In 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]
