Especially in the aviation industry, using of composite materials has gradually increased to improve the energy efficiency and to reduce the weight. However, since the composite materials such as glass fiber based composites have very few of the electrical conductivity, it causes lightning strikes on aircraft, nonmoving of static electricity (due to the friction effect)over the surface of aircraft and cause damage on aircraft. Therefore, it is usually tried to be glued aluminium layer to different layers of the composite layers for obtaining electrical conductivity. Bonding technique of dissimilar materials is changing according to mechanical, chemical and physical properties of the materials. Therefore, determining of the proper adhesive is important. In this paper, the effect of different adhesives, which are used for bonding of glass fibre composite with aluminium plates, on the mechanical properties have been experimentally investigated.
