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.
A fibre reinforcement fabric (802) for a wind turbine component, the fibre reinforcement fabric (802) comprising a first plurality of fibre bundles (512, 812) arranged in parallel in a warp direction and stitched together, the fibre reinforcement fabric (802) having a first outermost fibre bundle (581, 881, 1381) defining a first fabric edge (851, 1051, 1351) parallel to the warp direction and a second outermost fibre bundle (1382) defining a second fabric edge (852, 1052, 1352) opposite the first fabric edge, the fibre reinforcement fabric (802) having a first tapered portion including the first outermost fibre bundle (581, 881, 1381), wherein a thickness of the fibre reinforcement fabric (802) in the first tapered portion tapers from a first fabric thickness (835, 1035, 1335) to a second fabric thickness (836, 1036, 1336) in a direction towards the first fabric edge (851, 1051, 1351), and wherein the fibre reinforcement fabric (802) is pliable and drapeable.
