OS04W0169 Study of residual stress for c/c composite by neutron scattering

Abstract

The aim of the present paper is to clarify the residual stress occurring in the c/c composite to improve the manufacturing process. The residual stress was measured by a neutron diffraction method using the RESA in the JRR-3M of JAERI in this study. As a results of the residual stress measurement, it was found that the residual stress of the ring type c/c composite is the compressive stress, and that the macroscopic residual strain/stress is absorbed mainly microstructural change such as pore shape change.
