Abstract
A manufacturing method is described for a wind turbine blade, where layers of fiber material are laid up in a mold to form a portion of the blade structure. The fiber layers are infused with a resin which is subsequently cured to form the hardened blade structure. Some of the layers of fiber material are arranged so that a portion of the layers are kept resin-free during the infusion and curing steps, so that the fiber layer extends freely out from the external surface of the blade, preferably at the blade trailing edge, to provide a flexible blade trailing edge to reduce blade operational noise.
