Abstract
A method of manufacturing a wind turbine blade using pre-fabricated stacks of reinforcing material is described. The stacks 14 comprise a plurality of plies of fiber material, joined together along a side edge to form a spine. The opposite edges of the stack are left unjoined so that the plies can separate and slide across one another. In doing so, the stacks can be stored flat, but on installation into a curved mold 12 profile, the plies may slide to adopt the curved shape of the mold. The stacks extend from a point near the leading or trailing edge of the mold to an intermediate point on the mold surface. The stacks may be used to construct the thickened root section of a wind turbine blade.
