Abstract Periodic cell wall loss is a typical defect in brazed honeycomb sandwich panels, which can lead to a decrease in the mechanical properties of the honeycomb sandwich panels. In order to predict and evaluate the impact of cell wall loss on the compressive mechanical properties of honeycomb sandwich panels, a defect free finite element model of honeycomb sandwich panels was first established, and the simulation model was validated through theoretical model. Furthermore, by parameterizing the periodic cell wall loss, a honeycomb sandwich panel model with pe-riodic cell wall loss was established, and the influence of the center distance, angle, length, and width of periodic cell wall loss on the flat compression mechanical properties of the honeycomb panel was explored. A prediction model for the compressive strength of honeycomb sandwich panels with periodic cell wall defects was constructed based on response surface methodology, and sensitivity analysis was conducted using Sobol method. Finally, the kernel density estimation method was used to determine the 95% confidence interval for the elastic modulus and maximum bearing capacity of the defective honeycomb sandwich panel. The results indicate that the accuracy of the prediction model is good, with a maximum error of no more than 1%. The elastic modulus is most sensitive to the periodic loss length, and the distance, length, while width of the periodic cell wall loss center have a significant impact on the maximum bearing capacity. At a 95% confidence interval, the elastic modulus of ho-neycomb sandwich panels with periodic cell wall loss drops to 93.14%—99.06% of the ideal value, and the maximum bearing capacity drops to 94.11%—99.49%.
