摘要：
A vacuum blanket (11) for covering a wind turbine component (12), wherein the vacuum blanket (11) comprises
- At least one vacuum unit (113) for a vacuum assisted arranging (1511) of the vacuum blanket (11) and the wind turbine component (12);
- At least one cross linking support device (114) for initiating and/or for supporting a cross linking of cross linkable adhesive which is arranged between the vacuum blanket (11) and the wind turbine component (12).
In addition to the vacuum blanket (11), method for manufacturing an arrangement (1) of a vacuum blanket according to one of the claims 1 to 11 and a wind turbine component (12) with following steps:
a) Applying of at least one precursor material (1312) of the adhesive material (1311) onto a component surface (121) of the wind turbine component (12);
b) Bringing together the vacuum blanket (11) and the wind turbine component (12) such that the precursor material (1312) is enclosed by the vacuum blanket; and
c) Transforming of the precursor material (1312) into the adhesive material (1311);
wherein during the step b) and/or during the step c) an application of vacuum with the aid of the vacuum unit is carried out for a vacuum assisted arranging of the vacuum blanket and the wind turbine component.
Preferably, a precursor material with at least one curable resin is used and the transforming comprises a temperature regulated curing of the resin. The wind turbine is preferably a wind turbine blade. With the vacuum blanket a safe repair of the wind turbine blade is possible.
