The paper presents an evaluation of joints resulting from adhesively bonded aluminum sheets. The aim of the study was to assess the possibility of applying this type of connection for the construction of composite beams. The results of experimental tests on the shear test of joints are presented. Four types of connectors were the subjects of the research. The joints of the same geometry were made of four 1.6 mm thick sheets of aluminum alloy AA 7075-T6. Each type of joint was characterized by a different material joining the sheets: three of them were connected by acrylic foam tapes, one joint was made using two component toughened methacrylate adhesive. Three different double-sided acrylic foam tapes with different properties were tested. It has been assessed that the two-component toughened methacrylate adhesive can be used for the construction of the aluminum core applied in composite structures.
