Abstract
A munition is described including a reactive fragment having an energetic material having a least one layer of a reducing metal or metal hydride and at least one layer of a metal oxide dispersed in a binder material. A method is also described including forming a energetic material; including combining the energetic material having a least one layer of a reducing metal or metal hydride and at least one layer of a metal oxide with a polymeric binder material to form a mixture; and shaping the mixture to form a reactive fragment. The munition may be in the form of a warhead, and the reactive fragment may be contained within a casing of the warhead.
Claims26
A munition comprising:
- a reactive fragment comprising an energetic material dispersed in a binder material, the energetic material comprises a thin layered structure, and the thin layered structure comprises at least one layer comprising a reducing metal or metal hydride and at least one layer comprising a metal oxide,
- wherein the thin layered structure is in a form of at least one particle having a size such that the particle will pass through a 25-60 size mesh screen.
A method comprising:
- forming an energetic material comprising a thin film or thin layered structure, the structure comprises at least one layer comprising a reducing metal and at least one layer comprising a metal oxide;
- combining the energetic material with a binder material to form a mixture;
- and
- shaping the mixture to form a reactive fragment,
- wherein the thin film or thin layered structure is in a form of at least one particle having a size such that the particle will pass through a 25-60 size mesh screen.
A munition comprising:
- a casing;
- a plurality of shaped reactive fragments comprising an energetic material dispersed in a binder material, the energetic material comprises a thin layered structure, and the thin layered structure comprises at least one layer comprising a reducing metal or metal hydride and at least one layer comprising a metal oxide;
- and
- a high explosive,
- wherein the reactive fragments and the high explosive are disposed within the casing and wherein the reactive fragments are dispersed throughout the high explosive and wherein the thin layered structure is in a form of at least one particle having a size such that the particle will pass through a 25-60 size mesh screen.
