Abstract: A wind turbine blade includes a leading edge protection element attached to the leading edge of the wind turbine blade. The leading edge protection element extends in a longitudinal direction between an outboard end and an inboard end and includes an attachment surface mounted to an exterior surface of the blade, an exterior surface opposite the attachment surface, a first section extending from the leading edge and along a part of the pressure side of the wind turbine blade to a first transverse end at a first position on the pressure side of the blade, and a second section extending from the leading edge and along a part of the suction side of the wind turbine blade to a second transverse end at a second position on the suction side of the blade.

Abstract: The present invention relates to a method of manufacturing a fibre-reinforced part (50) for a wind turbine blade (10). The method comprises the steps of providing a first layer (57), the first layer comprising a thermoplastic elastomer; arranging a second layer (56) on top of the first layer (57), the second layer (56) comprising a fibre material; and heating the first layer (57) and the second layer (56) to a temperature of 35-90° C. The heated first and second layers are then contacted with a liquid epoxy resin or a liquid mixture of epoxy resins. Subsequently, the epoxy resin is cured to adhere the first layer (57) to the second layer (56) to obtain the fibre-reinforced part.

Abstract: A leading-edge protector element for protecting a leading-edge of a wind turbine blade is provided. The leading-edge protector element includes a film layer and a rubber layer, and is provided on a coiled-up roll. The leading-edge protector element has a thickness between a first edge, a second edge, a third edge, and a fourth edge. The thickness decreases along a transverse direction towards the third edge and towards the fourth edge. The leading-edge protector element for protecting a leading-edge of a wind turbine blade may alternatively only include a rubber layer and also be provided on a coiled-up roll.
