A WIND TURBINE BLADE AND AN ASSOCIATED MANUFACTURING METHOD |
摘要 |
A manufacturing method is described for a wind turbine blade (10), where layers of fibre material (72) are laid up in a mould to form a portion of the blade structure. The fibre layers are infused with a resin which is subsequently cured to form the hardened blade structure. Some of the layers of fibre material are arranged so that a portion (72a) of the layers are kept resin-free during the infusion and curing steps, so that the fibre layer extends freely out from the external surface of the blade, preferably at the blade trailing edge, to provide a flexible blade trailing edge (70b) to reduce blade operational noise. |
