Abstract
A method of repairing a wind turbine blade is described. The blade comprises a shell body comprising a fibre-reinforced polymer material. The blade is strengthened by use of a UV curable prepreg material having a first side and a second side. The method comprises the steps of: a) applying the UV curable, fibre-reinforced prepreg material to an area of application on an outer surface or an inner surface of the wind turbine blade with the first side of the prepreg material facing the area of application, and b) exposing the prepreg material to UV radiation for a predetermined amount of time so as to allow the prepreg to cure.
