Abstract
ABSTRACT In this paper, we produced KP-aluminum composites using a solvent/non-solvent technique to improve their combustion properties, tested different process parameters for better bonding, and analyzed their thermal decomposition and ignition combustion. The optimum refinement and binding for the samples was found using a 1:4 solvent ratio, dichloroethane as the non-solvent, a 40℃ water bath and 300 rpm stirring. The refined KP improved the heat transfer and the reaction of the aluminum powder. In combustion tests, the refined sample had 1.2 times higher pressure, 50% shorter ignition delay and better combustion rates and completeness than the unrefined mixture, showing that the refined KP significantly improves the reaction of the system. The morphology of KP was improved by solvent/non-solvent methods to achieve micro-nanometer particle sizes, which resulted in a significant reduction of the dispersion scale of the mixed system of KP and Al, facilitated the reaction of KP on aluminum powder, and improved the combustion exothermic performance of the whole system.
