Abstract:
1. An insensitive munitions casing for housing a propellant charge comprising: a reinforcing material having a plurality of wound reinforcing layers forming a casing, at least some of said plurality of wound reinforcing layers being cut to define a discontinuous section in the casing; an adhesive bonding material coating said reinforcing material and forming a bond with said casing; a patch covering said discontinuous section and secured to said casing with a patch adhesive bonding material to form a patch bond with said casing; wherein said patch adhesive bonding material has a bond-strength breakdown temperature which is below an auto-ignition temperature of the propellant charge to be housed in said casing such that said patch bond will fail at said bond-strength breakdown temperature causing said casing to separate at said discontinuous section, thereby enabling release of propellant charge pressurization.
