Abstract:
In the area of ablative applications, progress has been made in carbon roving impregnated with high heat resistant resin. Improvements by superior resin-fiber consolidation achives a tremendous increase in mechanical strength. Experiments with Sil-Temp cordage, as a candidate for ablative winding applications, have been conducted. Two preimpregnated unidirectional tapes have been successfully manufactured thus far. XFT-7067, an epoxy high strength tape, is designed to meet the requirements of Specification OS-10789 for the Polaris program, and XFT-5290, a high temperature phenolic type material, is being evaluated for Lance and other programs. A new process has been developed to impregnate polybenzimidazole resin using a solution coating method. This material is designed for high temperature resistance for prolonged periods. Other work described in this report includes evaluation of new epoxies such as ERLA-0400, new polyesters for preimpregnated roving, and S glass roving with the new 903 finish.
