General Topic V: Virtual poster session


Composite metal foams (CMFs) are hybrid structures which are usually produced individually, and not as a functional, structural parts. Functional composite metal foams are characterized by high strength, high rigidity and extreme energy absorbing properties compared to conventional metallic foams, which allow them to be used as load-bearing materials and energy absorbing elements.

Specimens are made in circular hollow sections with the wall thickness of 5 mm. For proper comparison, Si alloyed casting Al alloy was used. To ensure the required porosity lightweight expanded clay particles (LECAPs) with the same chemical composition, but different average sizes were used for the production. Functional CMFs were produced by inert gas pressure infiltration with bimodal diameter distribution of the LECAPs in which the particles have the same chemical composition, but different nominal diameter.

The breakthrough of this research would be the successful production of low-cost unimodal and bimodal functional CMFs, which have never been reported or investigated in details previously. Besides their low density, these CMFs would possess high strength, high toughness and special, functional properties compared to simple metallic foams.

During the evaluation of the research project, the following main question will be answered: Is it possible to create low-cost functional CMFs? In the framework of this research, sandwich structure CMFs and new groups of materials are developed with tailored properties. In addition to the basic mechanical investigations, the focus is primarily on the basic research of the mechanical properties in radially constrained strain condition.
