This paper describes the neutron irradiation effects on dimensional change and thermal expansion rates for heat resistant ceramics, a carbon/carbon composite and SiC/SiC composite materials promising for nuclear engineering application. A series of irradiation tests was performed using the Japan Materials Testing Reactor (JMTR) with irradiation temperatures from 573 to 1173 K at fast neutron fluences from 1.8×10^<24> to 1.1×10^<25> m^<-2> (E>1MeV). In the post-irradiation examinations, measurements were made on (1)dimensional changes and (2)thermal expansions. Obtained results for the C/C and SiC/SiC composites were compared with other data in existing literatures in this paper.
