Composite extrusion aims at the improvement of mechanical properties of extrudates by embedding continuous reinforcing elements into a profile using a modified porthole die. The extrusion of non-symmetric reinforced profiles is a challenge, as the material flow has to be homogeneous. Die shape optimization for the production of non-symmetric reinforced profiles was investigated. The optimization phase took into account the process conditions aiming at a localized homogenization of the material flow to avoid profile distortion. The reinforcement effect on the material flow was analyzed by numerical investigations. The numerical results were verified by experiments. (C) 2014 Elsevier Ltd. All rights reserved.

Abstract
Composite extrusion aims at the improvement of mechanical properties of extrudates by embedding continuous reinforcing elements into a profile using a modified porthole die. The extrusion of non-symmetric reinforced profiles is a challenge, as the material flow has to be homogeneous. Die shape optimization for the production of non-symmetric reinforced profiles was investigated. The optimization phase took into account the process conditions aiming at a localized homogenization of the material flow to avoid profile distortion. The reinforcement effect on the material flow was analyzed by numerical investigations. The numerical results were verified by experiments. (C) 2014 Elsevier Ltd.
