| 摘 要： | 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。

| Abstract: | 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%; layer0°/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. |
