Thermal analysis of some propellants and explosives with DSC and TG/DTA (U)
report
At the request of DMKL, project A95KL486, an investigation was performed to characterise thermally some explosives and propellants by standard thermal analysis. The used techniques are Differential Scanning Calorimetry (DSC) and the combined technique Thermogravimetry and Differential Thermal Analysis (TG/DTA). According to STANAG 4515, thermal analysis is a technique used to determine some thermal characteristics of explosives, such as onset temperature, enthalpy and heat capacity measured by DSC. The change in weight as a function of the temperature is determined by TG/DTA.
Another technique mentioned in STANAG 4147 to assess compatibility is thermal analysis by using DSC or TG.
In this report, the compatibility of a propellant with some polymers is investigated. The critical parameter to assess compatibility by DSC is the onset temperature and in the TG experiments, the weight loss determines the compatibility.
