Abstract: In a metal and fiber reinforced epoxy hybrid with composite structure, weakest point is interface of metal surface and fiber patch (Adhesive layer). In this study single lap joint in some specimens with different weight fraction of multi wall carbon nanotubes in composite part, tested in functionalized and non-functionalized situation and shear strength between polymer matrix and alloy aluminum investigated. Based on obtained results, Samples contain non- functionalized carbon nanotube showed a positive effect on shear strength in comparison with specimens contain the same amount of functionalized nanotube. It was completely obvious from test results, shear strength between composite patch and aluminum 2024-T3 surface has been increased with CNT while aluminum has not been chemically affected by CNTs.Key words: Epoxy hybrid Adhesive layer Carbon nanotube and matrix Single lap joint E-glass/Epoxy Composite
