Abstract
An insensitive munitions casing, such as a motor case, for housing a propellant charge is disclosed. The casing is formed by winding, wrapping or rolling a fiber, tape or sheet of material such that the casing has a plurality of reinforcing layers. At least some of the reinforcing layers have discontinuous interfaces. Other reinforcing layers may overlap the discontinuous interfaces. The reinforcing layers are coated with adhesive bonding material for adhering the reinforcing layer to itself and bonding the discontinuous interfaces. The adhesive bonding material has a bond-strength breakdown temperature which is below the auto-ignition temperature of the propellant charge. Once the bond strength breakdown temperature of the adhesive is reached, the bond fails at the discontinuous interface, thereby enabling release of propellant charge pressurization.
