Abstract: The present invention relates to a method and to a mould system (70) for manufacturing a shear web for a wind turbine blade as well as to a backing plate (66) for such method and mould system. The method involves arranging one or more fibre layers on top of a web mould part (61), arranging backing plates (66) at each end to create a mould cavity between the first and second backing plate (66, 68) and the web mould part (61). Each backing plate (66, 68) comprises an inner moulding surface (80), outer surfaces (98, 100) and a channel (82) or groove (83) extending between at least one of the outer surfaces (98, 100) and the inner moulding surface (80). Resin is supplied to the mould cavity via each channel or groove of the first and second backing plate (66, 68), and subsequently the resin is cured or hardened to form the shear web.

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.
