The effect of a new organo-copper burn rate catalyst on the aging properties of an HTPB/AP based composite propellant has been studied and compared with a similar propellant containing copper chromite. The degradation of the propellant surface under conditions of thermo-oxidation was studied by monitoring oxygen uptake using a gravimetric technique. The oxidative induction times for the reaction were determined for a series of elevated temperatures and the data used to predict the storage life of the propellant at ambient temperatures using an Arrhenius plot. It was shown that the storage life of a copper chromite propellant was approximately 7.5 years at 20 deg C while the corresponding organo-copper propellant had a storage life of approximately 49 years.
