“…Therefore, the joining process of the components is one of the most sensitive points when building the structure and is of great importance. The applications of welding, bolting, riveting, and adhesive bonding are seen as the most common joining techniques used in scientific studies and industrial applications (Kumar et al, 2021;Wang et al, 2022;Gamdani et al, 2022). Among them, the adhesive bonding technique is frequently preferred especially in the automotive and aerospace industries, with its superior aspects such as enabling uniform stress distribution, weight reduction, aesthetic appearance, ability to combine different materials, and eliminating possible chemical reactions by preventing direct contact of the bonded materials (Adin, 2013;Akpınar, 2013;Adin and Kılıçkap, 2021;Atahan and Apalak, 2022;Uzun and Akçadağ, 2022).…”

In the current study, the effects of hybrid nanoparticles on the shear and fracture behaviours of adhesively bonded single lap joints (SLJs) using Aluminum substrates were investigated. To this aim, nano-silica and graphene nanoplatelet (GNP) particles were used as filler materials in Araldite 2014-2 epoxy-based adhesive. The SLJ samples prepared at seven different configurations were subjected to lap shear tests. Additionally, macro and SEM views taken from damaged surfaces of the samples were examined to understand the influence of nanoparticle addition on the fracture characteristics of the joints. The experimental findings showed that all nanoparticle-doped samples, whether single or hybrid, exhibited remarkable improvements in shear strength compared to pure ones. The maximum improvements were obtained from the H2 sample having 1 wt.% nano-silica and 0.5 wt.% GNP. The maximum shear strength was 13.62 MPa which was 213% higher than pure samples (4.35 MPa). It was determined that some toughening mechanisms such as crack deviation, crack bridging and plastic void formations had a crucial role in the enhancements of the samples. However, higher amounts of nanoparticle inclusion such as H4 (1.5 wt.% nano-silica+1 wt.% GNP) showed a decrease in shear strength, compared to the maximum one, due to the material degradation caused by agglomerations. In conclusion, nano-silica and GNP particles proved they could be used together by exhibiting a synergetic effect in the adhesive joints.
