Abstract
The paper presents the experimental research focused on the impact of selected technological and operational factors on the strength of adhesive joints of titanium sheet. The single-lap joints of titanium sheet of 0.64 mm thickness were tested, which were subjected to shear. The type of adhesive as technological factor and seasoning time in ambient conditions as operational factor were considered. Two types of two-component epoxy adhesives: Epidian 57/PAC/100:100 and Epidian 57/Z1/100:10 were used. Three variants of the seasoning time: 14, 21 and 28 days and prepared reference samples, for which the curing time was 7 days, were tested. Curing is carried out at an ambient temperature of 25 ± 2°C. The adhesive joints were destructive tested. The shear strength, in accordance with DIN EN 1465, were tested in Zwick/Roell Z150 strength machine. On the basis of the results of research it has been noted that the largest shear strength of CP2 titanium sheet adhesive joints preparing by Epidianu 57/PAC/1:1 was obtained. In addition, in both cases of tested CP2 titanium sheet adhesive joints making by epoxy adhesives Epidian 57/PAC/100:100 and Epidian 57/Z1/100:10, the highest values of the strength of these joints were achieved after 7 days of curing.
