Development of Novel Hybrid UHTC Composites for Advanced Tactical Propulsion Systems (16-RD-882)

This Phase II SBIR program will develop a technical foundation for commercialization to realize stronger and tougher ultra-high temperature ceramic (UHTC) composite clads with an outstanding oxidation and thermal shock resistance for use as key components for tactical propulsion applications. UES will apply a novel cladding approach to achieve lightweight UHTC components along with the "Top-Down" process. This approach will produce an exotic grain structure that can offer high strength, high fracture toughness, and high oxidation resistance. Spark plasma sintering (SPS) or hot isostatic pressing (HIP) will be used as a means for producing dense clad layers. During the Phase II program, UES will continue to refine the Hybrid-Clad approach in order to obtain the desired material performances. In addition, UES will collaborate with Plus Designs and Orbital ATK to conduct thermal-structure analysis as well as hot firing test. Approved for Public Release | 16-MDA-8951 (15 December 16)
