| Abstract Scope |
Adhesive bonding of lightweight multi-materials, including high strength aluminum alloy, carbon fiber reinforced composites and advanced high strength steels, were investigated as a viable joining technique for lightweight vehicle applications. In this presentation, different surface modifications methods were applied on the selected substrates to enhance the bonding between the adhesive and material substrates so that the joining interface can achieve higher adhesive bonding strength. Optical and advanced characterization techniques were used to study changes of morphology, local chemistry, and/or surface energy on the substrates before and after surface modification. Lap shear tensile testing was performed to study the bonding strength before and after corrosion exposure performed per ASTM B117. This presentation will report the corrosion attacks adjacent to the bonded lap joint area and the change of boding strength with increasing corrosion exposure time. |
