DEVELOPMENT AND EVALUATION OF IMPROVED RESINS FOR FILAMENT WOUND PLASTICS.
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.
