CONTINUOUS PRODUCTION OF PROFILES IN A SANDWICH TYPE OF CONSTRUCTION WITH FOAM CORES AND RIGID-FOAM-FILLED PROFILE

摘要

The present invention relates to a novel process for the production of novel fibre-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 fibre-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 fibre-reinforced profile material.

主权项

1. A process for continuous production of fibre-reinforced profiles comprising a foam core, the process comprising:
a) introducing foam cores and connecting a newly introduced foam core to an end of the most recently introduced foam core; b) wrapping a fibre material around the foam core; c) impregnating the fibre-material wrap with a resin; d) optional optionally moulding the wrapped foam core in a first mould; e) heating and thereby optionally hardening the resin in a second mould; f) cooling the wrapped foam core in a third mould; and g) separating individual profiles by cutting or sawing and removing the finished workpiece, wherein the second and third mould are moved in respectively mutually opposite direction on carriages.
