CFCC components allow increased temperatures resulting in substantial reductions in nitrous oxide (NOx) emissions and savings in the cost of power generation [2] Thermo-mechanicat behavior (and its subsequent characterization) of CFCCs is currently the subject of extensive investigation worldwide [3-5] In particular, determination of the properties and performance (mechanical, thermal, thermomechanical,... standards writing body for formal normalization The American Society of Testing and Materials (ASTM), the European Committee for Standardization (CEN), NASA's EPM program, the International Standards Organization (ISO), and others have developed, or are developing new standards for CMCs (Table 1), and monolithic advanced ceramics It is important that test standards development continue because standards:... protection of life and property for a reasonably-long safe-life of the design Although needs of the users, manufacturers and inspectors are recognized, the safety of the design can never be compromised A logical outcome of design codes is the incorporation of data bases of material properties and performance 'qualified' for inclusion in the code 'Qualified' means that the data have been attained through testing. .. Based on the needs of existing standards and the needs of evolving design codes/data bases for CFCCs Several goals were set forth for this study: 1) to develop precision and bias statements for each Of three national standards for CFCCs (required by ASTM), 2) to contribute to an expanded, reliable data base for CFCCs, 3) to provide statistical distributions of properties and performance of a single CFCC... test configuration and a photograph of the test setup at one of the laboratories are shown in Fig 5 The primary mechanical property of interest was the interlaminar shear strength a) Schematic of the interlaminar shear test b) Example of an interlaminar shear test Figure 5 - Illustrations of interlaminar shear test setup per C 1292 22 CERAMIC COMPOSITESAND COMPONENTS a) Schematic of the in-plane tensile . publication, Mechanical, Thermal and Environmental Testing and Performance of Ceramic Composites and Components, contains papers presented at the Symposium on Environmental, Mechanical, and Thermal.
