Abstract
An explosive fragmentation structure includes a fragment enhancing insensitive munitions (IM) liner. The IM liner includes a patterned metal structure having openings therethrough embedded in a compressible material to define a desired fragmentation pattern of the outer metal casing upon detonation of the explosive. The IM layer is positioned between and in conformal contact with the outer metal casing's inner surface and the explosive's outer surface.
Claims22
An explosive fragmentation structure, comprising:
- an outer metal casing having an inner surface defining a chamber;
- an explosive positioned inside the chamber, said explosive having an outer surface with a complementary shape to the inner surface of the outer metal casing;
- and
- an insensitive munitions (IM) liner positioned between and in conformal contact with the outer metal casing's inner surface and the explosive's outer surface, said IM liner including a patterned metal structure having openings formed therethrough embedded in a compressible material such that the IM liner is devoid of any air gaps, said IM liner defining a desired fragmentation pattern of the outer metal casing upon detonation of the explosive.

A method of fragmentation enhancement in an explosive fragmentation structure, the method comprising:
- embedding a patterned metal structure having openings formed therethrough in a compressible material to form an insensitive munitions (IM) liner that is devoid of any air gaps;
- and
- positioning the IM liner between and in conformal contact with an outer metal casing's inner surface and an explosive's outer surface.
