Tensile Shear Strength Characteristics for Adhesively Single-lap Joints Composed of Quasi-isotropic Laminated CFRPs and Aluminum Alloy
The purpose of this study is to clarify the strength characteristics of the single-lap joints in which quasi-isotropic laminated CFRPs and an aluminum alloy are adhesively bonded and subjected to tensile shear load. Stress distribution at the adhesive layer was investigated by using three-dimensional finite element stress analysis, and joint strength was measured by tensile shear test. In addition, the effects of the lamination configuration of the quasi-isotropic laminated CFRPs on the adhesive layer stress distribution and tensile shear strength were examined. According to the analysis results, it was suggested that if the fiber direction near the adhesive layer was inclined, an asymmetrical stress distribution would occur. From the experimental results, it was confirmed that the tensile shear strength tended to increase as the fiber orientation angle near the adhesive layer approached the longitudinal direction of the joint.
