Abstract
This paper shows the results of chemical compatibility of two types of propellants (NGB-051and NC-28) with two types of polymer materials (Polyamide 12 and Polymethylmetacrylate) by different test methods. Testing was performed using heat flow calorimetry, differential scanning calorimetry, the method of chemical analysis after aging and vacuum stability test method according to STANAG 4147. The heat flow curves of propellants, polymeric materials and their mixtures and the theoretical curves were determined. Produced energy was calculated and the values of relative and absolute compatibility were determined. Analysis of the exothermic peak of decomposition of propellants and its mixture with polymer materials was performed and the maximum difference in peak temperatures was calculated. The stabilizer content of the unheated propellants, the artificially aged propellants and the propellants after heating in contact with the polymer material was determined. The values of the volume of released gas, by using vacuum stability test method, for the propellants and polymer materials as well as their mixtures were determined. The value of absolute compatibility was calculated. Compatibility was estimated on the basis of the results presented.
