Abstrak

In the present work, an attempt has been made to unveil the effect of micro- and nano-particles of copper oxide (µCuO and nCuO) on the thermal decomposition of composite solid propellants (CSPs) based on ammonium perchlorate, hydroxyl terminated polybutadiene and binary fuel mixture of aluminum and lithium tetrahydridoaluminate (AP/HTPB/Al+LiAlH4). The prepared CSPs were analyzed by different analytical techniques. The second part of the study was devoted to the kinetic modeling of the thermal decomposition process of the fabricated CSPs samples. In the light of the obtained results, it was concluded that the use of µCuO and nCuO accelerated the decomposition of CSPs. Moreover, the incorporation of nCuO to the LiAlH4-based propellant increased substantially the heat release and decreased the average activation energy compared to the baseline samples. Moreover, the decomposition reaction mechanisms of the investigated propellant samples have clearly changed through the incorporation of nano- and micro-CuO.
