Abstract: A method of aligning shear webs for the construction of a wind turbine blade is provided. The method comprises providing one or more jigs (402), each configured to receive one or more spacer elements (701) and providing one or more spacer elements (701). First and second shear web panels are placed on the one or more jigs (402) to align them. The first and second shear web panels are restrained relative to each other and are separated by the one or more spacer elements. The first and second shear web panels are then removed together with the one or more spacer elements from the jig. A corresponding apparatus is also provided.

Abstract: A composite component (130) such as a shear web for a wind turbine blade is described. The component comprises a moulded laminate (44) formed from one or more fibrous layers (40) integrated by resin and defining a laminate edge (48). An edging strip (60) is located adjacent to the laminate edge (48) and is integrated with the laminate. In a particular example, the edging (60) is made from closed-cell foam. Accordingly, resin does not permeate into the bulk of the edging (60) during the moulding process. After the moulding process, a portion (60a) of the edging (60) is removed to reveal an exposed, substantially resin-free surface of the edging which defines a safety edge (64) of the component.
