Description
It is critical to the safe use of ceramic matrix composite components that information on the fracture toughness of these materials be available, in order to allow an assessment of the likelihood for crack growth. Although Military Standards and American Society for Testing and Materials both serve as resources for room and elevated temperature test methods, there are no standards to obtain the interlaminar fracture toughness in CMCs. This proposal seeks to develop a reliable process for measuring the Mode I and Mode II fracture toughness at any temperature for CMC materials. The process includes the selection of the best test method, the specification of the test procedures, the design of the test specimen, and the determination of the fracture toughness from the measured data.
