Abstract

During the course of this inquiry, an attempt has been made to understand the thermal decomposition characteristics and burning rate of ammonium perchlorate working as an oxidizer and polyvinyl chloride functioning as a fuel binder for high energy-carrying composite materials. The samples were examined for material morphology and elemental composition by scanning electron microscope and dispersive energy X-ray spectrometer methods. In addition, a NETZSCH simultaneous thermal analyzer comprising a differential scanning calorimeter and a thermogravimetric analyzer has also been utilized to ascertain the thermal decomposition method associated with each composition. The thermal decomposition process of the energy-carrying composite materials consisted of three distinct stages, and the mass loss rate during this process ranged from 100 °C to 500 °C, accounting for 99% of the sample mass. The enhanced catalytic activity of Fe2O3 in ECCMs significantly lowers the exothermic decomposition temperature and increases the total heat release. Besides, the burning rate studies have been conducted at ambient and different pressures with and without Fe2O3, providing valuable insights into the combustion behavior of ECCMs under varying conditions.

Keywords
