Analysis of impact resistance of polyurethane reinforced honeycomb core sandwich structure
摘要
Abstract
To investigate the effect of polyurethane coating on the impact resistance of honeycomb sandwich structures,the impact response of composite sandwich structures with polyurethane coating applied to the inner walls of honeycomb cores under low-velocity impact conditions was analyzed.Based on the validated numerical model,a numerical analysis was performed to examine the low-velocity impact behavior of composite sandwich panels with varying coating thicknesses.Multiple indicators were employed to analyze the influence of coating thickness on the impact resistance of the composite sandwich panels.The results indicate that the honeycomb sandwich structure with a 0.5 mm thick coating on the inner walls exhibits an 11.11%reduction in the honeycomb core indentation depth and an 11.98%decrease in the indentation diameter along the impact direction.This method effectively enhances the impact resistance of honeycomb sandwich structures.关键词
