摘要：
SiC/SiC composites, with unidirectional low oxygen fibers and with unidirectional low oxygen and highly crystalline fibers were fabricated by chemical vapor infiltration method and irradiated at Japan Material Testing Reactor and High Flux Isotope Reactor. The effects of neutron irradiation on mechanical properties were evaluated by three point flexural tests. Microstructure and fracture behavior were observed by scanning electron microscopy prior to and after neutron irradiation. The SiC/SiC composites with a low oxygen content, near-stoichiometric and highly crystalline SiC fibers showed the excellent stability to the neutron irradiation. The mechanical performance of this material did not degrade, even following the neutron irradiation of 10 dpa, while the other materials with the other fibers degraded significantly.
