Abstract

A composite component (130) such as a shear web for a wind turbine blade is described. The component comprises a molded 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 molding process. After the molding 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.
