Ceramic Matrix Composite （CMC）， knowns for its exceptional resistance to high temperatures， low density， high specific stiffness， and high specific strength， has emerged as a crucial structural material in the aerospace industry， and is increasingly being utilized in aerospace thermal structural components. Therefore， the design of connecting structures and the performance assessment of CMC and metal parts are pivotal in enabling the widespread application of CMC. To study the high-temperature springback properties of the CMC-metal flexible support structure， a test simulator of the CMC-metal flexible support structure was designed according to the typical characteristics of the support structure， and compression fatigue tests were carried out under high-temperature conditions. The fatigue deformation behavior of the support structure and the springback properties of the metal spring plate specimen were observed and quantitatively analyzed in-situ online using the DIC method. The results show that the springback ratios of the inner and outer support metal spring plate specimens are affected by the cyclic hardening and the accumulation of inelastic deformation of the structure. Cyclic hardening increases the proportion of elastic deformation and thus improving the springback ratio， while the variable-speed accumulation of inelastic deformation of the spring plate specimens leads to decreae in springback ratio. The higher the fatigue load level， the larger the deformation amplitude of the support structure， the more significant the accumulation of inelastic deformation in the high deformation region of the spring plate specimens， resulting in lower springback ratio. At the end of fatigue， the springback ratios of the outer support structure spring plate specimens are below 35%， and the inner support structure spring plate specimens are in the range of 40%-60%.
