The invention concerns a process for the production of a mold core for the one-part production of wind power installation rotor blades. According to the invention the method includes the steps: providing a flexible hollow body, for example a film tube, inserting the hollow body between at least two mold portions which are so arranged relative to each other that they form a negative shape of the rotor blade to be produced, filling the hollow body with loose material prior to or after insertion of the hollow body between the mold portions, and producing a reduced pressure in the hollow body after it has been filled and inserted in such a way that the hollow body solidifies. The invention further concerns a process for producing a reduced pressure between mold portions and mold core. |
