    Abstract
  • Two charge samples of same composite and shape, but one with and the other without an aluminum interlayer, were prepared following the designated inner/outer composite charge. The expansion process of the aluminum interlayer was determined by X-ray technology, and the difference in the driving capability between the two charges were compared using the high speed scanning and the cylinder test. The results show that the detonation wave does not change obviously due to the similar impedance. The detonation products of the inner and outer charges can be divided by the interlayer when the relative specific volume is below 3.0. However, the driving ability is not affected and the ratio of the specific kinetic energy of the two charges is gradually close to the ratio of the two effective charging masses.
