Japan Atomic Energy Research Institute (JAERI) is planing to use a C/C composite for a tube of nuclear control in the High Temperature engineering Test Reactor (HTTR). The C/C composite is required excellent high strength at high temperature and excellent nuclear characteristic. The tube of nuclear control rod in the reactor received the self weight and the earthquake load to the axial direction, and the nuclear heat stresses to the circumferential direction. Therefore, it is important to establish the fracture criterion of the C/C composite under multi-axial stresses. In this study, we evaluated the tensile-internal pressure, the compressive-internal pressure strengths of the C/C composite to make clear the fracture behavior under multi-axial stresses. The inside stresses of the C/C compsite also analyzed by FEM considering inhomogeneous unisotropic body.
