Effect of plasma treatment in Aluminum and composites bonding joints: Shear load tests results

This paper presents the results of simple adhesive lap joint shear strength tests of materials under atmospheric plasma treatment conditions. The effects of surface activation of the shear joint by cold atmospheric plasma in the perspective of the adhesion promotion are discussed. Specifically, the changes in the maximum strength introduced by the plasma of coupon samples of aluminum and carbon fiber reinforced materials. Finally, the results of tests and some conclusions are reported.
