The invention describes a method of moulding a wind turbine blade (1) in a mould (2), which method comprises the steps of applying a film (3) to an inside surface (20) of the mould (2); assembling component layers (10) for the wind turbine blade (1) on the film (3); performing curing steps to harden the component layers (10); and subsequently removing the cured wind turbine blade (1) from the mould (2). The invention further describes a film (3) suitable for use in a wind turbine blade moulding process, which film (3) comprises an outside surface (30) for lining a mould (2) and an inside surface (31) for receiving a wind turbine blade component layer (10) prior to curing, and wherein the inside and outside surfaces (30, 31) of the film (3) are realised to allow a complete detachment of the cured wind turbine blade (1) from the mould (2) after curing. The invention also describes a mould (2) for moulding a wind turbine blade (1) , comprising an inside surface (20) suitable for receiving such a film (3) and a vacuum extraction outlet (21) for applying a vacuum to extract air from between the film (3) and the mould inside surface (20). |
