The kinetic analysis of a heavily aluminized cyclotrimethylene-trinitramine (RDX) using differential scanning calorimetry (DSC) is conducted. The Friedman isoconversional method is applied to DSC experimental data and AKTS software is used for the analysis. The preexponential factor and activation energy are extracted as a function of product mass fraction. The extracted kinetic scheme does not assume multiple chemical steps to describe the complex response of energetic materials; instead, a set of multiple Arrhenius factors is constructed based on the local progress of the exothermic reaction. The resulting reaction kinetic scheme is applied to two thermal decomposition tests and a shock initiation test for validating the reactive flow response of a heavily aluminized RDX.
