Abstract
Recently, adhesive bonding has been used in functional composite structures. The purpose of our work was to clarify the characteristics of strength for metal-CFRP adhesive bonded structures. We analyzed four types of single-lap adhesive joints subjected to 3-point bending moment by finite element method. In addition, to validity of FEM analysis, strain distribution experiment using strain gauges were performed. By comparing the results of four different types of joints, we obtained conclusions as follow. Under all joint combinations, each stress component and Maximum principal stress distribution at adhesive layer were singular behavior, and indicated Maximum stress value at edge in longitudinal direction. Maximum stress value at adhesive layer using SS400 as material of one side adherend proved to be the lowest in the four kinds of joint combination.
