Abstract
An improved process of making shaped explosives for a shaped charge device. n the process, the crystalline explosive is divided into two parts. One part of the explosive is coated with a liquid prepolymer, and the second part is coated with a liquid curing agent. The two parts are combined, shaped, and consolidated at room temperature under a pressure of 20000 psi for a dwell time of one minute to produce a shaped explosive.
