Abstract: The invention relates to a method for curing of a composite material. The method involves applying heat to only a first region of said composite material, such that said first region is heated to a temperature above the cure onset temperature of said curable resin, thus initiating curing of said curable resin in said first region; and maintaining the composite material in an insulated state, such that the curing of said curable resin spreads to regions of the composite material outside of said first region.

Abstract: A method of making a wind turbine blade is described. The blade comprises an outer shell having a laminate structure. The method comprises providing a blade mould (82) defining a shape of at least part of the outer shell of the blade. The mould extends in a spanwise direction between a root end (94) and a tip end (96), and extends in a chordwise direction between a leading edge (90) and a trailing edge (92). The method further includes providing a plurality of dry plies (66) comprising dry structural fibrous material and a plurality of prepreg (68) plies comprising structural fibrous material impregnated with resin. The plurality of dry plies and the plurality of prepreg plies are arranged in the mould to form a plurality of layers of the laminate structure of the outer shell of the blade. The plies are arranged in the mould such that the dry plies are interleaved with the prepreg plies to form a hybrid shell structure in which the plies are arranged in a staggered relationship such that corresponding edges of the dry plies are offset from one another in the spanwise and/or chordwise direction of the mould and/or corresponding edges of the prepreg plies are offset from one another in the span-wise and/or chordwise direction of the mould.

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.
