Abstract
The aim of the article was to present issues related to the determination of the impact of selected technological factors: the method of surface treatment and the type of adhesive on the strength of adhesive joints made of C45 steel sheet. The surfaces of the analyzed steel sheet samples were prepared by processing with four different abrasive papers: P120, P280, P320, P800. The sheet samples were bonded with three different epoxy two-component adhesives: Epidian 57/PAC/100:80, Epidian 6/PAC/100:80 and Epidian 62/PAC/100:80, including one-step cure at room temperature of 24 ± 2°C, with humidity 26 ± 2%. After the curing process, strength tests of the adhesive joints were carried out on the Zwick / Roell 150 testing machine in accordance with the PN-EN 1465 standard. It was noticed, among others, that the preferred surface treatment method was surface treatment with the P280 abrasive tool, after which the adhesive joints showed the highest shear strength.
