Ceramic Matrix Composites

Material Systems

  • Cf/ZrC—oxidizing environments of >3500°F (1940°C)

  • Cf/HfC—oxidizing environments of >4000°F (2200°C)

  • Cf/SiC-ZrC and Cf/SiC-HfC—oxidizing environments up to 4000°F (2200°C)

  • CMC-encased or CMC-lined carbon/carbon structure

  • Cf/TaC and Cf/TaC-HfC
