Abstract


This paper presents the results of tests conducted to determine the bonding forces achieved with cyanoacrylate-type adhesives on 7075 series aluminum alloy. This study represents an initial step in assessing the applicability of cyanoacrylate adhesives in the production of bonded assemblies. Specifically, it explores their use for joining aluminum parts that serve identification or aesthetic/design functions.

Driven by significant pressure to reduce manufacturing times, bonding technologies are increasingly employed as non-detachable assembly methods, alongside traditional assembly techniques. A key advantage of bonding is its ease of automation, which can considerably shorten manufacturing cycles.

Based on the tests performed, the tear strengths of the adhesives were determined. Under the test conditions, notable differences were identified in approximately 53% of the adhesives evaluated. The test results suggest potential for use in the applications for which the tests were conducted.
