the adherends. Fatigue tests were conducted using uniaxial electro-hydraulic fatigue testing system; frequency was f = 10 Hz, and stress ratios (ratio of minimum stress to maximum stress in one cycle of loading) were R = −1, −0.5, 0.1, 0.5, 0.7 and 0.9. All of the tests were conducted in a laboratory environment at a room temperature of 23 ± 3 °C and a relative humidity of 50 ± 5%.
