Method of manufacturing a wind turbine blade shell member with a fastening member and a wind turbine blade with a fastening member

摘要

A method of manufacturing a wind turbine blade shell member 2 with a fastening member 4 provided near a root end of the wind turbine blade shell member 2, the fastening member 4 being suitable for connecting a wind turbine blade comprising the wind turbine blade shell member 2 to a wind turbine hub, the method comprising the steps of providing a rigid outer mould 14 16, positioning the fastening member 4 near the end of the rigid outer mould 14 16 corresponding to the root end of the wind turbine blade, positioning at least two layers of pre-fabricated sticks 8 10near the end of the rigid outer mould 14 16 corresponding to the root end of the wind turbine blade such that prefabricated sticks 8 10surround a substantial longitudinal part of the fastening member 4 when the fastening member 4 is positioned in the wind turbine blade shell member 2, positioning one or more layers of pre-fabricated sticks 8 10in a substantial longitudinal part of the rigid outer mould 14 16, thereafter providing an inner mould in vacuum-tight connection with the rigid outer mould 14 16, evacuating the volume between the outer and the inner moulds, infusing a curable resin to secure the fastening member 4 to the enclosing pre-fabricated sticks 8 10and substantially fill empty space between adjacent sticks, and allowing the resin to cure, de-moulding the wind turbine blade shell member 2.
