Abstract
As a result of concerns about restrictions on the industrial use of asbestos, DREV initiated a research project aimed at replacing asbestos in the rocket motor insulant designated RF/B. RF/B is a polymer composite consisting of a carboxyl-terminated polybutadiene filled with asbestos. While retaining the same polymeric resin, a combination of fibers (Kevlar, Refrasil and Pyron) and fillers (kaolin and Mg(OH)2) was used to obtain formulations compatible with the processing of RF/B, which is based on the use of a sigma-blade mixer and two-roll mills. The mechanical properties of the new material and its suitability in CRV7 rocket motors were assessed.
