Abstract
A wind turbine blade having a spar cap disposed between layers constituting an outer skin or disposed on an inner side of the outer skin and a method of manufacturing the wind turbine blade are provided, wherein in manufacture of the wind turbine blade, generation of manufacturing defects, such as misalignment and wrinkles in fabrics, can be suppressed and the time required for repairing the defects as well as for laminating the layers can be reduced. In the method of manufacturing the wind turbine blade having the spar cap as a main structural member of the blade disposed between the layers constituting the outer skin or disposed on the inner side of the outer skin, the spar cap is formed as a separate piece from the outer skin, and the spar cap, dry fiber fabrics for the layers constituting the outer skin, and a sandwich core member are collectively impregnated with resin under a vacuum process.
