Abstract

Structural adhesive bonding technology is widely utilized in various applications in modern automotive and aviation industries. Finding new techniques to enhance adhesion strength between bonded components in a more economical and environmental-friendly way is becoming an important issue. In this paper, a novel micro-surface texturing method by using a developed deformation-based micro-rolling system has been applied to modify surface conditions of a sheet metal in order to increase metal-to-metal adhesion strength. Additionally, different surface texturing patterns, such as micro-channel arrays and grid pattern, are produced by single-pass or two-pass micro-rolling strategies. The effect of these texture patterns on adhesion strength is studied through single-lap-joint shear strength test. Results indicate that surface with micro-textures are able to achieve noticeable improvement in adhesion strength.
