1. A method of repairing a fibre composite solid member having a locally deteriorated surface area, the solid member including one of a wind turbine blade or a mould used to form the wind turbine blade, and the method comprising:
machining a surface section comprising the locally deteriorated surface area in order to obtain a recess having a predefined depth and circumferential shape placing a repair patch having a predefined thickness and circumferential shape matching the recess in the recess, and fastening the repair patch to the solid member by use of a binder material, such that the repair patch remains in the recess, in which method elastic and thermal properties of the repair patch and the binder material are so that after fastening, the repair patch and the binder material in combination have elastic and thermal properties which are substantially the same as the corresponding properties of the surface section before machining, and manufacturing the repair patch on a corresponding position on a plug which was used to model the solid member from, the plug defining a replica of at least a portion of the wind turbine blade and having the shape, dimensions, and surface finish of the at least a portion of the wind turbine blade, the plug having been manufactured before using the plug to form the mould.
