Investigating the effects of natural aging on PBXN-111

Abstract. Polymer bonded explosives are commonly used in explosive ordnances owing to their high energy density and safety. However, their stability can be affected by external factors such as the conditions of the storage container and the surrounding environment. The study of the aging process of PBXs is therefore essential to accurately determine their stability and service life. This research investigates the chemical, thermal and mechanical degradation patterns of nine samples of PBXN-111 naturally aged between 3 and 20 years old. The findings of this study led to the conclusion that very little to no degradation was observed in PBXN-111.
