Abstract: The present invention relates to a method for manufacturing a wind turbine blade shell part made of a fibre-reinforced composite structure, including steps of mounting a plurality of fastening devices on a mounting plate to form a root end assembly, the mounting plate comprising one or more first openings for evacuating air; arranging the root end assembly over a mould surface of a mould; arranging an air-tight cover member so as to form a mould cavity; evacuating air from the mould cavity via at least the one or more first openings of the mounting plate; and supplying a polymer into the mould cavity and allowing the polymer to cure so as to form the composite structure. A root end assembly for use in the method is also provided.
