ABSTRACT: This Phase II SBIR program involves a novel process to produce new hybrid ultra-high temperature (UHTC) ceramic composites that can survive hypersonic flight conditions. The new process will produce a very unique grain and graded microstructure that can offer high strength (> 100 kpsi), high fracture toughness (> 10 MPam), high thermal shock resistance, and high oxidation resistance over 2000oC. Thus, the new hybrid composites can serve as leading edges for hypersonic applications. Spark plasma sintering or hot-pressing will be used as a means for densification. In addition, near-net shape fabrication will be explored to produce sharp leading edges during the Phase II program.; BENEFIT: The successful completion of the Phase II program will provide the foundation needed to produce oxidation and thermal shock resistant UHTCs. Examples of primary applications are leading edges for hypersonic vehicles, as well as solid rocket motors (SRM) for various DoD applications including all rocket nozzles, and other ground-based missile interceptors.
