“…An alternative method for increasing adhesion in polymer laminates is CF surface treatment with cold plasma [ 30 , 31 , 32 , 33 ]. In this method, it interacts with ions, free electrons, excited atoms and molecules, as well as radicals, increasing the free energy and forming active polar groups [ 34 , 35 , 36 ]. In addition, microroughness increases on the surface of CFs upon plasma treatment, which, according to the mechanical interlocking theory [ 37 , 38 , 39 ], contributes to an additional increase in adhesion between fibers and polymers [ 40 , 41 ].…”
