Claim:
1. Method for producing a layered semi-finished product for further processing into fibre-reinforced composite components in a consolidating tool, the layered semi-finished product comprising a layer sequence having at least one layer of an unconsolidated fabric of reinforcing fibres and at least one layer having one or more metallic inserts, wherein the layer sequence is arranged, at reduced pressure, between a top film and a bottom film both films made from thermoplastic matrix material, said films are connected to each other along their periphery in a pressure-retaining manner, and wherein the layered semi-finished product is bent in one or more places according to a tool shape of the consolidating tool, wherein at least one of at least one resulting bend runs through at least one of the metallic inserts, the method comprising the steps: a. arranging the layer sequence between the top film and the bottom film made from thermoplastic matrix material, b. subsequently to step a., connecting protruding edges of the top film and the bottom film made from thermoplastic matrix material with one another, c. evacuating a volume between the top film and the bottom film made from thermoplastic matrix material, and d. deforming the semi-finished product such that a once or multiple times bent form of the semi-finished product according to the tool shape of the consolidating tool is generated, wherein at least one of at least one resulting bend runs through at least one of the metallic inserts, wherein steps b. and c. are carried out before step d. in any desired sequence, simultaneously or overlapping in time.
