Title:
Chemical Structural Aging Studies on an HTPB Propellant

Abstract:
An accelerated aging study has been performed with an HTPB hydroxy terminated polybutadiene propellant having formulation number TP-H1139. An aging model has been suggested to describe the aging effects on the chemical reaction kinetics in the binder and the resulting mechanical properties. The aging model has been used to make long time equivalent aging properties predictions from short time thermally accelerated aging results. To accomplish the development of an aging model, measurements were made to determine the reaction chemistry in the binder and the corresponding mechanical properties. It was necessary to separate the binder from the solids in the cured propellant and to perform chemical analyses on the sol and gel fractions of the binder.
