Outline
Based on the aged solid high explosive, a series of experiments were performed to study the influence of thermal aged on the detonation performance for JOB-9003 explosive. The physical and detonation performances were contrasted for the new and aged explosive samples. The results indicated that the quality and density of the sample have a slight decrease, and the inner and outer diameter of the sample have a slight increase after 180 d aging. It was also found that the time gap defining as the gap between detonation-wave propagating at the outer surface is very small. The only change is that the detonation wave velocity has a slight decrease for the aged samples. Therefore, it could be affirmed that the detonation performance is not changed obviously by accelerated aging 180 d.
