Hybrid composites comprising glass and carbon fibres have significantly increased applications due to their synergetic effect. Fibre hybridisation generally overcomes the limitation of one fabric by the benefit offered by the other fabric. However, during the service life, a structure may undergo various damages because of mechanical load or environmental conditions, which reduces the component's strength. In this work, the carbon-glass hybrid composite was repaired using the adhesive patch repair technique. The post repair behaviour is investigated in high velocity impact, tensile static and fatigue loading environments. In the impact study, the stacking sequence of plies in a patch and the effect of different patches were studied. A 3D finite element model was also developed and validated with the experimental results to understand further the effect of the ratio of glass to carbon ply in a patch. It is observed that the placement of glass plies and the number of glass plies in the patch significantly enhances the impact resistance of the specimen. This 3D finite element model was further modified to incorporate the effect of resin fill in the hole area of a repaired specimen. With the help of the modified model, the effect of patch size and stacking sequence for a fixed parent specimen was studied. In the tensile study, the effect of the patch parent stacking sequence and the patch stiffness were analysed with the aid of digital image correlation and acoustic emission. The least stiff patch with parent laminate having glass ply as the exterior ply exhibited the highest strength recovery during the tensile loading. Furthermore, tensile-tensile fatigue tests were performed for the drilled and repaired specimens to understand the behaviour of parent stacking sequences. In the fatigue environment, the parent specimen with glass plies at the exterior layer performed better than the carbon plies at the exterior layer
