The reinforcement of composite aluminium extrusions offers a high
potential regarding weight reduction and improvement of mechanical
properties which is essential for components in lightweight constructions.
The current work gives an overview of the quasi-static properties of spring
steel wire reinforced EN AW-6082 with varying reinforcing ratio. The
deformation and damage behaviour is investigated in detail for a
reinforcing ratio of 11.1 vol.-%. It is shown that the relatively ductile
behaviour of the spring steel wire leads to multiple necking resulting in
higher strains than expected. Current models are expanded and modified
for a proper adaptation to the material system.
