Abstract

The present invention relates to a method of manufacturing a fibre-reinforced spar cap (41) for a wind turbine. The method comprises the steps of providing a mould (62), and fastening a first guide member (64) and a second guide member (66) to the mould for providing a moulding cavity (68) in between the first and second guide members. A fibre material can be arranged within the moulding cavity, such that a first gap (72) is provided between the fibre material and the first guide member, and a second gap (74) is provided between the fibre material and second guide member. First and second inserts (78, 80) are inserted into the gap prior to resin infusion.
