The Influence of Al/AP on the Detonation Performance and Energy Release of Composite Explosive

Jiajia Yan

Abstract

The detonation parameters of RDX-based composite explosive,such as the detonation pressure,detonation velocity,detonation heat and detonation volume,were obtained by experiment and experimental calculation method.The influence rules of Al/AP mole scale on the detonation performances of composite explosive and detonation energy release were analyzed,and the correlative experimental calculation formula was deduced.The results showed the detonation heat and work capability factor decreased,while the detonation pressure,detonation velocity and detonation energy transformation efficiency increased with the Al/AP mole scale increasing.
