Experimental investigation of tensile behavior of hybrid laminates repaired by scarfing method based on k-sample anderson-darling test

Experimental study on tensile behavior of hybrid plain woven fabric laminate repaired by scarfing method was conducted in the paper. In order to analyze experimental results, k-sample Anderson-Darling test was adopted in the study to investigate the influence of scarf ratio, repair methods and initial damage diameters to the tensile behaviors of repaired specimens. Experimental results indicate scarfing repair can recover the tensile strength of laminate well. After thorough comparison, the study demonstrates that the tensile strength of full depth scarfing specimen can achieve the level of intact panel when scarf ratio exceeds 1: 20 and for half depth scarfing specimen, the threshold of scarf ratio is 1: 10.Test results also reveal when the scarf ratio is fixed, changing the diameter of initial damage could hardly affect the tensile strength and failure mode of scarfing repaired specimens. Conclusions of the investigation provide insight into scarfing repair design method on hybrid plain woven fabric laminate.
