Abstract

Abstract

Current repair methods for composite honeycomb sandwich panels primarily employ scarf repair techniques, but they are limited by complex procedures and high equipment requirements. Given equipment shortages and time constraints in emergency situations, there is an urgent need to develop rapid temporary repair techniques for sandwich panels. An internal patch reinforcement repair scheme combining operational simplicity with design flexibility was proposed. By drop-weight impact tests and the establishment of a finite element model for low-velocity impact analysis on repaired composite honeycomb sandwich structures, the effects of different reinforcement schemes on impact responses and damage mechanisms were comparatively analyzed through combination of mechanical response curves with failure morphology characteristics. The results indicate that, interfacial voids in conventional patch repairs reduce the impact load-bearing capacity. Due to the increase of contact area during impact, the proposed internal patch reinforcement enhances the impact resistance with a delay of the adhesive failure a constraint on structural deformation. The research provides a theoretical base for rapid repair technologies in composite structures.
