Aluminum nanopowders (nmAl) coated with oleic acid (OA) were obtained under nitrogen atmosphere, and their surface morphologies and structures were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy. The thermal decomposition reaction kinetics of composite systems, nmAl/hexogen (RDX) and (nmAl + OA)/RDX, were investigated using differential scanning calorimetry (DSC). Their kinetic parameters and kinetic equations were obtained. The results showed that most of the OA adsorbed on the aluminum nanopowder surface by physical adsorption. Only a small amount of OA reacted with the surface aluminum atoms and adhered to the surface via chemical bonds. Compared with the nmAl/RDX composite, the peak temperatures for the (nmAl+OA)/RDX composite at multiple heating rates were lower. The apparent activation energy (E_a) and pre-exponential factor (A) of the main decomposition reaction were 141.18 kJ·mol^-1 and 10^12.57 s^-1. The reaction mechanism fits a three-dimensional diffusion mechanism and obeys the Jander equation with n= 1/2. The kinetic equation can be expressed as: dα/dt=10^13.35(1-α)^2/3[1-(1-α)^1/3]^1/2e^-16981.0/T.
