The Role of Fiberglass Surface Preparation for Adhesive Bonding

The influence of the surface preparation method of fiberglass VPS–53K on the adhesive strength is researched. To prepare the surface, both standard methods (degreasing, sanding, sandblasting, sacrificial layers) and ultraviolet and normal-pressure plasma treatment are used. The strength of adhesive...

Description
Summary:The influence of the surface preparation method of fiberglass VPS–53K on the adhesive strength is researched. To prepare the surface, both standard methods (degreasing, sanding, sandblasting, sacrificial layers) and ultraviolet and normal-pressure plasma treatment are used. The strength of adhesive joints is evaluated by measuring peel resistance according to GOST (State Standard) R 57832–2017 (ASTM D3167). It is shown that the most effective surface preparation method for bonding is normal-pressure plasma treatment. Through this process the fiberglass surface becomes activated, the fiberglass roughness changes conditionally warpwise and fillingwise, which, together with the ongoing physicochemical processes on the fiberglass surface, leads to an increase in the strength of adhesive joints. The application of normal-pressure plasma improves the wettability of the treated surface with cold-setting liquid adhesives.
