About this technology

Overview

Innovators at NASA's Glenn Research Center have conducted leading-edge research toward the development of silicon carbide (SiC) fibers and SiC/SiC ceramic matrix composites (CMCs) that can be used in high-temperature structural applications, such as hot components in gas turbine engines. Glenn has gained recognition for the innovative design and processing technologies required for these materials. NASA's patented SiC/SiC CMC technologies use the advantages of non-oxide SiC fibers and matrices to yield ceramic composites that can withstand adverse structural and environmental conditions for long times at temperatures up to 2700°F. The CMC properties offer significant benefits in comparison to other options, including metallic superalloys, monolithic ceramics, carbon fiber composites, and oxide/oxide ceramic composites. These composites are also invaluable in their ability to be engineered for specific stress, temperature, life, and environmental conditions.
