When we use the X-ray diffraction in order to measure the surface stresses on the material, the X-ray getting into the material deeply may be absorbed to the material. Therefore the intcmal stress can not be measured by this method, and we have to consider the cocfficient of the X-ray absorption. In this study, the Finite Element Metho(FEM) was used to investigate alterations of thermal stress in fiber reinforced metal composite. The microstress distributions of fiber reinforced material were calculated by FEM. The <εφ>-sin^2 φ diagrams considering with the weight average strain of X-ray absorption were estimated for the stress state of the matrix phase and fiber phase respectively. Furthermore the relationship between the surface effects and stress states was discussed from <εφ>-sin^2φ diagrams.
