What Is a Ceramic Matrix Composite?
A Ceramic Matrix Composite (CMC) is a type of composite material that combines a ceramic matrix with reinforcing materials like ceramic or metal fibers.
CMCs integrate the attributes of ceramics, such as heat resistance, oxidation resistance, and wear resistance, with the strength and stiffness of reinforcing materials. This unique blend has propelled CMCs to the forefront as promising next-generation structural materials.
The applications of CMCs span various industries. In aerospace, they’re utilized in turbine blades for aircraft engines, rocket nozzles, and heat-resistant spacecraft components. The automotive industry employs CMCs in brake rotors, exhaust systems, and catalytic converters. In the energy sector, CMCs are crucial in nuclear reactor fuel rods and battery electrodes.
