Abstract

The invention relates to a method for producing molded parts from fiber composite material, including the following steps: a) providing a press having a first press tool, a second press tool and a membrane. The first press tool and the second press tool are movable relative to each other. The membrane is connected to one of the press tools, a cavity for a working medium being formed between the membrane and the press tool connected thereto, a working chamber for a workpiece being formed in the other press tool, and the volume of the working chamber being modifiable by a movement of the membrane when the press is closed, b) providing at least one workpiece having a workpiece volume. The workpiece has a matrix and fibers inserted therein, c) inserting the workpiece into the working chamber of the press, d) closing the press. The working chamber takes up a first volume, e) applying pressure and/or temperature to the workpiece by means of the membrane. The working chamber takes up a second volume, a hardened molded part being created from the workpiece, and f) opening the press and removing the molded part. In order to ensure continuous and uniform pressure distribution, according to t…
