1. A wind turbine blade, comprising:
a shell,
a shear web connected between a windward inner surface of the shell and a leeward inner surface of the shell, the shear web comprising:
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, and
at least one non-structural flange extending transversely from a second side of the web panel, the non-structural flange having a planar adhesive-receiving portion arranged in opposed relation to the windward or leeward inner surface of the shell,
wherein the load-bearing flange and the non-structural flange are formed of different materials, and
wherein the non-structural flange is formed of a plurality of longitudinal flange sections arranged end to end along the length of the shear web.
