Due to the nature of hypersonic flow, it is difficult for many materials to withstand the extreme conditions at these speeds. Even UHTCs, a material used in hypersonic craft for its high thermal stability and strength, still present many problems, including brittleness and a lack of reusability. Solving these issues will allow hypersonic crafts to be closer to commercial viability and long term use. Our research aims to determine how we can improve the strength of UHTCs by 10% through Silicon Carbide fibers, microcracking, and other means. This is a goal within reason, but also provides enough of a benefit to be useful.
