Abstract: The present invention relates to a method of manufacturing a laminated composite item(l). The method may comprise the step of winding successive overlapping helical convolutions of resin impregnated tape (2) onto a mandrel (3) while advancing the tape back and forth along the mandrel. Sections of the tape being wound onto the mandrel near an end of the mandrel are folded to obtain an end surface of the composite item which is substantially-perpendicular to a longitudinal axis of the composite item. The present invention further relates to an alternative method of manufacturing a laminated composite item. This method comprises the steps of winding successive overlapping helical convolutions of resin impregnated first tape onto a mandrel while advancing the tape back and forth along the mandrel, and winding layers of a second tape having a straight edge (8a) and a serrated edge (8b) onto an end section of the mandrel to obtain an end surface of the composite item which is substantially perpendicular to a longitudinal axis of the composite item. The invention further relates to apparatuses for carrying out such methods and for wind turbine blade spars manufactured by such methods or by use of such apparatuses.

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.
