LINK BETWEEN THE ENERGY CHARACTERISTICS OF THE SURFACE OF FIBERGLASS OF THE VPS-53К BRAND AND THE STRENGTH OF THE ADHESIVE JOINT BASED ON IT
Based on the study of the wetting phenomenon and the theory of adhesion, the surface of fiberglass of the VPS-53K brand was studied before and after its treatment with atmospheric pressure plasma, which is one of the advanced methods of surface preparation for various adhesion processes. Two methods for determining the free energy of a surface are considered - the OUN's, Wendt's, Rabel's, and Kjelbla's method and the extended Fowkes method. The values of the free energy of the surface and its components are obtained using two methods under consideration. The connection between the energy characteristics of the surface of fiberglass of the VPS-53 K brand and the strength of the adhesive joint based on it is established.
