The Effect of Dry and Wet Condition on the Mechanical Properties of Hybrid Single Lap
Abstract
The aim of this study is to investigate the strength and mechanical behaviour of similar and dissimilar materials AA7075/E-glass single lap joint. The specimen radially in stack with Araldite epoxy adhesive and mechanical fasteners of Huck bolt with the bondline length of 64 mm for different joint configurations; bolted, bonded and hybrid. The investigation was conducted under two different conditions of dry and wet of 55°C for long water immersion of 120 days. The effect of moisture was defined in hybrid joints as combination of adherend and bonding materials. The tensile test with a speed rate of 1 mm/min was conducted for both condition using 100 kN load cell until total failure of specimen. The experimental results were plotted into load displacement and stress strain curve for each environment. In addition, failure mechanism of the specimens was detected in which occurred at adhesive and Huck bolt.
