ABSTRACT:
A molded explosive member having mating means molded along the periphery to permit interlocking of adjacent members is disclosed. The molded member from an explosive material comprising a mixture of from 30 to 70 wt. % pentaerythritol tetranitrate (PETN) powder, about 1 wt. % graphite, and 70 to 30 wt. % foamable polystyrene beads heated in a closed mold, in the absence of moisture in contact with the PETN powder, graphite, and polystyrene beads, to a temperature of from about 90.degree. to 104.degree. C. to foam the polystyrene beads and mold the explosive material into the desired shape. The amount of PETN powder in the mixture is varied to adjust the desired amount of pressure generated during detonation of the molded explosive member.
