The aim of the article was to determine the strength of the adhesive joints of the carbon steel and aluminium alloy. Two types of two-component epoxy adhesives were used in the tests: rigid and flexible. Rigid epoxy adhesive contains epoxy resin based on Bisphenol A and triethylenetetramine (TETA) curing agent, in a ratio of 100 g resin to 10 g curing agent. Flexible epoxy adhesive contains epoxy resin based on Bisphenol A and polimaminoamide curing agent, in a ratio of 100 g resin to 100 g curing agent. The tested adhesive joints were subjected to conditioning at room temperature (23 °C) and humidity 35% (the first version) and subjected to thermal shocks (500 cycles: + 60 °C/−40 °C)—the second version. Strength tests of different variants of adhesive joints were performed on the Zwick/Roell Z150 testing machine in compliance with the DIN EN 1465 standard. Shear strength and elongation at break were determination. The obtained results have shown that in some cases, depending on the type of adherend, the adhesive joints exhibit greater elongation after a specified time of thermal shocks compared to non-thermal adhesive joints. |
