Abstract

This article focuses on the effect of curing temperature on the strength of adhesive joints used in vehicle prototypes. Testing the influence of curing temperature on the adhesive joint was carried out on samples of aluminum alloy EN AW 5754, with the adhesive surface prepared by abrasive blasting. Samples of aluminum alloy were bonded using three types of two-component adhesives. Two types of adhesive joints are addressed here. Firstly, adhesive joints cured at +20 °C for 168 hours, and secondly adhesive joints cured at +80 °C for 1 hour. The samples are tested using a tensile test, and the resulting data is plotted in graphs in the experimental section and compared. The achieved results of the experimental activity are discussed in the conclusion.
