Vliv teploty na pevnost lepeného spoje

Abstract

This bachelor thesis focuses on analyzing the effect of temperature on the strength of adhesive joints. The experiments were conducted on test specimens made of EN AW 5754 aluminum alloy, bonded with the two-component epoxy adhesive 3M Scotch-Weld 7260 B/A FC. The theoretical part deals with the characteristics of adhesive bonding, classification of adhesives, and an overview of methods used for testing mechanical properties. The experimental section describes the entire procedure of specimen preparation and the execution of tensile tests. The measured data are presented in the form of tables, graphs, and photographic documentation of the fractured joints. The final part of the thesis compares the joint strength at different temperatures and contrasts the results with the values provided by the adhesive manufacturer.
