Summary
The results from a high-cycle fatigue study on a chemical vapor infiltrated C/SiC composite are presented. Loading frequencies of 4, 40, and 375 Hz were used with a cycle limit as high as 108. A load ratio of 0.05 was used in all cases. The cycles to failure for the composite are presented along with a discussion of the importance of loading frequency. Consistent with earlier work in the literature on older versions of this composite, there does appear to be a dependence upon frequency. However, the characteristic S-N curves have shifted relative to the earlier work. Fracture surfaces have shown fiber damage consistent with fretting fatigue but so far nothing that can be tied specifically to a particular frequency or frequency range. The following paper presents the results of this study and compares them with those of previous authors.
