    Mecahnical analysis and optimization of adhesive solutions in automotive manufacturing: a study on Loctite adhesives
    Ahammed, Jishan; Domokos, István; DE--Műszaki Kar
    This thesis will provide an overview of the benefits and drawbacks of adhesive and their bonding applications in the automotive industry. Through this research, you will gain an understanding of the significance of adhesive bonding technologies over traditional joints like welded joints, in vehicle design and construction, where the reasons behind the choice of materials and procedures have been specified. This study includes an experiment that is designed to examine and verify the strength characteristics of the cyanoacrylate adhesives Loctite 402 and 408. Additionally, the comparison of the characteristics of the mentioned adhesives on the same kind of alloy materials has been discussed in this thesis. Following the cutting process, the specimens were then glued into a single-lap joint using a different glue for each specimen to compare their strengths. Following the application of adhesives, a portion of the specimens were exposed to standard room temperature and humidity levels. Subsequently, an Instron machine was utilized to conduct experimental tests on the joint of those samples using a lap shear tensile test setup. For every bonded material, the measured load values were presented separately in graphs within the Instron machine. Furthermore, this study compares the outcomes of Loctite 402 and 408 by illustrating the lap shear strength and stress-strain curve analysis. After the data was collected from the machine and exported to an Excel file for each specimen, their outcomes were evaluated to determine which one would be a better solution for automotive purposes. Additionally, it assisted us in determining how to enhance their adhesive solution and bring it into compliance with the industry standards.
