Research Abstract

In the current research, (1) unidirectional advanced SiC/SiC model composites (minicomposites) were fabricated with smaller and nearly same cross-section and with relatively low cost, for neutron irradiation study on SiC/SiC composites in near-term future. (2) The effects of fiber surface roughness and interphase thickness of the minicomposites on tensile and interfacial properties were examined by unloading-reloading cyclic tensile tests, the hysteresis loop analysis, and single fiber push-out test. Additionally, (3) an evaluation method was suggested for microstructural change of pyrolytic carbon interphase before/after irradiation by an image analysis using TEM micrographs.
