Abstract
Energetic Materials are explosive agents that generate large amounts of hot gases by an exothermic reaction without the need for atmospheric oxygen. Therefor the oxidizer must be available in form of molecularly bound functional groups or in form of discrete salts (e. g. ammonium perchlorate) containing oxygen. Modern solid propellants are highly filled composite materials consisting of a polymeric binder in which crystalline oxidizers the filler are incorporated in amounts of up to 90 wt.%.
Background of the performance of a composite propellant are micromechanical phenomena. Therefore, the understanding of micromechanical phenomena like matrix filler detachment, distribution of filler, crosslinking, chain scission and micromecanical deformation mechanism is the key to the understanding of the behaveor of composite propellants. These micromechanical phenomena influence the sensitivity to impacts during transportation and ignition and the combustion behavior. The performance of composite propellants is correlated with its mechanical properties.
