Study of polysulfonamide pulp in silicone rubber insulation composites
Silicone rubber insulation for a solid rocket motor was fabricated by adding pretreated polysulfonamide (PSA) pulp. The effect of varying the content of PSA pulp in the silicone rubber on its dispersion was analyzed, as well as the effect on the tensile strength, elongation at break, ablation rate and hardness of the resulting composite. The results showed that pretreatment of the PSA pulp enhanced both its dispersion in the silicone rubber and the interfacial bonding between the pulp and silicone matrix. When the content of PSA pulp was no more than 15 parts per hundred silicone rubber the tensile strength of the material showed an increase, and the elongation showed a decrease, with increasing content of PSA pulp. The erosion resistance increased with increasing content of PSA pulp. The silicone insulation with PSA pulp as a filler has potential applications in solid rockets or ramjet rockets.
