Abstract
The growing acceptance of composite explosives has made their careful characterization of prime importance. Thermal conductivity is one of the properties required in the heat-transfer analysis of military stores. A simple commercial apparatus, based on the Lee's Disc method, was successfully modified and improved for use with composite explosives. The technique depends on careful analysis of transient heat transfer phenomena. Calibration with two standards indicates that the apparatus is accurate to ~ 5% or better. The thermal conductivity of a composite explosive appears to be a strong function of the binder's value and a relatively weak function of the thermal conductivity of the solid constituents. Measured values for current DREV composite explosives varied between 3.85 x 10 to the power of minus 4 and 4.75 x 10 to the power of minus 4 cal-cm/square cm-oC-sec.
