On Elastic-Plastic Explosives for Explosive Hardening

Article Preview

Abstract:

In order to improve the effect of explosive hardening and reduce the production cost, the elastic-plastic explosive which consists of RDX, rubber, deterrent, antioxidant and plasticizer was prepared. The experiments including density testing, detonation performance, detonation velocity testing, impact sensitivity, and explosive hardening were carried out. The results show that the density of the elastic-plastic explosive is 1.46g/cm3, the detonation velocity is 6670m/s, the impact sensitivity is 28% and the elastic-plastic explosive can be detonated reliably by a detonator. The explosion hardening on Hadfield steel makes the hardness increased from 187HB to 362HB, which increases by 93.5%.
