摘要：

As the composite material of fiber reinforced plastic has the high strength with light weight unlike exiting metal materials, its usage is being gradually increased. In this study, the fracture behaviors are investigated with CFRP and existing metals of aluminum, brass and structural steel by 3-point bending test. As existing metal materials, the maximum reaction forces of 2250 N, 2500 N and 2400 N occurred at aluminum, brass and structural steel respectively. In contrast, the maximum force of about 4000 N was shown at CFRP. This study result can be applied to the durable design of composite structure.
