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 prefabricated fairing for a wind turbine blade comprising fairing lips and exterior and interior fairing surfaces, wherein the fairing has a first fairing state in which the fairing is adapted to be mounted to a blade body of the wind turbine blade and a second fairing state in which the fairing is adapted to be fixed to the blade body, the fairing lips being compressed towards each other in the second fairing state relative to the first fairing state, wherein the fairing is brought from the first fairing state to the second fairing state upon application of a compression force onto the exterior fairing surface at fairing lips, wherein a difference between a first fairing lip distance in the first fairing state and a second fairing lip distance in the second fairing state is equal to or greater than 5 mm.
