  The study of interfacial properties is of significance to the development of fiber reinforced composite.In this paper a theoretical analysis for the single-fiber pullout with unloads and reloading process is presented based on theshear stress debonding criterion and the modified analysis of stress.The influence of key parameters includes radial residual thermal stress the volume content on the relationship between the applied stress and the interfacial relative displacement is presented based on the shear stress debonding criterion during the unloading process.The applied-interfacial relative displacement is presented during the reloading process.The calculation results show that the applied stress to cause further debonding increases with the increase of the radial residual thermal stress and the fiber volume content during the unloading process.The applied stress to reduce reverse sliding increases with the increase of the radial residual thermal stress and the fiber volume content during the reloading process.
