Abstract

This thesis deals with the issue of hybrid material joints in the automotive industrial field, with a particular focus on blind riveting process optimization for composite to aluminum connections. This aspect results from the efforts of modern carmakers to integrate dissimilar materials in the same body-in-white (BIW) structure, in order to improve fuel economy and vehicle performance and meet emission regulations. The thesis first presents a general overview of joining strategies adopted as the alternatives of the conventional spot welding technique, which is not suitable for multi-material joints. The analysis then continues with the benchmark of the main Original Equipment Manufacturers (OEMs) concerning their material integration strategies and current joining technologies. Innovative riveting methods and their experimental performance assessment will be presented, with the target of improving the benchmark data for future FCA application involving lightweight and dissimilar materials.
