  • Patent number: 10843418
    Abstract: The invention relates to a press for producing a component from a fibre-composite material, which is designed as a membrane press, comprising a press frame (15), a press lower part (3) on which a mould (4) is arranged, a press upper part (5) having a pressure chamber (6) that can be sealed against the press lower part (3), one or more press cylinders (9) which are supported on the press frame and act on the press upper part (5) and/or the press lower part (3), a membrane (11) that can be tensioned over the mould (4), a vacuum pump (12) with which a vacuum can be generated on a side of the membrane (11), for example on the underside, characterised in that the press frame is designed as a C-frame with an upper horizontal C-arm, a lower horizontal C-frame and a vertical C-base.

  • Publication number: 20190016039
    Abstract: The invention relates to a method and a press for producing a component from a fiber composite material by deforming a thermoplastic semi-finished product, in particular an organic sheet (2), in a membrane press (1), wherein a mold (4) has been or is arranged in the membrane press (1), wherein at least one semi-finished product/organic sheet (2) is positioned on top of or against the mold as a workpiece, and wherein an elastically stretchable membrane (11) is preloaded while stretched over the mold (4) with the semi-finished product/organic sheet (2) arranged therebetween. At the same time, the semi-finished product/organic sheet (2) is deformed in order to form the component, in that a vacuum is applied to the membrane (11) on the side facing the mold and a positive pressure is optionally additionally applied to the membrane on the side facing away from the mold such that the semi-finished product/organic sheet (2) is shaped onto the mold.
