Effect of interfacial properties in fiber-reinforced ceramic matrix composites is critical to overall mechanical behavior of the composite. In this study, the surfaces of several ceramic fibers (Nicalon SiC, Nextel aluminosilicate) were studied qualitatively using a FEG SEM at low voltages and quantitatively using AFM. Nicalon fibers had a Ra (arithmetic mean of absolute values of departure of roughness profile from mean line) of 3.4 nm over several line scans, 3.9 nm from area analysis. Nextel fibers, which are oval, are slightly rougher than Nicalon and have an average Ra of 4.8 nm from several line profiles. Grooves ran the entire length of the Nextel fibers. 5 figs, 5 refs.
