Two broad categories of applications of CMCs (ceramic matrix composites) are aerospace and non-aerospace. In the former, performance is the foremost consideration while in the latter cost effectiveness is the prime consideration. Continuous fiber reinforced ceramic composites potentially offer higher specific mechanical properties which can be utilized in a variety of high-temperature applications. Carbon/carbon composites are used as a thermal protection material in the US space shuttle and in aircraft brakes. Carbon fiber/silicon carbide composites are candidate materials for many space plane programs. Besides the space plane, other applications for ceramic matrix composites include a US program called high speed civil transport (HSCT), various defense related projects such as advanced tactical fighter (ATF), many existing fighters, missiles, hypersonic radomes, hard armor and turbine engines. It is expected that a number of propulsion related components in HSCT will use a variety of CMCs. Examples of the non-aerospace, high temperature applications of CMCs include engine components at high temperatures and in corrosive environments, cutting tool inserts, wear resistant parts, nozzles and exhaust ducts, energy related applications such as heat-exchanger tubes, high temperature filters etc. are the prime areas. For such applications, the components can range from simple to complex and tend to be smaller in size. Dense, wear-resistant, particle- and whisker-reinforced CMCs are being used in such applications.
