As CFRP as the single material has various material properties, it has been used at many fields. CFRP is utilized at the mechanical structure on the basis of the brittle fracture property and the performance of vibration damping. CFRP composed of multiple axes has the high natural frequency. It is shown to have more reinforced material property with the fiber design. This paper investigates the fatigue property of the bonded specimen for mode 1 at the laminate angles of 30°, 45° and 60°. According to the fiber design, each specimen bonded with the laminate angle is shown to have different fatigue property repectively. As the laminate angle is increased, the reaction forcetends to be increased. In this paper, the laminate angle through the fiber design of CFRP is applied and the fatigue property at mode 1 is investigated. Through the study result, The safety of fatigue fracture is also checked at applying to the composite structure.
