Investigation failure behaviours of notched composite plates repaired with using adhesive and patch. Mechanics of Advanced Materials and Structures, 1-13.1537-64941537-6532https://doi.org/10.1080/15376494.2023.2301506https://hdl.handle.net/11468/17014In this study, the damage behaviors of different type-notched composite plates repaired with composite patches were investigated experimentally and numerically. Eight-layer woven glass fiber reinforced epoxy resin matrix composite plates and epoxy-based adhesive were used as materials. Notch type's variations, adhesive thickness, patch length; double-side repair and single-side repair were used as parameter. Although the same size patch was used, the load values varied due to the different positions of the notches. Notched composite samples with the same area dimensions but different locations have different tensile strength values. Patching and bonding processes have different effects on notched samples with different tensile strength values. A feature of this study is that many parameters were compared for many samples under the same experimental conditions in order to improve repair quality and durability in an understandable way. As a result of the repair process, the failure loads were increased from 47% to 307% ratios according to parameters.eninfo:eu-repo/semantics/closedAccessComposite platesProgressive failure analysisRepair with patch and adhesiveTensile testNotched platesArticleWOS:0011505731000012-s2.0-8518391761910.1080/15376494.2023.2301506Q1N/A
