Abstract: A method for manufacturing a wind turbine blade shell part (11) made of a fibre-reinforced composite structure, including steps of mounting a plurality of fastening devices (74) on a mounting plate (70) to form a root end assembly, the mounting plate comprising one or more first openings (101) for evacuating air; arranging the root end assembly over a mould surface (22) of a mould (20); arranging an air-tight cover member (80) 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.
