In this study, the low-velocity impact behavior of porous metal matrix composites (MMCs) has been investigated. The MMCs consisting of spheroidal cast iron chips (GGG-40) and bronze chips (CuSn10) were produced by hot isostatic pressing. The MMCs were produced with different CuSn10 contents as 90–80–70–60%. The hot isostatic pressing was performed under three different pressures and temperatures. The produced MMCs were exposed to low-velocity impact loading under 2 m/s by using a drop weight test stand. The test results were compared with the bulk CuSn10 and bulk GGG-40, separately. The test results revealed that hot-isostatic-pressed MMCs can successfully represent bulk material properties when subjected to low-velocity impact loading even these MMCs have porosity 2–8%.
