Abstract:
The invention relates to a method of preparing an assembly, comprising providing a first structure; providing a second structure; providing at least one flexible adhesive limiting member extending between said structures; and providing an adhesive between said structures to bind said structures to each other; wherein the adhesive is limited by the flexible adhesive limiting member such that a concave front line surface of the adhesive is defined. The invention also relates to such an assembly as well as to a wind turbine rotor blade, and to a wind turbine, comprising such an assembly.
Abstract:
A strip of fibre-reinforced polymeric material for a longitudinal reinforcing structure of a wind turbine blade, the strip having substantially flat upper and lower surfaces and extending longitudinally between first and second transverse edges, wherein an end region of the strip tapers in thickness towards the first transverse edge, and wherein one or more slots are defined in the tapered end region, the or each slot extending longitudinally from the first transverse edge of the strip into the tapered end region.
Abstract:
The invention relates to a method for manufacturing a composite material article, the method comprising -providing a mould (4), -placing at least one layer (1) of bulk fiber material on the mould (4), -placing, at an edge of the bulk fiber material layer (1), a flange element (2) partially overlapping the bulk fiber material layer (1), and partially extending so as to form a flange, and -curing bulk resin on the mould, where the bulk fiber material layer has been impregnated with the bulk resin,with the flange element (2) placed at the edge of the bulk fiber material layer (1).
