Generally, Fiber Reinforced Plastics (FRP) have been regarded to have same mechanical properties if reinforcing fibers, reinforcement configurations, matrix resins, surface treatment and volume fraction of fibers are same regardless of molding method. However, it is considered that interface properties are changed by impregnating process among hand lay-up method and VaRTM method. In this study, effects of difference in molding method on mechanical properties and fatigue properties of FRP were investigated. As a result, static tensile properties, low-cycle fatigue properties and interlaminar fracture toughness were changed by molding process..
