Introduction
Composite metal foams (CMFs) are hybrid structures in which the foam structure can be interpreted as a composite (the metallic matrix contains hollow particles). The main advantages of CMFs are their low density, high specific strength and outstanding mechanical energy absorption. The proposed research would deal with the production of CMFs (Work Package 1, WP1), including their mass production by die casting, their application as stiffeners and energy absorbers in sandwich panels, tubes and other opened or closed hollow sections and their joining technologies (by materials, e. g. brazing and welding. During the development of CMFs, the traditional strengthening methods have reached their limits; therefore, novel techniques like reinforcement of the matrix (WP2, by particles, short fibres or composite wires) or the modification of the fillers (WP3, non-spherical fillers) would also be studied in detail. Last but not least, the recycling of the CMFs is a serious question. Therefore, the WP4 is devoted to investigating the recyclability of the CMFs, including remelting and production of CMFs from the recycled materials. For the successful fulfilment and complete understanding of the above-mentioned aims, extensive microstructural and mechanical tests and their critical evaluation are needed and planned. As a result, a better understanding, as well as the broadening of the beneficial application possibilities of CMFs is expected.
The MTA-BME Lendület „Momentum” High-performance Composite Metal Foams Research Group is established to explore new materials and relationships in the field of CMFs for diverse structural applications.
