Abstract

Abstract

The pressure history curves of aluminum fiber explosive and traditional aluminized explosives were measured by air blast experiments, and then the peak pressure, the secondary shock wave, the time of positive phase and the impulse were obtained by analyzing the curves. The result show that the peak pressure of the aluminum fiber explosive is not improved obviously with regard to the matrix explosives (RDX). The pressure decay rate of the aluminum fiber explosive is slower than that of RDX, resulting in that the time of the positive phase of the aluminum fiber explosive is longer than that of RDX. Compared with RDX, the impulse of the aluminum fiber explosive increases on the average by 18%, close to that of the traditional aluminized explosive. The amplitude and the occurrence of the secondary shock wave of the aluminum fiber explosive are the same as the traditional aluminized explosives and the secondary shock wave of aluminum fiber explosive occurs earlier than the matrix explosives (RDX), which shows that the amplitude and the occurrence time of the secondary shock wave are correlated with the types of explosive.
