Abstract: A method of manufacturing a wind turbine blade (10), comprising the steps of: - placing one or more shell fibre layers (95) on a mould surface of a blade mould (91), - placing a plurality of separately provided preforms (60) directly on the one or more shell fibre layers (95) in a stacked arrangement, - infusing and curing the stacked preform arrangement (51), the one or more shell fibre layers (95) together via a resin in mould cavity of the blade mould (91) to form a wind turbine blade (10) part with a spar cap (50) integrated in a shell part providing part of the aerodynamic shape of the wind turbine blade (10).

Abstract: A method of manufacturing a shell of a wind turbine blade (28) is disclosed. The method of manufacturing includes laying one or more layers of fiber on a surface of mould to form the shell. A spar element (60a) is positioned at a pre-defined position on the one or more layers of fiber, and a vacuum bag (100) is positioned or covered around the one or more layers of fiber and the spar element (60a). The method further includes step of infusion of resin through the one or more layers of fiber and the spar element. The resin is subsequently allowed to cure to obtain the shell (30a, 30b) of the wind turbine blade. The spar element is thus adhered to the shell through resin infusion process.
