Fiber reinforced sandwich composites are frequently used today. The inability to recycle these frequently used materials ensured that the repairs of these materials became more important. There are a several different methods developed on this area, but most of them are basically based on the patch repair method. In this study it is aimed to improve the efficiency of repair with newly proposed patch types to be applied during the patch repair process, which is used in the repair of sandwich composites. Sandwich composite plates were made of glass fiber, PVC foam and epoxy resin with vacuum assisted resin infusion method. Prepared specimens were subjected to the three-point bending test taking into consideration parameters such as specimen width, damage diameter and the results were evaluated. As a result, it has been seen that the proposed methods significantly affect the efficiency of patch repair.
