The subject invention relates to a coated reinforcement material comprising a SiC reinforcement having a coating of at least three layers, wherein the layers are alternately A-material layers of the general formula: AlxOyNz wherein x is up to about 60 atomic% of the coating; y is from about 15 atomic% to about 55 atomic% of the coating; and z is from about 5 atomic% to about 45 atomic% of the coating, with the proviso that x+y+z-100, and B-material layers comprising a metal alloy, such that the first and last layers of the coating are A-material layers. The invention further relates to a high stength, high temperature performance composite containing the above-specified coated reinforcement. |
