Abstract
A fragmentation casing for shells, warheads and the like, in which pre-shaped fragmentations or splinters of hard or hardenable material are embedded in a supporting structure which is formed by a material that surrounds the fragmentations on all sides. This material is adapted in response to the ignition of an explosive charge provided in the fragmentation casing to disintegrate into individual particles to thereby release the pre-shaped fragmentations or splinters. The fragmentation casing includes a shell base body which within the region of a sleeve-shaped portion intermediate the rear portion and the head portion of the shell base body is provided with an outer recess which is cylindrical at least over a portion of the shell. Placed in this recess as a single layer are pre-formed fragmentations, primarily heavy metal balls, together with a material which is hardenable by sintering. These fragmentations placed in the recess are pressed into a supporting structure surrounding the fragmentations. The fragmentations are pressed into and sintered in a sleeve-shaped fragmentation mantle.
