    Abstract
  • In order to study the explosion properties of the aluminum foil explosive, a high-content aluminum foil explosive, obtained by mixing aluminum foil with RDX uniformly, was chosen and compared with aluminum powder explosive in underwater explosion.The difference of the major parameters, such as the peak pressure, the impulse, the specific shock wave energy, the specific bubble energy, and the specific explosion energy, were obtained by analyzing the pressure vs.time curves recorded at different distances.The results from this experiment suggest that the decay rate of the peak pressure of the aluminum foil explosive is slower than that of the aluminum powder explosive, and the impulse and specific shock wave energy from the two explosives nearly match each other.The specific bubble energy of the aluminum foil explosive is slightly greater than that of the aluminum particle explosive due to its smaller specific surface area with high purity of aluminum and the longer bubble pulsation period of the aluminum foil explosive, so that the total energy of the aluminum foil explosive is slightly greater than that of the aluminum powder explosive.
