Abstract

IntroductionReactive Structural Materials (RSMs) are a relatively new group of materials designed to have structural strength and store energy to be released at a desired time. Their typical applications are expected in such systems as kinetic penetrators, reactive fragments, reactive bullets, reactive armor, and munition casings. Considering that most structural components in various munitions are based on steel, the utility of RSMs can be semi‐quantitatively assessed from a diagram shown in Figure . The horizontal axis shows a mass fraction of a munition taken by an explosive charge. It is assumed, for simplicity, that the charge is TNT (trinitrotoluene) with the rest of the munition comprised of a metal casing, made of either steel or aluminum. Upon initiation, the case is assumed to oxidize releasing heat in addition to the heat generated by the TNT charge. The percentages of heat released by both TNT and case oxidation are shown for hypothetical scenarios with cases made of steel or aluminum. The estimate shows that for the common mass percentage of the explosive charge, around 30%, the heat release due to the combustion of the metal case can add from ca. 40 to 70% of the total chemical energy produced by
