Abstract : A method of determining shock Hugoniots of opaque media by means of microwave interferometry is described. This method has been used to determine shock Hugoniots for solid propellants, propellants with dummy oxidizer, and inert binders. It was found that the shock response of solids-filled elastomeric polymers is the same as that of the continuous phase along, at loadings as high as 75 wt. % solids. It was also found that ammonium perchlorate decomposes exothermally under shock, even in nondetonable propellants; and because of this decomposition, truly non-reactive shock Hugoniots cannot be obtained on live-oxidizer formulations, at least not at shock strengths above 10 kbars.
