Failure Behavior of Aluminum-Titanium Hybrid Seams within a Novel Aluminum-CFRP Joining Concept

Abstract

Modern light weight designs include various materials to create specific local properties. Hence, joining of dissimilar materials is an important task, especially the combination of carbon fiber reinforced plastics and aluminum alloys is a favored choice. In this paper, investigations on a novel joining concept for these materials are shown carried out within the DFG research group “Schwarz-Silber” at the University of Bremen. A titanium transition structure consisting of a foil laminate is applied. On the aluminum side joining is realized by a simultaneous double-sided laser process. In the results the failure behavior of this joint is characterized.
