As aerospace engineers attempt to create products that can fly faster, higher and more efficiently, new types of materials are essential. Ceramic matrix composites (CMCs) hold tremendous promise. However, they can be difficult to join.
CMCs are made of coated ceramic fibers surrounded by a ceramic matrix. They are tough, lightweight and capable of withstanding temperatures 300 to 400 F hotter than metal alloys can endure. Because of those qualities, they are ideal for jet engine applications.
