4. Conclusion

The Brazilian test of АMg5 aluminum-magnesium alloy specimens with an interlayer of ED-20 epoxy resin has shown that the composition of the curing agent differently affects the strength of adhesive joints, depending on temperature and the angleα between the direction of the loading force and the adhesion plane. The specimens made with the use of diethylenetriamine as the curing agent have the highest strength at 50 °C. At test temperatures ranging between +25 and +50 °C, higher strength is demonstrated by the samples joined with the use of polyamidepolyamine.
