摘要：

A study has been conducted of the effects of neutron irradiation on dimensions and mechanical properties of a carbon fiber/carbon composite. The matrix was derived from a thermosetting resin and the reinforcement was a PAN-based carbon fiber. Irradiatio up to 4.5 x 10(24) n/m2 at 240-degrees-C gave rise to shrinkage parallel to the fibers and expansion perpendicular to them, while irradiation to 6.0 x 10(24) n/m2 at 640-degrees-C produced the opposite (i.e., parallel expansion and perpendicular shrinkage). The mechanical strength, failure strain and fracture energy increased after neutron irradiation, while Poisson's ratio decreased to about one half the value before irradiation. These effects are correlated to structural changes in the matrix and/or interface induced by the irradiation.
