摘要： The invention relates to a method for inserting prepreg layers (21, 22, 23) into shaping tools (10) while producing component parts from fiber reinforced composite materials. The inventive method involves the use of a rigid supporting structure (30) having a gas-permeable top side (32) whose outer contour corresponds to the inner contour of the shaping tool (10) for the component part. The wall thickness of the component part is thinner than the inner contour of the shaping tool (10). The interior (31) of the supporting structure (30) is subjected to a pressure that is low relative to the outside pressure. One or more prepreg layers (21, 22, 23) are placed in succession on the gas-permeable top side (32) of the supporting structure (30). The supporting structure (30) with the prepreg layers (21, 22, 23) placed thereon is inserted into the shaping tool (10) in the existence of a low pressure that continues to prevail inside the interior (31) of the supporting structure (30). While doing this, it is ensured that the prepreg layers (21, 22, 23) are arranged between the inner contour of the shaping tool (10) and the outer contour of the top side (32) of the supporting structure (30). Next, the low pressure inside the interior (31) of the supporting structure (30) is discontinued. Lastly, the supporting structure (30) is removed from the shaping tool (10).

摘要： The invention relates to a method for producing a fiber-composite material with one or more fillers added to the resin, in addition to reinforcement fibers added to the resin/filler mixture, whereby, apart from the fibers, ground fiber material as fiber ground material is added to the resin or the resin/filler mixture. The invention also relates to a sheet molding compound with a resin matrix system and reinforcement fibers and optionally fillers, whereby the fillers are ground material of the same material of which the reinforcement fibers are also composed.
