Abstract

Abstract

By adopting wedge-shaped charge and using critical thickness to characterize detonation waves propagation, a experimental study was carried out to explore influences of particle size of HMX on detonation waves propagation of HMX and HMX/F2641 at the two different densities of HMX. Experimental results show as follows: (1) Decrease in size of HMX particle results in diminution of critical thickness, namely enhancement of detonation wave propagation capability; (2) HMX/F2641excels HMX in detonation wave propagation capability at the same size of HMX particle; (3) Increase of charge density is advantageous to detonation waves propagation.
