Abstract: The present invention relates to a method of manufacturing a wind turbine blade shell component (38), the method comprising the steps of providing a plurality of abraded pultrusion plates (64) having abraded edges, arranging the abraded pultrusion plates (64) in layers on blade shell material (89) in a mould (77) for the blade shell component, the layers being separated by electrically conductive interlayers, and bonding the abraded pultrusion plates (64) with the blade shell material to form the blade shell component, wherein each pultrusion plate (64) is formed of a pultrusion fibre material comprising glass fibres and carbon fibres. The invention also relates to a reinforcing structure for a wind turbine blade, the reinforcing structure comprising a plurality of pultrusion plates according to the present invention.

Abstract: The disclosure relates to a fibre reinforcement fabric for a wind turbine component, the fabric comprising a first plurality of fibre bundles arranged in parallel in a warp direction and stitched together, the fabric having a first outermost fibre bundle defining a first fabric edge parallel to the warp direction and a second outermost fibre bundle defining a second fabric edge opposite the first fabric edge, the fabric having a first tapered portion including the first outermost fibre bundle, wherein a thickness of the fabric in the first tapered portion is tapering from a first fabric thickness to a second fabric thickness in a direction towards the first fabric edge. The disclosure also relates to a spar cap and a wind turbine blade shell part comprising such fabric or fabrics.
