First of all, Nanocomposite adhesive was produced by adding different weight ratios of nanoparticles into polyurethane adhesive. Then, the tensile test samples were produced using these adhesives and tensile tests were performed in accordance with the ASTM D 882 standard. According to the obtained results, the additive ratios showing the best mechanical properties were determined and single lap joints (SLJ) were produced. Then, the mechanical properties of the SLJ were tested in accordance with the ASTM D1002-10 standard under a constant tensile loading ratio. The highest tensile strength was observed in the 05GR15CNT sample with an increase of 52.67% (14.58 MPa) among the tensile test specimens. On the other hand, the highest shear strength was obtained in the 10GR10CNTSLJ sample with an increase of 14.80% (15.51 MPa) for the SLJ specimens. The distribution of the nanoparticles and the morphology of the failure surfaces were analyzed by scanning electron microscopy (SEM) images.}, number={1}, publisher={Parantez Teknoloji}, organization={NECMETTİN ERBAKAN ÜNİVERİSİTESİ}
