## Abstract
Fiber Reinforced Polymer (FRP) has been widely used in structural repair and strengthening because of its ease of application, corrosion resistance, and high strength-to-weight ratio. Despite these advantages, the reliance on synthetic fibers raises concerns related to the cost and environmental impact, leading to an increasing interest in natural fiber alternatives. This study focuses on the shear bond behavior of Abaca Fiber Reinforced Polymer (AbFRP) sheets bonded to concrete with two different epoxy adhesives and compares their performance with Glass Fiber Reinforced Polymer (GFRP). Experimental tests were carried out using AbFRP specimens (250×25×1.5 mm) and concrete blocks (250×100×100 mm). The parameters evaluated included the shear stress–slip relationship, maximum shear stress, and shear stress–strain response. The results revealed that the type of epoxy significantly influences the bonding performance and failure modes. Two distinct failure mechanisms were identified: debonding or composite failure, and adhesive failure, both typically accompanied by a partial detachment of the concrete substrate. Overall, the findings indicated that AbFRP has a considerable potential as a sustainable and cost-effective alternative to conventional FRP systems in structural strengthening applications.
