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.
