This study aims at investigating experimentally flexural performance of reinforced concrete (RC) beam reinforced with polyethylene fiber (PEF) sheets. The PEF sheets were bonded on the soffit of the beam using epoxy resin adhesive. RC beams reinforced with carbon fiber (CF) sheets were also tested. Obtained results are as follows. The maximum strength increases and the deformation capacity decreases with increase in number of sheets for both the reinforced beams. The CF sheets and the PEF one mainly make a contribution to increase of the maximum strength and the deformation capacity respectively. A fairly good agreement between the measured values and the calculated ones is obtained for flexural performance of the reinforced beams until separation of sheets occurs.
