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.
