摘要

This paper summarizes three major efforts that have recently been conducted to further the insight regarding the thermal decomposition characteristics of AP and an AP-based composite propellant at temperatures less than 270 C. The studies utilized various techniques to evaluate the thermal decomposition of neat AP as a function of time, particle size, temperature and crystal structure. For all samples, the nature of the physical processes is probed by the use of SEM and optical microscopy. The nature of the chemical processes is elucidated by analysis of the time-dependent behavior of the weight-loss curves, the product identities and the time-dependent behavior of the gas evolution rates of the products. The thermal decomposition characteristics of an AP-based propellant are evaluated as a function of time and temperature and compared to that of the analogous neat-AP decomposition experiments. Insight into the complex and coupled decomposition processes is obtained and is relevant to developing a capability to predict the response of these materials in a slow- cookoff environment.
