Abstract
A method for preparing a wind turbine blade shell member including a plurality of elements of cured fiber-reinforced sheet material is provided. A plurality of elements of cured fiber-reinforced sheet material is provided in a mould, a resin is introduced between the elements of cured fiber-reinforced sheet material and the elements are bonded to adjacent elements by curing the resin. The method is particularly suitable for preparing wind turbine blade shell members due to the complex three-dimensional shape of the airfoils, which may be resembled by the relatively flexible cured fiber-reinforced sheet material.
Claims49
A method of manufacturing a wind turbine blade shell member comprising the steps of:
- providing a mould;
- positioning a plurality of elements of cured fibre-reinforced sheet material in the mould, wherein at least some of the elements of cured fibre-reinforced sheet material are positioned as partially overlapping tiles so that a number of substantially parallel element edges are provided;
- optionally providing at least one of an outer surface layer material and an inner surface layer material in the mould;
- introducing a curable resin between substantially all of the elements of cured fibre-reinforced sheet material;
- and
- bonding the plurality of elements of cured fibre-reinforced sheet material by curing the resin.
