Nano Energetic Materials and Microscale Energy Systems

     For densign and preparation of energetic materials, a energetic superlattice material (like-PTFE/Al) and quasi-core/shell structure (Fe2O3/Al-RDX) is designed and fabricated. In order to understand reaction and combustion mechanism, effects of nano-Ag with high thermal conductivity on the combustion wave behavior of Al-CuO MIC were studied. Three stages (ignition, acceleration and steady combustion) of reactive propagation are observed in the combustion process. Furthermore, the pressure loss is important in the combustion process of MIC at microscale environment.
