Shock Equation of State of Single Constituent and Multi-Constituent Epoxy-Based Particulate Composites

ORAL

Abstract

There are several studies in the literature regarding the equation of state of alumina-epoxy composites. Although these single component systems interact in a complex manor with shock waves, the addition of a second metal or ceramic particulate can result in even more complex interactions. This paper presents a review of shock loading studies on epoxy-based particulate composites, such as Al$_{2}$O$_{3}$-epoxy, Al-Fe$_{2}$O$_{3}$-epoxy, and, Al-MnO$_{2}$-epoxy. Comparisons between measured ultrasonic sound speeds and shock bulk sound speed are discussed. Finally, the relationship between equation of state parameters and particulate concentration is investigated.
