  • Aluminum fiber explosive containing explosive and aluminum fiber which is made from pure aluminum is a novel non-ideal explosive.Pressure-time curves of aluminium fiber explosive at different positions were measured by underwater explosion experiments.The peak pressure, impulse, shock wave energy and bubble energy were obtained by analyzing the pressure-time curves.Pressure-time curves can be described by exponential and hyperbolic function at distinct stages.The fitting effect of bubble oscillation curve using normal distribution function is not ideal.That specific bubble energy is 52%-58% of the explosion energy, which shows the effect of adding fiber.The explosive energy declines to 75%-85% of the explosion heat because of the imperfect reaction and crushing energy cost of Al fiber.
