Abstract: The invention relates to a method for reinforcing a part of the outer surface of a wind turbine blade, said method comprises the steps: i) providing a blade plug having an outer surface resembling the topography of the outer surface of at least a leading portion of at least part of the length of a wind turbine blade; ii) casting a mold of part of the blade plug obtained in step i) in such a way that the topography of an inner surface of said mold corresponds to the topography of part of an outer surface of said blade plug provided in step i); iii) from the mold obtained in step ii), preparing a protective shell by making a casting of the inner surface of said mold; said protective shell is comprising an inner surface and an outer surface, said protective shell is being made from one or more predetermined materials; iv) starting from the topography of the surface of the wind turbine blade; or starting from a blade plug as obtained in step i) preparing an enlarged plug; said enlarged plug thereby comprising an

Abstract: This invention relates to a wind turbine blade with retrofitted coating in and around areas where the blade is especially exposed to erosion damages, which is established by the coating including a glue layer, a fiber reinforced polymer layer and one or more non-reinforced polymer layers over the fiber reinforced layer, since the polymer layers stretch themselves out over the fiber reinforced layer and includes areas of the wind turbine blade's surface, which are less exposed to erosion damages. A method for creation of such a wind turbine blade and creation of such a coating and the coating itself, is also established with the invention.

Abstract: A method for manufacturing a component for a wind turbine is provided. An embodiment of the method includes: a) covering a mold surface with a peel-off layer, b) providing a layup of fiber material on top of the peel-off layer, c) curing a resin impregnating the fiber material to form the component, and d) peeling the peel-off layer off the component. The method is advantageous in that it avoids sanding or sandblasting of a cured blade to remove a release agent adhering to the blade surface.

Abstract: A blade of a wind turbine and a method to manufacture the blade are provided. The blade of the wind turbine includes at least one vortex-generator. The vortex generator is constructed and arranged at the blade in a way that it contributes to the aerodynamic characteristics of the blade. The blade includes a recess, which is constructed and arranged to receive at least a part of the vortex-generator. The vortex generator is fixed in the recess. The recess is at least partly arranged and at least partly embedded in a layer of paint of the blade-surface. The recess is established by a former plate, which is arranged on the surface of the blade before the blade-surface is painted and while the recess is established by removing the former plate after the painting is finished.
