Abstract
A method for manufacturing a component for a wind turbine is provided. In a first step, a fiber material is laid onto a mold surface. In a further step, an uncured foam material is provided on top of the fiber material. Thereafter, the uncured foam material is cured to form a core member. Then, a resin impregnating the fiber material is cured to form the component. Thus, a core member for a component of a wind turbine can be provided easily.
Claims18
A method for manufacturing a blade for a wind turbine, comprising
- a) laying a fiber material onto one of a vacuum distribution layer and a surface of a mold,
- b) providing an uncured foam material to the mold and on top of the fiber material,
- c) curing the uncured foam material in the mold to form a core member,
- d) impregnating the fiber material with a resin;
- and
- e) curing the resin impregnating the fiber material to form the blade in the mold;
- wherein in or after step b) the mold has an arcuate curvature to shape the foam material in accordance with a desired geometry of the blade;
- wherein step b) is performed by an applicator comprising a geometry corresponding to the desired geometry of the blade, and wherein said applicator is moved across the mold and the foam material to shape the foam material.
