对挖补修理后的平面编织混杂铺层层合板的拉伸性能进行了试验研究,使用k-样本Anderson-Darling检验对试验结果进行分析,研究挖补斜度、不同修理方法以及初始损伤直径对修理效果的影响。试验结果表明:挖补修理可以较好地恢复层板的拉伸强度。对穿透挖补修理,挖补斜度大于1:20后,修理试件的拉伸强度可以恢复至完好板的水平;对半穿透挖补修理,挖补斜度大于1:10即可保证修理试件的拉伸强度达到完好板水平。此外,仅改变初始损伤直径不会对修理试件的拉伸性能造成明显影响。以上结果对混杂铺层层板的挖补修理设计有一定的指导意义
Tensile properties of digging and repairing plain-woven hybrid ply laminate were studied. The results of Anderson-Darling test were analyzed using k-sample. The effects of digging slope, different repair methods and initial lesion diameter on repairing performance Impact. The test results show that digging and repairing can well recover the tensile strength of the laminates. For penetrating digging and repairing, the tensile strength of the repaired specimen can be restored to the level of intact plate after digging compensation gradient is greater than 1:20. For the semi-penetrating digging and repairing, the digging compensation gradient is greater than 1:10 to ensure the repair of the test specimen Tensile strength reached the level of intact board. In addition, simply changing the initial lesion diameter will not have a significant effect on the tensile properties of the repaired specimen. The above results have certain guiding significance for the design of digging up and repairing of the mixed laminated ply
