Abstract

Use of hybrid joining systems to enhance the structural performance of coated thin high strength steel sub-assemblies Significant weight reductions for steel automotive structures have been achieved by the substitution of mild steel with thinner high strength steel grades in selected parts of the vehicle architecture. Further reductions in sheet steel thickness are inhibited by the loss in torsional stiffness and fatigue performance when using conventional joining techniques. Continuous joining techniques such as adhesive bonding, combined with an additional joining technique such as spot welding or mechanical fastening, provide a means of restoring both torsional stiffness and fatigue performance. This project has therefore aimed to establish the potential of hybrid joining techniques in sheet steel assembly. The compatibility of different adhesive types with the various mechanical fastening and welding techniques has been determined and appropriate process parameters for each hybrid technique have been developed. Mechanical tests have been conducted, and the data used as the basis for a detailed stress analysis of various types of joints.
