Ceramic Composites Survive Severe Thermal Shocks

Ceramic-composite turbine blades and other components that must withstand severe thermal shocks developed for aerospace and, potentially, for terrestrial applications. Made of silicon carbide reinforced by continuous carbon fibers. Materials withstand high temperatures, exhibit high toughness, and fail gradually. Commercial applications include brake linings for fast trains and aircraft, industrial heat exchangers, and nozzles and other devices for handling molten metals.
