Abstract: This method permits manufacturing EPDM rocket motor insulation in which carbon fibers are dispersed and immobilized in the EPDM polymeric matrix but are not excessively fractured or fragmentized, i.e., broken into smaller fragments, when encountering degrees of shear necessary to homogeneously or otherwise distribute or disperse the carbon fibers in the EPDM polymeric matrix. The method is substantially solvent free and is performed via distributive/reduced shear mixing to distribute the fragile carbon fibers into a rubber matrix without excessive damage. According to one embodiment, at least about 50% of the elastomer composition introduced into the mixing apparatus is liquid EPDM terpolymer having sufficiently low molecular weight and high diene content to permit dispersion of the carbon fibers in the EPDM without substantial fragmentation of the fibers. According to another embodiment, mixing takes place in a kneader capable of rotating a screw having a discontinuous screw thread about the screw axis while superimposing an axially reciprocating stroke to the screw. The kneader imparts low shear distributive mixing of the carbon fibers in the EPDM terpolymer.

Abstract: Thermoplastic elastomeric ablative insulation having low density are disclosed. The ablative insulation is based upon a thermoplastic elastomeric polymer resin containing a polyamide polymer and a maleic anhydride modified EPDM polymer. The ratio of polyamide polymer to maleic anhydride modified EPDM is in the range from about 20:80 to about 40:60. Carefully selected fillers provide suitable charring and ablative insulation performance without unduly increasing the insulation density. Typical fillers include an phosphorus containing compound, such as ammonium polyphosphate, a polyhydric alcohol present, such as pentaerythritol, silicone resin, chopped fibers, an antioxidant, a butadiene polymer, and a peroxide.

Abstract: A low shear modulus vulcanizate for construction of flexible bearings, particularly for rocket motors, consisting essentially of a mixture of two natural or synthetic rubber copolymers, the first having about 92% cis-1,4-polyisoprene and about 8% trans-1,4-polyisoprene moieties and the second having about 98% by weight cis-1,4-polyisoprene and about 2% by weight trans-1,4-polyisoprene moieties. The composition is lightly filled and contains a low proportion of sulfur, so the vulcanizate has the required low shear modulus, low rate of thermal crystallization at low temperatures, and an acceptably high shear strength.
