A Method for the Determination of Thermal Conductivity of Propellant Materials by Differential Scanning Calorimetry.

Abstract

Benzoic acid, polymethylmethacrylate, polytetrafluoroethylene, and X-14 (a high energy, double-base propellant) were heated through decomposition and their thermal analysis curves compared. X-14 undergoes a pyrolytic decomposition beginning at 413 deg K and peaking at 573 deg K. The thermal conductivities of small samples of propellant and polymer were calculated from measurements of their rate of heat flow into a heat sink in a modified Differential SCANNING Calorimeter. This method will permit thermal conductivity measurements in small samples of sensitive materials, thus reducing hazards in their handling, and giving the first measurement on some very sensitive materials.
