الوصف: The flexibilization of epoxy, melamine, phenolic, urethane, and furan resins for use as thermal insulation binders in end-burning, solid-propellant rocket motors is described. The effect of aging on the mechanical properties of two externally plasticized epoxy resins was determined. For several resins, asbestos fibers, potassium oxalate, and magnesium carbonate fillers were evaluated in the oxyacetylene-torch test and static-motor firings. The char rates (from motor firings) and densities for the motor promising systems were: 3.0 mil/sec, 1.41 gm/cu cm for an asbestos-filled Epon 328-Nadic methyl anhydride-castor oil formulation; 2.4 mil/sec, 1.52 gm/cu cm for an asbestos- filled Araldite DP-437 NMA formulation; 2.7 mil/sec, 1.37 gm/cu cm for an asbestos-filled nonyl phenol-formaldehyde-Syl-Kem 90 formulation and 2.1 mil/sec, 1.50 gm/cu cm for asbestos-oxalate-filled phenolformaldehyde-Syl-Kem 90 formulation.
