ABSTRACT:
An organometallic polymeric resin is used to impregnate glass filaments (or oron, graphite, carbon, etc.) which are employed in the fabrication of composite motor cases and inert components of a solid propulsion system. The resulting motor case or inert component has the ability of regulating the amount of damage that a nuclear blast would inflict on the solid propulsion system to a level which is below the threshold damage value and the system remains operable. The metal of the organometallic polymeric resin is integral with the resin molecule. The preferred metal is tin which is effective in imparting an ability to stop or slow the passage of photon energy because of its capacity to absorb such energy. Representative of the organometallic polymer is an organotin-containing acrylate polymer which is capable of undergoing polymerization into transparent, easily-formed, mechanically-strong, heat-stable glasses which are capable of stopping, or retarding the rate and amount of penetration of radiation from nuclear blasts. The boron, graphite, and carbon can be used as an additive to the composite motor case ingredients, or can be used along with glass fibers, or can be used separately as the major constituent of an inert motor component such as throat insert, nozzle, conical transition section, nozzle expansion cone, heat shield, insulation, and liner material.
