layup and the pre-cured return flange, and curing the uncured resin to co-bond the pre-cured return flange and the C-shaped layup.
