## Abstract
This study investigates the shear bond behavior of Abaca Fiber Reinforced Polymer (AFRP) sheets bonded to concrete using a double-sided single-lap shear test configuration, with emphasis on stress transfer, bond-slip characteristics, and failure mechanisms.As a sustainable alternative to synthetic FRP systems, AFRP offers environmental benefits, but its interfacial bond performance with concrete remains underexplored.Two concrete blocks (100 mm × 100 mm × 250 mm) with embedded D19 bars were bonded using AFRP sheets (50 mm width, 520 mm length) and epoxy adhesive, with 250 mm bonded lengths exceeding the effective bond length to ensure full stress mobilization.The concrete achieved a 28-day compressive strength of 21.71 MPa, while AFRP sheets exhibited an average tensile strength of 67.34 MPa, failure strain of 3.36%, and elastic modulus of 4.99 GPa.The novelty of this study lies in the quantification of maximum bond stress and performance variation between specimens, where BAP1 achieved a peak shear stress of 10.7 MPa at 0.80 mm slip, while BAP2 reached 7.1 MPa at smaller slip, demonstrating significant variation (33% difference) attributed to interfacial quality.The predominant failure mode was cohesive failure within the concrete substrate, with a thin concrete layer remaining adhered to the AFRP sheet, confirming that interfacial debonding governs failure and that adhesive bond strength exceeded substrate tensile capacity.The findings provide the first systematic characterization of AFRP-concrete bond-slip behavior using symmetric double-sided configuration, confirming that AFRP can achieve moderate bond strength (7-11 MPa range) suitable for sustainable strengthening applications.
