针对不同挖补斜度的复合材料层合板使用韧性胶黏剂Araldite@2015,对修补后的试件使用弯曲和拉伸性能进行评价.结果表明:铺层方式为[±45°]4s层合板在弯曲载荷作用下修补后修补效率最高能达到119.6％,拉伸载荷作用下修补效率最高能达到71.4％;铺层方式为[0°/90°]4s层合板在弯曲载荷作用下修补后修补效率最高能达到82.1％.结果可为实际修补提供依据和指导.
Factors affecting the effect of repairing damage of composite materials are mainly layer angle,angle and adhesive patch.This paper aims at different patching slope of composite laminates using ductile adhesives Araldite@2015.The repaired specimens using bending mechanical properties and tensile mechanical properties were evaluated.The results show that the overlay [+45°] 4s laminates under bending load repair efficiency can reach the highest of 119.6％,under tensile load repair efficiency can reach the highest of 71.4％;layer [0°/90°] 4s laminates under bending load repair efficiency can reach the highest of 82.1％.These results can provide the basis and guidance for the actual repair.
