Abstract

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