Abstract

A shear web for a wind turbine blade is described. The shear web comprises a panel and a web head. A longitudinal edge of the panel is received within a slot defined in the web head. A plurality of discrete spring features are attached to the longitudinal edge of the panel. The spring features are mutually spaced apart at intervals along the length of the longitudinal edge. The spring features compress against a base of the slot when the longitudinal edge region of the panel is inserted into the slot.
