Process Window for the Embedding of Eccentric Steel-Reinforcing Elements in the Discontinuous Composite Extrusion Process

Abstract:

The process of discontinuous composite extrusion offers the possibility for the centric and eccentric embedding of steel reinforcing elements into an aluminium profile. Thereby, the process is influenced by various parameters, which can lead to certain types of processes failures. Three characteristic types of process failures – cavities, local plastic deformation and rotation – have been identified. According to these influencing factors and based on the process window for the discontinuous centric embedding of cylindrical reinforcing elements in rods, a process window for the eccentric embedding of steel reinforcing elements was developed.
