Zero-emission joining methods for low-load automotive structural components

Abstract

The article contains general information on the bonding of aluminum sheets, taking into account the most commonly used methods of surface preparation of sheets, a description of the bonding mechanism and a comparison of the different types of adhesives used in the industry, a summary table provides information on the most commonly used adhesives used in the industry. In addition, the static tensile test of aluminum alloys used in the automotive industry is described. In the following part of the article, the research problem of bonding strength of sheet metal by gluing with two types of two-component adhesive Epidian 57 and Epidian 53 is solved. In the practical part of the research, aluminum alloy 2024 - T3, the most commonly used alloy for the production of low-load structural components used in the automotive and aerospace industries, was used. The test consisted of gluing together two overlapping (overlap bonding) sheets of metal with different types of adhesive using a specially designed device. The thickness of the sheet used was 1mm, the total thickness was 2mm. After the gluing process, the samples were torn on a testing machine. The results are shown in a summary table and presented in a graph.
