Recently the more complex properties have been required in the design of composite structures. In some cases, those requirements cannot be attained without joining of a composite structure to another. A single-lap joint structure is one of most popular joint structures, and its static poperties has been reported by many researchers. However the dynamic properties of this structure have not been significantly clarified. In our previous work, a new numerical modeling method of the CFRP single-lap joints structure was proposed, and the eigenvibration problem was simulated.In this modeling method, the heterogeneity of the single-lap structures could be considered in such a way that the adherend and adhesive layer were independently modeled by two types of finite elements. In the present report, the influences of fiber orientation angles in adherend and single-lap geometries on the vibration properties is discussed by using the proposed numerical modeling. The advantages and validity of the modeling method are shown in details.
