The present invention relates to a novel process for the production of novel fiber-reinforced profile materials comprising a rigid foam core, in particular a PMI foam core. In particular, the present invention relates to a novel process which can be carried out in two variants, a short Pul-press process and a Pul-shape process. One step here produces a fiber-reinforced profile material and simultaneously inserts the rigid foam core into same. The same step moreover ensures very good binding of the rigid foam core to the fiber-reinforced profile material.
