Method for producing a structural component, particularly for a vehicle body

The invention relates to a method for producing a structural component (B, B'), particularly a structural component for a vehicle body, according to which method a flat carrier material (T1, T2, T3, T4) made of metal, thermoplastic material and/or fibre-reinforced thermoplastic material is shaped into a three-dimensional component, and according to which the carrier material (T1, T2, T3, T4) is furnished with support material (S, S') made of thermoplastic material, such that the carrier material and the support material form a materially bonded material composite. In order to reduce the number of production steps in such a method and increase the productivity of the method, according to the invention the material composite constructed from the carrier material (T1, T2, T3, T4) and the support material (S, S') is produced before the carrier material (T1, T2, T3, T4) is shaped into the three-dimensional component (B, B'), the material composite (W) is heated before the shaping in order to allow a shaping of the thermoplastic material, a rib structure (RS) is impressed into the support material (S, S') during the shaping of the material composite, and the three-dimensional component (B, B') having the rib structure (RS) is temperature controlled, preferably cooled.
