Manufacturing, Heat Treatment and Investigation of Foam-Filled Tubes

Abstract Composite metal foams are hybrid structures with the main advantages of high specific strength and mechanical energy absorption associated low density. In course our research, we successfully manufactured functional EN AC-44200 matrix filled lightweight expanded clay aggregate particles (LECAPs) in AW-6060 alloy tubes a diameter 50 mm wall thickness 5 mm. Manufacturing was performed by low-pressure infiltration directly into aluminium tube. Six different types samples were examined: syntactic foam, in-situ ex-situ their heat-treated pairs. compression tests, heat treatment provided visible improvement results foams.
