| Abstract | This paper investigates the effect of bonding pressure, overlap length and adherent thickness on the strength and failure load of the single-lap joints of dissimilar materials (GFRE composite and aluminum). Eighteen groups of joints made of glass fiber epoxy composite laminates and Al have been manufactured. The stacking sequences [0/±45/90] and [0/±45/90]s were used to manufacture 2 mm and 4 mm thick GFRE composite laminates, whereas Al thickness was 1.5mm and 3mm. In all cases, the CY219 adhesive thickness was 0.12 ±0.02 mm, and the specimen width was 25mm. Besides, various values of bonding pressure [1, 2, 3, 4, 5, 6 atm.] were applied. The experimental results show that, the failure load and strength of the joint increase with bonding pressure up to 4 atm. Higher bonding pressures do not considerably affect the failure load and strength. Hence, a bonding pressure of 4 atm. was found suitable for bonding composite to aluminum. Moreover, the failure load increased and the bonding strength decreased with increasing the overlap length. However, the increase of failure loads slightly at overlap lengths larger than 30 mm. Also, increasing the adherent thickness resulted in an increase of the failure load. Finally, the failure mode of tested joints was composite delaminating. ت ةصولل راةيرنلاا لةمحو ةلةصولا ةةمواقم ىلع ةقوصلملا تانيعلا كمسو قابطنلاا لوطو طغضلا ريثأت ةسارد مت ثحبلا اذه يف موةةينمولاا مةةم ةةةيداحاا ةةةيبكانتلا – وةةتحا ىةةسكوبياا ماد تةةساب ةقوةةصلملا و ةةةيااا ااةةيلأب اوةةقملا ىةةسكوبياا اةةلتؤمو عومام ةرشع ينامث يلع يلمعلا جمانربلا ة طغةض ةداةي ةم ماداد يرايرناا لمحو ةلصولا ةمواقم مأ ةيلمعملا جئاتنلا تررظأ بةسانم ودةبي ةةعبرأ اوةالا طغةضلا ماف كلذلو اوا طغض ةعبرأ دعب ةفيفط موكت ةداي لا مكلو طبارتلا ا ةةفلتؤملا داوةمل ا قةصلل ةمواقم لةقتو راةيرنلاا لةمح داد ةي قاةبطنلاا لوةط ةداةي ةم موينمولااو لةمح داد ةي تاةنيعلا كمةس ةداةي ةم كلذةكو ةلةصولا ة رايرنلاا |
