“…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.

In recent years, bonding joints are the most effective way to successfully and safely combine different materials in sectors such as automotive, aircraft and aerospace industries. In particular, the combination of composite materials, such as rivets, welds, non-conformity of traditional methods have been made use of bonding joints. The fracture behavior of the adhesive is important in adhesively bonded. In the present study, the fracture behavior of the adhesive was investigated experimentally under Mode-I loading of Double Cantilever Beam (DCB) joints obtained by using materials of different width and thickness. AA2024-T3 aluminum is used as the adherend and two component Araldite 2015 tough adhesive is used as adhesive. The fracture progression during the experiment was measured with a high-speed camera and the displacement was measured by a video extensometer. As a result; when the fracture energies of the experimentally obtained adhesive are examined, the fracture energy of the joint changes when the width and thickness of the adherend changes. In addition, the fracture energies of the joint obtained with the Corrected Beam Theory (CBT) and the Standard Test Method (SBT) are compared, and the fracture energy obtained with CBT is more accurate considering the elastic rotation in the adherend.

Micro-hot embossing is a highly effective process for fabricating micro-devices with microfeatures in polymeric materials. One of the most troublesome problems in precision machinery industry is the time and expense needed to produce a mold for microreplication. Epoxy resin mold has been successfully employed for microreplication using micro-hot embossing. However, the junction of the groove and sprue of the backing plate has serious local stress concentration, leading to the reduction of lifespan of a precision epoxy resin mold during the micro-hot embossing molding. This work presents an effective method for enhancing the lifespan of a precision epoxy resin mold using reduction of local stress concentration. The numerical models were developed for predicting the maximum stress using ANSYS software. The ANSYS simulations have been carried out and the predicted results show good agreement with experimental tests. The junction of the groove and sprue of the backing plate was machined with chamfer to revaluate lifespan of the epoxy resin mold using micro-hot embossing molding. Micro-hot embossing verification test showed that the lifespan of epoxy resin mold with chamfer is about 2.2 times that of the conventional epoxy resin mold.
