Failure Behavior of Adhesively Patch Repaired and Different Notched Composite Plates
Abdullah ÇELİK Kadir TURAN Yusuf ARMAN
AbstractIn this study, the failure analysis of adhesively-patch repaired notched composites were investigated experimentally. In the experimental study, eight-layered woven glass fiber reinforced epoxy resin matrix composite plates and epoxy based adhesive were used as materials. Notch types variations, double side repair and single side repair were used as a parameter. The composite plates and patches were used from same materials and the fiber reinforced angle and layer arrangement was taking as [00]8. Four notch types were used in the experimental study. Radial hole in the middle plate (Type 1), semicircular notch on the plate edge (Type 2), a circular hole in the plate center (Type 3) and U notch on the plate edge (Type 4) has been examined for 4 different notch type..Double side patch application on edge notched samples have more increasing strength comparing to double side application on central notched samples.[1]
