Abstract: A method of manufacturing a spar cap for a wind turbine blade part, comprise the steps of:



providing a plurality of precured elongated fibre reinforced resin elements
stacking the plurality of fibre reinforced elements, an interlayer of an elongated non-cured fibre material being arranged between successive fibre reinforced elements, thereby forming a stack of precured fibre reinforced elements,
moving the stack of fibre reinforced elements to a spar cap mould comprising a mould bottom and mould side walls,
arranging the stack of fibre reinforced elements in the cavity of the spar cap mould
infusing resin into the stack of fibre reinforced elements in the mould
allow the resin to cure and demould the stack

Abstract: A method for manufacturing a wind turbine blade, comprising the steps of:
providing one or more individual pultrusions including a first tapering end with a tapering end face terminating in a taper tip, and
arranging the one or more pultrusions in one layer or more stacked layers including at least a bottom layer on a first assembly surface at a first assembly station to provide a pultrusion arrangement extending in a longitudinal direction between a pultrusion root end and a pultrusion tip end, wherein the first tapering end of the one or more pultrusions form the pultrusion root end or the pultrusion tip end of the pultrusion arrangement.

Abstract: A main laminate forming a load carrying structure for a wind turbine blade, the main laminate extending in a spanwise direction from a proximal end through a transition region to a distal end, wherein the main laminate comprises: a top side, a bottom side, and a thickness direction extending between the top side and the bottom side; a pultrusion portion including a bottom pultrusion element extending to a transition end of a transition portion located in the transition region of the main laminate; a plurality of stacked fibre-reinforced elements including bottom and top fibre-reinforced elements extending to a transition end of a transition portion located in the transition region, wherein the pultrusion portion and the plurality of fibre-reinforced elements are connected by a joint in the transition region of the main laminate.
