Ceramic Matrix Composites I: Materials and Manufacturing

Ceramic matrix composites are key enabling technologies to meeting the demand of fuel-efficient gas turbine engines.  They offer low density, high strength and toughness, and improved high temperature stability relative to nickel-based superalloys.  During the past decades, new continuous ceramic fibers and innovative manufacturing methods for ceramic matrix composites have been developed.  The scientific fundamentals for designing and tough and durable CMCs have also been realized.  For example, Composite Horizons (Covina, CA) has begun manufacturing CMC mixer and center body assemblies for aircraft engines.  However, significant technical challenges remain in CMCs in designing a complex microstructure to improve performance and durability. In this short course, recent advances in processing, structure, properties and performance of various oxide- and carbide-based CMCs will be discussed.
