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
