Abstract

The R-curve behavior of SiC whisker / Al2O3 matrix composites was evaluated. Composites were fabricated with Silar SC-9 and Tateho SCW-1-S SiC whiskers. The properties of the two SiC whiskers were similar in all aspects, except for significant differences in surface chemistry. These differences were found to be a key factor in determining the R-curve behavior
