This work presents experimental results on the performance of Aramid Fiber Reinforced Polymer (AFRP) laminates used inthe flexural retrofitting of full-scale reinforced concrete beams. The effects of variables including reinforcement placement,retrofitting orientation, and AFRP lifespan are examined. The experimental findings provide compelling evidence thatstructurally damaged beams can be retrofitted with AFRP composite material to restore their strength and stiffness. In mostcases, the retrofitted beams perform as well as, if not better than, the control beams. The efficiency of the AFRP strengtheningmethod in flexure, however, was found to vary with beam length. The examinations revealed that plate debonding was theleading cause of the failures observed. In order to overcome this difficulty, it is crucial to enhance the bonding processesbetween the AFRP laminates and the concrete substrate.
