Abstract: The present invention relates to a root end assembly (100) for incorporating a plurality of fastening members (74) into the root end of a wind turbine blade shell part during a moulding operation. The root end assembly (100) comprises a mounting plate (70) with a plurality of apertures (72) and a plurality of sheath members (83), each sheath member being disposed in a respective aperture of the plurality of apertures (72). Connection members (78) are received in the sheath members (83), and a plurality of said fastening members (74) are releasably attached to a respective connection member of the plurality of connection members (78) such that the fastening members (74) extend substantially normal to a first surface (77) of the mounting plate (70). The apertures (72) are dimensioned for allowing translational movement of the sheath members (83) in the respective apertures (72).

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.

Abstract: The present invention relates to a mould assembly (100) for manufacturing a wind turbine blade shell part, and to a method of manufacturing a wind turbine blade shell part using the mould assembly (100). The mould assembly (100) comprises a lowering device (85), which is adapted to carry and lower a root end insert onto the moulding surface of the mould, the lowering device (85) being attached to the mould and comprising a frame (86) for carrying the root end insert. Two synchronized hydraulic cylinders (91, 92) are used as driving means for lowering the frame, each hydraulic cylinder comprising a piston chamber and a rod chamber, wherein the piston chamber and the rod chamber of each cylinder are connected to each other via a respective valve assembly (110) comprising a fluid line (96) and a valve (97).

Abstract: The present invention relates to a method of manufacturing a wind turbine rotor blade part comprising stacking a plurality of plies (70, 71, 72) to form a stack of plies (80) such that the stack of plies has at least one stepwise tapering edge (84, 85). A plurality of plastic fasteners (90) is used to interconnect the plies (70, 71, 72) by passing the plurality of plastic fasteners (90) through the stack of plies to form a stack of interconnected plies (82). The stacks of interconnected plies (82a, 82b, 82c, 82d) are arranged within the blade mold, followed by resin infusion into the one or more stacks of interconnected plies within the blade mold, and curing and/or hardening the resin in order to form the blade part.

Abstract: A method of manufacturing a wind turbine blade part, such as a spar cap, by means of resin transfer moulding, preferably vacuum assisted resin transfer moulding, where fibre reinforcement material is impregnated with liquid resin in a mould cavity, wherein the mould cavity includes a rigid mould part having a mould surface defining a surface of the wind turbine blade part is described. The method includes the steps of: a) stacking a plurality of fibre reinforcement layers on the rigid mould part forming a fibre reinforcement stack, b) providing at least one flow-enhancing mat in the fibre reinforcement stack, c) sealing a second mould part, against the rigid mould part to form the mould cavity, d) optionally evacuating the mould cavity, e) supplying a resin to the mould cavity, and f) curing or hardening the resin in order to form the wind turbine blade part.
