Competitive, national security, and efficiency concerns provide an urgent need for ceramic matrix composite research and development, particularly for use in hypersonic and turbine engine applications. Thermal and mechanically-induced stresses in these structures limit speed, strength, and life-expectancy. Composite performance may be greatly enhanced through the use of novel additives, such as fibers, nano-particles, or interphase coatings and may enable a much broader use of composites in the aerospace industry. Offeror proposes a 6-month Base and 6-month Option project for the development of fabrication methods and the application of novel additives to ceramic matrix composite fibers. Fiber fabrication will be followed by testing and modeling for oxidation and creep resistance of the fibers (both with and without additives) for function at temperatures up to 2000°C. Project data will be compiled into detailed databases for future use in design and manufacturing of complex ceramic matrix composite components for DOD-related technologies and future commercial applications.
