Ceramic Matrix Composites: Performance
Hot-Fire Test at 4350ºF (2399ºC)
Melt-infiltrated CMC lined carbon/carbon leading edge before
and during arcjet test at NASA Ames Research Center
Melt-infiltrated Cf/ZrC combustion chamber survived multiple 30-second
oxygen/hydrogen hot-fire tests to 4350ºF at NASA Glenn Research Center
Laser Test Up to 5200ºF (2871ºC)
Melt infiltrated Cf/ZrC and Cf/Zr-Si-C composite panels were tested at the Air Force LHMEL-I facility using laser heating and Mach 0.7 airflow.
Weight change was minimal following tests up to 5200F for 300 seconds.
