Summary

Commercialization of advanced ceramic composites requires standardization of test methods and data bases both for bench marking processing improvements and for use as input for the design of components. National and international standardized test methods for CFCCs have been increasingly introduced over the past decade. Widely-available data bases are just now being developed. Three ASTM test methods (C1341 for flexure, C1275 for tension and C1292 for shear) were used to evaluate of a commercial CFCC (ceramic grade Nicalon™ fabric-reinforced silicon nitrocarbide matrix). Nuances of the test methods were investigated through the use of rosette strain gages, dual data acquisition systems, multiple parameter measurements and other experimental techniques. Quantities such as off-axis strains, non-uniform stresses, differences in displacement measurement techniques, and variability in dimensional determination were used to interpret differences between inter and intralaboratory results.
