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.
