Fiber reinforced polymer (FRP) reinforcing bars for concrete structure, as a non-corrosive material, has been extensively investigated by many researchers. However, it has not been practically used as the reinforcement or structural material in civil engineering structures due to its low elastic modulus if glass fibers were used. This study was motivated to overcome this shortcoming of FRP bars to be used for concrete structures. Material hybridization was applied to enhance its elastic modulus. The effect of material hybridization was evaluated by comparing the results of tensile test with those of non-hybrid FRP bars.
