The effects of service temperature on the fatigue behavior of a polyurethane adhesive joint

In order to study the influence of service temperature on the fatigue performance of the adhesive structure, Sikaflex®-265 polyurethane adhesive was used to make thick-adherend shear joints (TASJs) with aluminum alloy. According to the service environment of the vehicle, the temperature points of −40 °C, −10 °C, 20 °C, 50 °C and 80 °C were selected to carry out quasi-static tensile test on the joints, and the change law of failure load and...
