%X In order to obtain underwater explosion shockwave characteristics of low energy detonating cord, underwater explosion experiments were carried out in an explosion water tank. The shockwave peak pressure of aluminum composite fiber detonating cord was obtained by using PCB piezoelectric sensor, the shockwave specific energy and the shockwave specific energy in high-pressure zone were calculated. Results indicate that the shockwave energy output of aluminum composite fiber detonating cord is mainly concentereted in the high-pressure zone within characteristic time and accounts for 84% of the total shockwave specific energy volume. Above results may lay a sound foundation for its future promotion and application.
