Three weight percentages of bagasse flour namely 40, 55 and 70 percent were chosen. MAPP was used as coupling agent at two weight percentages namely 4 and 6 percent. Bending strength was measured applying Instron 6025. Fracture surface was stadied using SEM to evaluate the interface between plastic and fiber. The results showed that with increasing bagasse, stress and work at yield point of bending was decreased and modulus of bending was increased. Also, increasing coupling agent resulted in improving stress, modulus and work at yield point of bending. SEM results showed that with increasing coupling agent, interface between plastic and bagasse fibers was improved.
