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.

A method of assembling a shaped charge in a mold, comprising: fixing separately produced main and propagating charges together leaving a cavity formed by the main charge and by the propagating charge, filling that cavity with a solidifying material while said solidifying material is still in the fluid state, and allowing said material to solidify with temperature-independent shrinkage behavior to form a barrier in the cavity by curing or polymerizing and thereby bonding that material tenaciously to the main charge and the propagating charge.
