ABSTRACT:
In the inventive shaped charge, the main charge and the propagating charge are held together solely by the barrier. This union is possible (and is distinguished by pronounced freedom from flaws) because the barrier is produced directly in the cavity in which it is to remain and is able to conform with the utmost accuracy to the surfaces of the charges. The barrier is advantageously formed under vacuum. Factors to be considered in the selection of the barrier material are its fluidifiability, its solidification and shrinkage behavior, and its compatibility with the explosive. Suitable barrier materials include single- or two-component foams, casting compounds, resins and adhesives.
