ABSTRACT:
A fiber reinforced composite tape is made by casting a mixture comprising high temperature metal or intermetallic particles, substantially continuous ceramic fibers and a polymeric binder. The particles are preferably titanium alloy or titanium aluminide particles having a top size of greater than about 50 microns and the binder is preferably a polyisobutylene. The cast composite tape is combined with other tapes, heated in a vacuum to remove the binder and pressed at an elevated temperature and pressure to form a composite structure suitable for high temperature applications.
