Abstract: Metal Matrix Syntactic Foam (MMSF) is a novel type of porous composite material comprising hollow microspheres and a metal matrix. In comparison to conventional foam materials, MMSF exhibits superior properties, including low density, high specific strength and excellent energy absorption. Its density can be tailored to align with the pore structure, rendering it an optimal choice for absorbing and dispersing impact loads. Consequently, MMSF holds immense potential for applications in the aerospace, automotive and construction industries. This paper outlines the current research status of the selection of MMSF matrix materials and preparation process. It also analyses the influence law of matrix selection on the properties of MMSF specimens, such as density, compressive strength and energy absorption capacity. This can provide a reference for further research on MMSF.
