Abstract

The disclosure presents a wind turbine blade and a method of manufacturing a wind turbine blade, wherein the wind turbine blade is manufactured as a composite structure comprising a reinforcement material embedded in a polymer matrix, the method comprising: providing a first blade mould with a first blade shell part having a leading edge, a trailing edge, and a first leading edge glue surface at the leading edge, the first blade mould comprising a first leading edge flange; providing a second blade mould with a second blade shell part having a leading edge, a trailing edge, and a second leading edge glue surface at the leading edge, the second blade mould comprising a second leading edge flange; applying glue to a leading edge glue surface; providing one or more leading edge spacer elements at a leading edge flange; arranging the second blade mould on the first blade mould, such that the one or more leading edge spacer elements are arranged between the first leading edge flange and the second leading edge flange; applying a pressure to the second blade shell part; and curing the glue.
