Aiming at the problem of heavy mechanical structure of the exoskeleton backplate, a lightweight backplate of T700 carbon fiber reinforced hollow glass microspheres/epoxy composite based on sandwich structure is proposed in this paper. By analyzing the influence of the thickness of face layer and core layer on the mechanical properties of composite sandwich structure, a composite backplate structure with face layer thickness of 4mm and core layer thickness of 8mm is designed. The simulation calculation and test of the sandwich backplate were carried out. The results show that the error between the simulation results and the experimental values is small, and the reliability of the results is high, which provides more lightweight design of the exoskeleton backplate.
