1. A wind turbine blade (10) having a profiled contour including a pressure side and a suction side, and a leading edge and a trailing edge with a chord having a chord length extending therebetween, the wind turbine blade extending in a spanwise direction between a root end and a tip end, wherein the wind turbine blade comprises an elongate reinforcing structure (62), the reinforcing structure (62) comprising:
a plurality of strips (63, 64, 65) of fibre-reinforced polymer arranged into adjacent stacks (66) of strips; and
at least one alignment member (68) comprising a plurality of horizontal segments (70) and a plurality of vertical segments (72), wherein the plurality of horizontal segments (70) and the plurality of vertical segments (72) are arranged in an alternating arrangement with respect to one another, wherein one of the vertical segments (72) of the at least one alignment member is arranged between adjacent stacks of strips, and wherein one of the horizontal segments (70) of the at least one alignment member is arranged on top of or below each of the stacks of strips,
wherein at least one of the vertical segments (72) comprises one or more apertures (84) for allowing resin to flow from one side of the at least one of the vertical segments to the other side of the at least one of the vertical segments.
