Abstract In this study, two novel zinc syntactic foams are tested in dynamic and quasi-static compression. Expanded perlite (EP) and expanded glass (EG) particles are combined with the ZA27 zinc alloy using counter-gravity infiltration casting. The average densities of the resulting EG-ZA27 and EP-ZA27 syntactic foams are 1.84 g/cm3 and 2.05 g/cm3, respectively. The as-cast foam samples are compressed under quasi-static (0.1 mm/s) and dynamic (284 mm/s) loading conditions. Optical and infrared imaging are used for a detailed investigation of their deformation behaviour. The increasing brittleness of the ZA27 alloy at high strain rates is found to alter the syntactic foam properties at dynamic loading.
