Abstract: An improved composition for an insulating liner, or insuliner, for a solid propellant rocket motor, which composition comprises a vulcanizable elastomeric composition comprising a vulcanizable elastomer and about 5 to 25 pph (parts by weight per 100 parts by weight of elastomer) of vulcanizing agents for the elastomer, about 10 to 20 pph of aramid polymer fibers, about 5 to 20 pph of a powder filler selected from the group consisting of silica, iron oxide, titanium dioxide, carbon, milled glass and ceramic clays, and about 10 to 25 pph of a bond promoter selected from the group consisting of treated cellulosic fiber and a multifunctional aromatic epoxy resin.

Abstract: The present invention reveals a process for manufacturing a high strength woven fabric that is particularly suitable for use as a tire reinforcement which comprises:(a) drawing a polymeric yarn to a draw ratio that is 70% to 99% of the draw ratio that would fully draw the yarn to produce an optimally drawn yarn;(b) twisting at least two of said optimally drawn polymeric yarns into a cord;(c) weaving a plurality of said cords into a greige woven fabric; and(d) stretching and relaxing said greige woven fabric under conditions sufficient to reduce the denier of the cords in said fabric by 1% to 10%.
