Hybrid reinforcements for high temperature composites and composites made therefrom.

摘要

The subject invention relates to a hybrid reinforcement material comprising a refractory metal core having a first coating comprising aluminum, oxygen and nitrogen, this coating of the general formula: AlxOyNz wherein x is up to about 60 atomic% of the coating; y is from about 20 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 having a second SiC coating. The subject invention further relates to a high strength, high temperature performance composite containing the hybrid reinforcement specified above.
