Abstract:
Provided is an insulation for rocket motors that uses two ingredients not previously combined in such insulation before. These ingredients are ammonium sulfate and antimony oxide, which when combined, have a synergistic effect that reduces the ablation rate significantly. Such insulation also includes EPDM rubber and aramid fibers. The inventive insulation also exhibits better tear resistance and propellant-to-insulation bond peel strength, compared with prior art rocket motor insulation.
