components

UHTCMCs enable aerospace components to operate reliably in extreme thermal and oxidative environments. Their density combined with high-temperature strength helps reduce dimensions and mass while sustaining performance at temperatures where other composites and superalloys struggle. Potential applications include thermal protection hardware, nozzles for hybrid and solid propulsion, leading edges, and hypersonic vehicle components. The material’s thermal stability can support tighter thermal margins, longer service life, and improved mission capability.
For next-generation propulsion and re-entry platforms, UHTCMCs can be a pathway to higher operating temperatures and improved efficiency.
