Abstract

Subcommittee C28.07 develops standards for determination of the thermo-mechanical properties and performance of ceramic matrix composites (CMCs) including tension, compression, shear, flexure, cyclic fatigue, creep/creep rupture, ceramic fibers, interfacial properties, thermo-mechanical fatigue, environmental effects, and structural/component testing. Some noteworthy standards developed since the subcommittee’s establishment in 1986 include C1275 “Test Method for Monotonic Tensile Behavior of Continuous Fiber-Reinforced Advanced Ceramics with Solid Rectangular Cross Section at Ambient Temperatures” that has become the basis of other standards involving uniaxial tensile tests. Another noteworthy standard is C1819 “Standard Test Method for Hoop Tensile Strength of Continuous Fiber-Reinforced Advanced Ceramic Composite Tubular Test Specimens at Ambient Temperature Using tlastomeric Inserts” that has direct application to tubular components in the nuclear industry. In addition, several Subcommittee C28.07 standards have been key in the harmonization of international standards in ISO TC206 on Fine Ceramics. Currently, there are seventeen standards under the jurisdiction of Subcommittee C28.07 that undergo periodic review for currency, applicability and technical merit.

Even though current engineering uses of advanced ceramics include such advanced technologies as microprocessor substrates, gas turbine vanes and blades, ball bearings, hip joints, ballistic armor, cutting tools, sensors, and electrolytes [14, 15], prior to 1980 most common engineering uses of ceramics were limited to electrical insulators or wear-resistant surfaces [11-13]. In the mid 1980s advanced ceramics in high-temperature applications such as heat engines, both reciprocating and turbines were of particular interest. During this period, efforts funded by United States Department of Energy (US DOE) in the area of insertion of ceramics in advanced heat engines influenced development of standards for both monolithic advanced ceramics as well as the more damage tolerant ceramic composites.
