The carbon fiber reinforced silicon carbide matrix (C/SiC) composites were prepared by using precursor infiltration and pyrolysis method. Fracture characteristics of C/SiC materials were studied by single edge notched beam with the aid of digital image correlation (DIC) technique. It was found that DIC played an important role inin-situmonitoring full/local strain evolution and cracking growth during bending tests, which was useful for revealing potential failure micro-mechanisms of C/SiC composites. The results showed that the average fracture toughnessKICand fracture strength of C/SiC were estimated as 7.81±0.12 MPa m1/2and 223.23±3.5 MPa, respectively. Moreover, the crack extension resistance curves (R-curve) in terms of stress intensity (KR-curves) were determined on the basis of the crack initiation toughnessKIC. The values varied from 4.68 MPa m1/2to 16.83 MPa m1/2during the R-curve tests.
