A Castable Composite Explosive: The Coefficient of Cubical Expansion,

Abstract

The volume of a composite explosive (RDX/binder-83/17) has been measured at temperatures from 248 to 338 K using Archimedes' principle. The specimens were covered with a protective film specially developed to prevent the binder from dissolving in the fluid, a silicone oil. From the results the coefficient of cubical expansion of the explosive at 296 K is .000357/K as the mean of 15 measurements having a standard deviation of .0000066/K. A similar technique applied to an aluminum specimen whose coefficient is known gave a value about 2.0 percent too large. (Author)
