Abstract
A polymer adhesive includes a polymeric binder, optional reinforcing fibers dispersed through the polymer binder and solids dispersed in the polymeric binder. The solids are effective to cause decomposition of the polymer adhesive at a temperature between 200° F. and 500° F. with a generation of gaseous products at a predetermined temperature. One suitable composition includes siloxirane, graphite, glass beads, potassium nitrate, silver nitrate and lactose and decomposes at a temperature of about 318° F. The polymer adhesive may be used in the assembly of a housing for rocket motor or a warhead. Decomposition of the polymer adhesive when the housing is exposed to sufficient external heat to cause a rocket propellant or warhead explosive to decompose, referred to as cook-off, enables venting of the rocket propellant or warhead without uncontrolled destructive rupture of the housing.
