Summary:In this study, Zn-Al matrix composite foams reinforced with Al sub(2)O sub(3) short fibers (Al sub(2)O sub(3f)/Zn-Al composite foams) were fabricated with the melt foaming process. The compressive properties and the energy absorption characteristics of the composite foams were investigated. To obtain the failure behaviour, the deformation of the composite foams was observed by scanning electron microscope (SEM). The results show that the microstructures of the foams have a significant effect on the compressive behavior of the composite foams. The strengthen mechanisms of the fiber on compressive properties of the composite foams were presented. Furthermore, the composite foams exhibit a high energy absorption characteristic.
