Drilling of composites is essential and a prerequisite process for enabling secondary joining related to bolted connections. Composites are widely employed across various industries due to their superior mechanical properties and adaptability. The study explores the mechanical performance of GFRP/Epoxy composite laminate, focusing on the effects of hole drilling and subsequent repairs on their structural integrity. Each specimen, measuring 250 * 36 mm with a uniform thickness, featured a centrally drilled 6 mm diameter hole. The study compared pristine samples without holes against those that were drilled and subsequently repaired. The repair work included glass, carbon and Kevlar fibers and hybrid combinations of these materials (G + C, G + K, and C + K) as double patches measuring 36 * 36 mm on both sides of the drilled holes. The mechanical properties assessed primarily focused on tensile strength and damage tolerance. Results revealed a notable enhancement in tensile strength across all repaired samples, with hybrids showing variable improvements depending on the fiber combination used. This research not only underscores the efficacy of double patch repairs in restoring the mechanical integrity of drilled composites but also broadens our knowledge on optimizing repair techniques for mixed-fiber composites in diverse practical applications. It is further made clear that kevlar based patch exceeded the tensile strength followed by Carbon and hybrid glass carbon patch performed well in the test.
