Effect of Neutron Irradiation on the Dimension and the Strength of Carbon Fiber/Carbon Composite Derived from Thermosetting Resin Precursor

概要

論文の詳細を見る
Unidirectionally reinforced carbon fiber/carbon composite whose matrix was derived from thermosetting resin, was prepared. The heat-treatment temperature was 2800°C. The change in size and 4 point bending strength of the composite was measured after neutron irradiation (640°C, 6×1024n/m2, E>1MeV). Shrinkage in normal to the fiber direction was larger than that in fiber direction. Increase in strength and Young's modulus of the composite was observed after irradiation. Irradiated composite showed much higher deflection to fracture than unirradiated one.
