Abstract

Method of manufacturing a fibre-reinforced spar cap (45) for a wind turbine blade. A plurality of pultruded fibre plates (70) is arranged in a spar cap mould (62) to form a stacked arrangement (69) of pultruded fibre plates (70). An insert member (86) is arranged next to a lateral surface (67) of the stacked arrangement (69), wherein the first insert member (86) comprises a connecting surface (87), and wherein the first insert member (86) is arranged such that its connecting surface abuts against the first lateral surface (67) of the stacked arrangement (69). Resin is infused into the stacked arrangement (69) and the insert member (86) to form the fibre-reinforced spar cap (45) or a preform thereof, which can be trimmed to the required size.
