This Phase I SBIR program seeks a new fabrication method to produce stronger and tougher ultra-high temperature ceramic (UHTC) composites with an outstanding oxidation and thermal shock resistance for use as components for tactical propulsion applications. UES will apply a novel "Hybrid-Clad" approach to achieve lightweight composites, along with the "Top Down" process to control the microstructures of the composites. This approach will produce a very unique grain structure that can offer high strength, high fracture toughness, and high oxidation resistance. Spark plasma sintering or hot isostatic pressing will be used as a means for densification during the Phase I study. During the Phase I program, UES will collaborate with MR&D to conduct thermal-structure analysis in order to compute transient temperatures, deformations, stresses and strains for the materials within the selected propulsion system component during simulated operation.
