“…Ionized gases can elevate the surface energy of polymers, ionize neutral substances on polymeric surfaces, generate reactive species (such as OH and NH-bearing groups), activate atoms, and nano-modify the surface. Because of the ionized molecules, an extremely high-energy plasma is produced [20]. Many kinds of plasmas have been used in industry and are produced in research laboratories.…”

The objective of this study is to investigate the effect of air (dielectric barrier discharge) DBD plasma treatment on the bonding strength of adhesively bonded glass fiber-reinforced epoxy composite-aluminum lap joints. The bonding performance of lap joints produced by the plasma treatment was compared with that of untreated and peel-ply surface treatments. Water contact angles of the substrates were measured for untreated, peel-ply, and plasma surface-treated substrates. Experimental results showed that plasma-treated aluminum and GFRP substrates increased the wettability properties and thus shear strength of adhesively bonded GFRP-Al joints increased. After the shear tests, the fracture surfaces of the substrates were visually examined and three different damage modes were observed, including light fiber tear failure, adhesive failure, and thin layer cohesive failure modes.
