Effect of cyclic hygrothermal aging on mechanical behaviours of adhesive bonded aluminum joints

This paper focuses on the effect of cyclic hygrothermal aging on the mechanical behavior of the adhesive bonded aluminum joints. The adhesive joint specimens were immerged in the temperature/relative humidity set at 80 °C/95％ and −40 °C/30％ for cycle experiments for un–aged, 20, 40, and 60 cycles, respectively. Joint bonding angles were set to 0°, 15°, 30°, 45°, 60°, 75° and 90°. The stress modes of the adhesive joints were directly related to...
