The present invention relates to a method of manufacturing a wind turbine blade having a first member with a first joining surface and a second member with a second joining surface. The method includes applying at least one resin barrier to one or both of the joining surfaces, and subsequently locating the first and the second members adjacent each other so that they are joined by the at least one resin barrier. Hereby at least one cavity is formed between the first and second joining surfaces, which cavity is delimited by the at least one resin barrier. Subsequently resin is filled into the at least one cavity, and the resin is cured. The first member may be a blade shell, and the second member may be a blade spar.

The present invention relates to a method of repairing a fiber composite solid member having a locally deteriorated surface area, such as having cracks or creases. The solid member may e.g. be a mold for the manufacturing of wind turbine blades or such blades. The method comprises 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. At least some of the 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.
