A facile pressing technique for the preparation of small calibre dual role explosive charge

Small calibre shaped charges are prepared by the pressing method. The shaped charge performance is considerably influenced by the density gradient which is an inherent drawback associated with the pressing method. A new method, double action pressing technique has been developed which overcomes this problem and is amenable for large scale production. Properties of the charges prepared by the different methods especially with respect to the den sity gradient and performance against targets are presented and discussed.
