Abstract
Method of making a spar cap includes: providing a plurality of composite strips, each strip being of constant cross section defined by first and second sides and edges, the first and second sides comprising first and second abutment surfaces, the strip being of uniform thickness between the abutment surfaces, a first edge region of the strip comprising a first edge being of relatively reduced thickness, the first side of the strip comprising an edge surface, and the strip having a peel ply layer at least partially covering the first abutment surface and the edge surface; removing the peel ply layers; stacking the strips such that the first abutment surface abuts an abutment surface of an adjacent strip to define an interface region, such that a clearance region is defined; supplying resin to the respective clearance regions and causing the resin to infiltrate into the interface regions; and curing the resin.
