Abstract

The present invention relates to a novel process for the production of novel fibre-reinforced profile materials filled with a rigid foam core, especially a PMI foam core. In particular, the present invention relates to a novel process which, in various versions, provides a particularly high throughput and allows a very wide range of shaping options. One step here continuously produces a complex fibre-reinforced profile material and simultaneously inserts the rigid foam core into same. In addition, in the same process step, very good binding of the rigid foam core to the fibre-reinforced profile material is assured. Shaping further takes place in two or more moulds simultaneously to achieve a particularly high throughput and simultaneously produce profile materials differing in shape.
