Physical challenges and limitations confronting the use of UHTCs on hypersonic vehicles. Glass, D., E.

Paper doi abstract bibtex Ultra-high temperature ceramics (UHTCs) have been studied for many years as possible material solutions for leading edges of hypersonic vehicles. Over that time, many of the processing and engineering challenges have been addressed. Though UHTCs may have high-temperature capability for some applications, there still remain several physical challenges and limitations confronting their use on hypersonic vehicles. UHTCs possess a very high density, and for weight sensitive vehicles, high density can lead to significant weight concerns. Being monolithic ceramics, UHTCs have thermal shock and fracture toughness concerns that confront all non-fiber-reinforced ceramics. The limitation discussed here for UHTCs is high-temperature oxidation in flight environments. In the temperature range of ~2900°F (~1600°C) and below, Si-based UHTCs form a protective silica (SiO2) layer that helps protect the substrate from oxidation. Above that temperature range, Si-based UHTCs appear to experience similar active oxidation issues that confront structural ceramic matrix composites (CMC) such as C/SiC and coated C/C. Non-Si-based materials should be considered to realize a true step forward in temperature capability with respect to conventional Si-based CMCs.
