Abstract

Metal-organic Framework (MOF) was selected to fabricate three typical nitramine explosives (RDX, HMX and CL-20) based core–shell structure composites. The results showed that the decomposition peak temperature of the three typical energetic materials after being wrapped by the MOF material had advanced, while the activation energy value has increased significantly. The impact sensitivity and the friction sensitivity have decreased a lot, indicating that the stability has been further enhanced after wrapped with MOF. In addition, software simulation proves that the addition of MOF material will not affect the detonation performance of the original energetic material, which means these composites can still maintain a better energy performance.
