Abstract :The metallic bone fracture fixation plates are progressively being replaced by epoxy-reinforced glass fiber laminates (ERGFL) due to a higher strength-to-weight ratio and near neat shape manufacturing. Bone fracture fixation laminates are required to sustain the cyclic load due to the physical movement of the body. Therefore, the characterizations of glass fiber/epoxy laminates with drilled holes are important to study. Despite extensive research on the mechanical characterization of composite laminates, several unique circumstances remain unexplored, such as the characterization of glass fiber/epoxy laminates with drilled holes. The drilling laminates weakened the laminates\' mechanical strength and damaged the area around the drilled hole. With Jo drill point designs, the greatest thrust forces (0.56 kN) were observed at 2800 rpm of cutting speed and 0.19 mm/rev of feed rate. Among the various drill points used, the drilled ERGFL laminates with Jo drill had the maximum fatigue life cycle of 87×103.
