Abstract
A method for preparing a wind turbine blade shell member comprising 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 mold, 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.
Claims13
A wind turbine blade comprising cured fibre-reinforced sheet material positioned near an outer surface of the blade and positioned as at least partially overlapping tiles so that a number of substantially parallel element edges are provided, the substantially parallel element edges extending along a majority of the longitudinal length of the wind turbine blade, wherein the fibre-reinforced sheet material is pultruded or band pressed fibre-reinforced sheet material.
A wind turbine blade comprising cured fibre-reinforced sheet material positioned near an outer surface of the blade and configured as partially overlapping tiles, wherein the fibre-reinforced sheet material is pultruded or band pressed fibre-reinforced sheet material,
- wherein elements of the fibre-reinforced sheet material form an overall reinforcement structure, the structure having at least two legs towards a first end of the wind turbine blade shell member, at least two legs towards a second end of the wind turbine blade shell member, or both.
