Abstract
In this study, the interpenetrating phase composites (IPC) foams were fabricated by infiltrating epoxy resin (EP) and fly ash cenosphere (FAC) into porous aluminum network. A comparison study among the compressive properties and energy absorption characteristics of the EP, the IPC and the IPC foams was carried out. As a result, among the experimental materials, the IPC show the highest compressive strength and energy absorption capacity. Owing to FAC addition, the IPC foams exhibit higher energy absorption efficiency than the IPC. In addition, the compressive strength and energy absorption capacity of the IPC foams are depending on FAC content. These different mechanical properties were investigated and explained by diverse failure mechanisms.
