Fiber reinforced ceramics with high composite translational efficiency will be significantly stronger, tougher, higher in bull, more creep resistant, and more resistant to thermal shock and cycling than monolithic ceramics. Pat. Pend. Sullivan fiber coatings will provide efficient composite translation. Rt. strengths 716 mpa to 1246 mpa and 1000 deg C strengths of 542 mpa to 1200 mpa are anticipated. Thermal shock parameter of the matrix will increase 320%.
