This paper describes the evaluation of thermal deformation of the CFRP-aluminum fastening structure using stereo DIC (stereo digital image correlation). This structure is used at the FOB (Fixed Optical Bench) of the astronomical satellite “ASTRO-H.” The fastening structure is heated up with a self-made thermostat, and the in-plane displacements on the three-dimensional surface of it are measured using stereo DIC. Then, the strains are evaluated and the results are compared with those obtained by FEM. By comparing experimental results with those of finite element analysis, the finite element model is improved, then analysis of thermal deformation of the fastening structure is made more accurate and easily.
