Energy Absorption Study of Metal Composite Foams
In this investigation metal composite foams were produced by casting aluminum melt around hollow ceramic
spheres arranged in steel meshes. Metal composite foams with two types of ordered arrangements and relatively same
density were produced and their mechanical properties were studied by compressive test. Comparison of stress-strain curves
shows that strength to density ratio and energy absorption per unit volume are significantly different. In each arrangement
reproducibility achieved in curves behavior. Arrangement can be used as a parameter in controlling the mechanical
properties in specific direction and may be applied as parameter in energy absorber design.
