Embodiment Construction
[0034] In the figure, a membrane press 1 for producing components from fiber composite material is shown. In such a film press, components are produced from fiber composite material by deforming a thermoplastic organic sheet material 2 . In this exemplary embodiment, the film press 1 has a press lower part 3 which is designed as a press table on which a mold 4 is arranged as a negative mold for the component to be produced. Furthermore, the press 1 has a press upper part 5 with a cap-shaped pressure tank 6 which can be sealed against the press lower part 3 . For this purpose, the lower circumferential end face 7 of the pressure box 6 which can be placed on the press table is provided with a circumferential seal 8 . A compression cylinder 9 acts on the upper part 5 of the press, wherein, in this embodiment, the piston 10 of the compression cylinder 9 is connected to the pressure box 6 so that the pressure box 6 is pressed to the pressure box 6 by means of the cylinder 9 or the...

Abstract
The invention relates to a method for producing components from fiber composite materials by deforming a thermoplastic organic sheet material (2) in a membrane press (1), wherein a mold (4) is arranged in the membrane press (1) , wherein at least one organic sheet (2) is placed as a workpiece on the mold or to the side of the mold, and wherein the elastically stretchable membrane (11) is stretched pretensioned with the organic sheet (2) connected in between onto the mold (4). In this case, the organic sheet ( 2 ) is deformed while forming the component in that the membrane ( 11 ) is acted upon with a negative pressure on the side facing the mold and with an overpressure on the side facing away from the mold, so that the organic The sheet (2) is formed onto the mould.
Description
technical field [0001] The invention relates to a method for producing a (three-dimensional) component from a fiber composite by deforming a (two-dimensional) thermoplastic organic sheet and a press for producing a component from a fiber composite using the method. Background technique [0002] Within the scope of the present invention, organosheet means a plate-shaped (reinforced) semi-finished product made of fibers embedded in a matrix made of thermoplastic. The fibers can be present as continuous fibers or as long fibers, for example in the form of a fiber fabric or a fiber scrim. The fibers may be, for example, carbon fibers, glass fibers or aramid fibers. Such organic sheets are used as fiber composite materials for the production of components (eg lightweight construction) for aeronautics and space technology (eg aircraft construction) and (eg in automobile construction) transport engineering. Due to the thermoplastic fiber matrix, such organic sheets can be (therma...
