Content
Adhesive bonding has gained a lot of popularity on the automotive industry on recent years. The technology has helped OEMs to build lighter vehicles by enabling the joint of dissimilar, lighter materials as well as joints that otherwise could not be welded or bolted together due to the lack of machine and operator access. It has also seen widespread usage to enhance crash performance, due to its ability to distribute stress uniformly and absorb energy.
Past test reports had shown that adhesive bonding may have a poor performance when used on Zn-Fe (Galvanneal - GA) coated steel sheets, as the superficial coating layer may delaminate from the base steel, not allowing the adhesive to perform properly.
The objective of this paper is to analyze the performance of adhesive bonding on GA coated steels when utilized alongside weld spots. Two different types of adhesive will be analyzed, preformed tape and pumpable adhesive, applied on both GA coated steel and bare steel without superficial coating. Lap shear test on ambient temperature will be the base for comparison.
