ABSTRACT:
A layer of high temperature resistant polymer material such as polysulfone r polyimide is bonded between the liner and energetic material in a solid fuel rocket motor, warhead, or other ordnance item. This layer prevents or delays ignition of the energetic material when the ordnance item is exposed to a high temperature environment. The layer does this by forming an impervious barrier between oxygen trapped or chemically contained within the energetic material, and gaseous fuel resulting from chemical degradation of the liner. Combustion of this gaseous fuel and resulting ignition of the energetic material is thus avoided or delayed.
