Tensile behavior of scarfing repaired laminates with half-depth damage

Experimental study on tensile behavior of scarfing repaired laminates with half-depth damage was conducted in the paper. Distinct differences were observed on ultimate strength and failure mode of specimens with different scarf ratio. A finite element model was developed to simulate the tensile behavior of repaired specimens. The calculated results are in good agreement with test results. The numerical results indicate that the scarf ratio is the most important design parameter of repaired specimen. Ultimate tensile strength, failure mode and interface layer damage between repaired and unrepaired sub laminates can be influenced dramatically by scarf ratio. Conclusions of the investigation provide insight into scarfing repair design method on laminates with half-depth damage.
