Abstract

The paper presents the results of experimental research the aim of which was to compare the load capacity and fatigue life of single-lap joints of 2024-T3 aluminium alloy elements. The test specimens have been connected with adhesive bonding, mechanical fastening as well as by means of hybrid joints (adhesive and screw joints). Specimens with 25 and 50 mm overlaps have been used in the tests and geometry of joints has been modified by changing the mechanical fasteners location; mounted at 2 and 1 fastener hole diameter distance from overlap edge. It has been found that the use of mechanical fasteners in hybrid joints is effective only if appropriate overlap length is used. What is more, it has been empirically proven that the installation of mechanical fasteners in hybrid joints that are closer to the end of the overlap edge (less than the minimum recommended distance for mechanical joints) is justified taking into account the load capacity and fatigue life.
