A Study on Mechanical Properties and Durability Evaluation of Structure Adhesived and Spot Welded Joints

Abstract:

Article Preview

Structure adhesive bonding method is widely used in the industry because it is possible to joint complex shape and dissimilar materials. Especially in the car industry, requests of lightweight car have adhesive bonding method be applied in the many parts. Also it is possible for stress to distribute uniformly through the adhesive layer, and stress concentration is released. Since strength, stiffness durability is much better, this method is determined as the technique replaced weld defect. But, it has much shorter history then other joint method such as spot weld and mechanical joint method. Evaluation of strength and durability is not established. As the fundamental research of design of adhesive bonding joints, considers over-lap length, adhesive thickness, surface treatment and environment which affect strength and durability of single-lap joints. In this research, a real part of bus folding door was used and tested to compare durability of spot welding and adhesive bonding.
