Abstract
Recently, adhesive bonding has been used in functional composite structures. The purpose of this study was to clarify the strength properties for adhesively bonded single-lap joints composed of unidirectional CFRP and metal material adherends subjected to tensile shear loads. Tensile shear experiments using universal test machine were carried out to measure the failure loads of various joints. In addition, the effects of adhesive thickness, lap length and metal side adherend on the tensile shear strength were investigated. From the experimental results, it was found that the tensile shear strength and crosshead displacement increase as Young's modulus of the metal adherend increase. Furthermore, the tensile shear strength became reduced with increasing the lap length. Besides, no regularity was recognized between the adhesive thickness and the tensile shear strength.
