Abstract:
1. A method for producing a multi-dimensionally profiled preform from a pre-impregnated or binder-crosslinked, multidirectional fiber composite material in a forming tool having a top tool component and a bottom tool component, wherein in a closed position the top and bottom tool components define a shaping gap therebetween, the shaping gap being profiled in conformity with the preform, the method comprising the acts of: in a course of closing the top and bottom tool components, re-tightening the fiber composite material while simultaneously retaining a tensioning force via a tensioning frame that envelopes the top and bottom tool components; in order to compensate for excess material in regions where a shaping gap has a weaker profile, increasingly deforming the fiber composite material in the form of a bead, that is formed within a cavity defined by the bottom tool component, in an edge trimming zone of the preform between the shaping gap and the tensioning frame in synchronism with a closing movement of the top and bottom tool components at a start of a material forming process, wherein
