Abstract
The volume of a composite explosive (RDX/binder-83/17) has been measured at temperature 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 3.57 x E4 K super -1 as the mean of 15 measurements having a standard deviation of 0.066 x E4 K super -1. A similar technique applied to an aluminum specimen whose coefficient is known gave a value about 2.0 percent too large.
