Abstract

Abstract

The ability to accelerate metal plates of aluminized explosives containing micrometer and nanometer aluminum powder has been investigated experimentally with a VISAR interferometer. In the case of nanometer aluminum powder, the free surface velocity of metal plates was larger and the reaction time was decreased by 35.1% compared with that in the case of normal aluminized explosives. The influence of morphology of oxidizer AP on aluminized explosive performances was explored. The ability of the aluminized explosive made from RDX/Al composite with physical-chemical method was larger and its detonation reaction time was shorter than that made with mechanical mixing. When RDX in the aluminized explosive was replaced by an oxygen-enriched explosive, a 10% higher metal plate velocity resulted.
