Foamed combustible material based on polymer bonded RDX was fabricated using CO2 asfoaming agent. The inner structures of felted and foamed combustible materials werepresented by SEM. The two materials presented different formulations and inner porousstructures. The combustion behaviors of felted and foamed materials were investigated byclosed vessel test. Simultaneously, the co-combustion behavior of combustible cartridgecase with 7-perf consolidated propellants was also investigated. The results of closed vesseltest is applicable to gun system which is made of the foamed combustible material ascomponent.
