TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Glacigen Materials proposes a novel technique for producing large-area sheets of functionally graded materials (FGM), which yield robust ceramic-metal interfaces capable of withstanding harsh environments that include high temperatures. Propulsion systems offer some of the harshest possible design conditions from a materials perspective and the demands placed on engineering materials will become more rigorous in future systems. The combination of structural and environmental constraints often dictate that ceramics and metals be used synergistically. Unfortunately, the limitations of ceramic-metal joining are exacerbated in these same environments where simultaneous use of ceramics and metals would be most useful. Large discrepancies in thermal expansion coefficients and near-planar interfaces lead to delamination and spallation even in the best engineered bonds.
As a novel approach to this problem, Glacigen will create robust C-M interfaces by grading from one material phase to the other through a tailorable thickness. The technique is materials flexible, enjoys exceptional damage tolerance, and can accept significant mismatches in thermal expansion coefficients. The method for producing FGM sheets presented in this proposal will have the added advantage of controlled anisotropic properties within the sheets. In particular, it is anticipated that this new material system will be particularly valued for its damage tolerance at the interface where up to 96% of the interface can be destroyed before contact area is reduced to that of a planar joint with the same footprint. A second point of unique value will lie in the utility of engineered anisotropy where through thickness thermal conductivity is expected to be dramatically higher than in-plane thermal conductivity. Phase I efforts will demonstrate fabrication of these sheets and will include the characterization of mechanical, thermal, and functional properties.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Specific applications which are foreseen at this time include hybrid electric propulsion systems, damage-tolerant radiators, and gas turbine components. The fundamental technology also has the potential to extend into high-temperature aerostructures. As efforts continue in the development of hypersonic vehicles, extreme environmental conditions dictate the need for better ceramic-metal interfaces along the leading edges of these structures.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
NASA applications in hybrid electric propulsion systems, gas turbine components, and thermal management systems can be directly applied similar or identical problems of commercial interest.
