Summary

The influence of test specimen size on the fracture behavior of C/C and SiC/SiC composite materials was investigated. The fracture tests with unloading-reloading sequences were conducted by using compact tension test specimens with different thicknesses and widths. In situ observations of fracture process were conducted by video microscopy and the fracture surfaces were examined by scanning electron microscopy (SEM). Based on the correlation between the size of test specimens and R-curve behavior, the applicability of small test specimens for the fracture resistance determination in ceramic matrix composites (CMCs) was investigated.
