Method of manufacturing a wind turbine blade with fewer manufacturing defects

A method of manufacturing a wind turbine blade, the blade 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, said method comprising:

• providing a mould (66);
• arranging one or more first layers of fibre material in the mould for providing an outer shell part (70);
• injecting the one or more first layers of fibre material with a curable resin;
• curing the resin to obtain an outer shell part (70);
• arranging a resin flow medium (76) on top of at least part of the outer shell part (70) followed by one or more second layers of fibre material for forming a load-carrying structure (74);
• injecting the resin flow medium (76) and the one or more second layers of fibre material for forming a load-carrying structure with a curable resin and curing the resin to adhere the outer shell part (70) to the load-carrying structure (74) to obtain a shell half of a wind turbine blade,
• wherein the resin flow medium (76) comprises a curing inhibitor.
