Abstract
The present invention relates to a method of manufacturing a wind turbine blade. The method comprises adhesively joining a suction side shell half (69) and a pressure side shell half (68) along respective bond lines (80) at their leading and trailing edges, wherein, prior to joining, an impregnated carrier substrate (76) is arranged in between the shell halves along at least part of said bond lines (80). The carrier substrate (76) is impregnated with at least one compound having a functional moiety. The shell halves may be manufactured by placing a fibre lay-up including one or more fibre layers on a mould surface (66), arranging the impregnated carrier substrate (76) on the inside surface (72) at least along part of its peripheral edge (74) and injecting or infusing the fibre lay-up and the impregnated carrier substrate with a resin and subsequently curing the same.
