Abstract
The application discloses and claims an oxidation resistant, continuous-fiber-reinforced ceramic composition, durable at temperatures above 1000° C., and capable of taking on any arbitrary near net shape formed without machining and tooling. The composition of the invention comprises a fine grained ceramic matrix which in turn comprises a mixture of a ZrBphase and a SiC phase with the matrix being reinforced with SiC or C or an oxide fiber, resulting in a fine grained ZrB—SiC matrix with domain sizes ≦0.5 μm. The ZrBphase of the invention is capable of forming small microcrystalline domains ≦0.5 μm upon heat treatment. The composition the invention also comprises a fiber reinforced composite with a high degree of filling and densification of its preform resulting in a composition containing a low level of porosity and high fiber volume fraction.
