Abstract

A high strength structure is formed of an inner layer of one material fibers and an interbraided outer layer of second material fibers so that there is a hybrid dual fiber interface or zone, and the layers are then separately sequentially densified with compositions by chemical vapor deposition to provide a tailored, highly oxidative resistant interior with a high strength exterior. The inner fibers may be silicon carbide while the outer fibers are graphite, and the inner densification compositions are carbides, nitrides and carbon, with the outer densification compositions being silicon carbide or graphite. The structure is useful for combustion chambers, engine components and high pressure corrosive chemical vessels.
