- Abstract
The objective of this work was to characterize mechanical properties of composite solid propellant in order to conduct the structural integrity assessment of propellant grain. Data required for analyses regarding loads experienced during rocket motor transportation and flight were obtained. Based on time and temperature superposition, master curves were constructed from propellant mechanical properties determined by dynamic mechanical analysis. These curves can be used as input in finite elements analysis software, demonstrating the applicability of the proposed methodology.
