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. A mold is used which is permeable to air at least in some areas and which is produced, for example, from porous aluminum.
