Claim Text:
1. A method for producing a fiber composite component, the method comprising: introducing an elastic core sleeve into a prestressing mechanism, wherein the elastic core sleeve comprises a closed end and an open end; fastening a turned-back edge of the elastic core sleeve by a clamping ring on an outer circumference of the prestressing mechanism, wherein the clamping ring prevents air from escaping between an outer side of the core sleeve and the prestressing mechanism by clamping action during activation of the prestressing mechanism; expanding the core sleeve that is introduced, for elastic prestressing of the core sleeve, by activating the prestressing mechanism, wherein the prestressing mechanism is divided lengthwise into a lower part and an upper part for opening the prestressing mechanism along its length to place the core sleeve therein; wherein the lower part and the upper part form a closed first end; wherein the prestressing mechanism is provided with a channel adapted to be connectable to a vacuum pump, wherein the channel is located at a rear of the prestressing mechanism and in a longitudinal direction of the prestressing mechanism and is formed by mating of the upper and lower part together, and wherein the closed first end is perpendicular to the channel; wherein the lower part and the upper part form an open second end to introduce the core sleeve through the open second end and place the core sleeve inside the prestressing mechanism, and wherein a vacuum on an outer surface of the core sleeve is produced by the vacuum pump connected to the channel for expanding the core sleeve by the prestressing mechanism when the prestressing mechanism is activated; introducing a dimensionally stable core body through an opening of the expanded core sleeve, wherein the dimensionally stable core body is formed as a one-piece with a desired shape; releasing the expanded core sleeve by deactivating the prestressing mechanism, to snugly enclose the core body, which comprises the desired shape, with the core sleeve to form a molding core comprising the desired shape of the core body; and at least partly laying at least one semi-finished fiber product on the molding core that is formed, to shape the fiber composite component to be produced.
