The dynamic properties of two types of pressed booster explosives (JH-14C, JHB-1C) and one cast booster explosive PBXN-110 were investigated using Split Hopkinson Pressure Bars (SHPB). The macro and micro failure modes of the recovery specimen were analyzed by high-speed photography and scanning electron microscope(SEM), the corresponding stress-strain curves of three distinct explosives under high strain-rate dynamic response were obtained. Results show that the dynamic mechanical properties of pressed and cast booster explosives are distinctly different and also can be used as reference and guidance for comparison and choice of booster explosives in penetrate warhead designed for over-loading environment.
