Based on the experimental results and the theoretical analysis and finite element simulation results, the influence of the strength of the outer panel on the mechanical behavior and the bearing capacity of honeycomb sandwich structure was studied. The effects of compressive and tensile load on the honeycomb sandwich structure The effect of outer ply reinforcement on its failure mode is discussed. The influence of outer ply reinforcement on its bearing capacity is also given. It provides a reference for engineering use and repair of honeycomb sandwich structure with defects.
