The production of microporous syntactic foam by pressure infiltration of sintered preforms of micro glass bubbles with Al‐, Zn‐ and Mg‐alloys was examined. Compression tests with aluminium matrix specimens showed that this material has a very high compression strength and behaves almost like an ideal crash energy absorber. Due to their closed microscopic‐scale porosity such foams can be surface treated e.g. by anodizing processes. The figure shows a cross section of an anodized aluminium syntactic foam.
