In this study, PAN-based carbon fibers impregnated with phenolic resins used a precursors of carbonized matrix was modified by addition of Al2O3. The content of Al2O3 was varied in 0, 1, 5 and 10 wt% on the basis of resin matrix. These composites were unidirectionally manufactured by prepreg method, and were submitted to carbonization (heat treated to 1100°C). The mechanical interfacial properties of the composites were studied in interlaminar shear strength (ILSS) and critical stress intensity factor (KIC) of the composites measured at High Temperature |
