The research described in this article is part of investigating impact strength in block adhesive joints. The authors checked experimentally the effect, on the test results, of the manner of surface preparation and compressive strength and Young’s modulus of an adhesive used to make the connection. The experimental testing was carried out with an impact pendulum tool, designed to examine adhesive joints. During such testing, the energy used to tear off the upper part of the specimen, that is the energy lost by the dropping device, is the measure of the impact strength of an adhesive connection. The elements of the samples were made with an aluminum alloy 2017A. In the investigations, the authors used non-normative samples whose upper element was a cylinder rather than a cuboid, as advised in the norm. The adhesive joints were made using epoxy adhesive Loctite, named EA 3421, or an adhesive composition Epidian 57 with Z1 hardener. The glued elements were prepared by treating the surfaces for bonding by means of the stream-abrasive processing. The abrasive mediums were three types of materials of different gradation. In addition, two series of samples were prepared using roughening by sandpaper. For control samples, the authors made joints, in which the surfaces for bonding became degreased merely by petroleum ether. The results of the experimental studies indicate that the impact strength of adhesive joints is dependent on the manner of preparation of the bonded elements as well as on the longitudinal modulus of elasticity of the adhesive, which was used to make the connection.
