“…They observed that, for 0.5 and 0.8 wt.% content, using a mixture of nano silica and MWCNT particles into the adhesive led to a higher shear strength compared with single‐type reinforcement by each particle. Khayamdar and Khoramishad 33 found that the hybrid incorporation of MWCNTs and aluminum fibers led to greatest enhancements in static strength of adhesive joints. In a study performed by Zamani et al, 34 the influence of separate and mixed addition of nano silica and GNP particles into an epoxy adhesive was investigated on the static strength, fatigue behavior, and fatigue crack initiation life (CIL).…”

“…As mentioned above, limited research studies have been performed on evaluating the mechanical behavior of bonded joints by hybrid insertion of nanoparticles 32–34 . Thus, it is important to study the scenario of hybrid nanoparticle reinforcement, including particles with different shapes and features, from the static and fatigue behavior aspects, and also from the microstructural point of view to reveal damage mechanisms.…”

As bonded components of engineering structures inevitably experience fatigue loading conditions during their service life, it is significant to find ways to enhance their endurance. Also, adding nanoparticles to the adhesive can be introduced as an approach to design more durable bonded joints. In this way, it is important to determine a nanoparticle dispersion method which can lead to the longest fatigue life. Accordingly, this paper aims to investigate the influence of various nanoparticle dispersion treatments on static and fatigue responses of aluminum‐to‐composite bonded joints under four‐point bending. For this purpose, four dispersion techniques of mechanical stirring, bath‐sonication, low‐power and high‐power probe‐sonication were used to disperse nanoparticles into the adhesive. Also, four specimen groups of neat (with no additive particles), graphene nano platelet (GNP)‐reinforced, nano silica‐reinforced, and hybrid‐reinforced (including GNP + nano silica) were prepared. Results indicated that, for the joints including GNPs, the longest fatigue life was achieved for the specimens prepared by low‐power sonication method, while for hybrid‐type reinforcements, using high‐power method led to the highest endurance. Moreover, for 0.5 and 1.0 wt.% of nano silica, the endurance of bath‐sonicated specimens was 12.77% and 9.28% longer than low and high‐power probe‐sonicated joints, respectively. Using the backface strain (BFS) measurement technique, the influence of dispersion methods was studied on extending the crack initiation life (CIL) of each joint group. It was revealed that, for 0.5 wt.% and 1.0 wt.% of nano silica, the CIL is independent of the dispersion method, while, for 1.5 wt.%, probe sonicated specimens had the longest CIL. The microstructural characterization of each dispersion method and major reinforcing mechanisms were interpreted by scanning electron microscopy (SEM). For future researches, using X‐ray tomography and health monitoring methods is recommended to detect size and location of damage for nanoparticle reinforced composite structures.

Carbon fiber-reinforced titanium matrix composites were prepared by powder metallurgy. Carbon fiber (CF) powder and titanium (Ti) powder are mixed, pressed, and then sintered at a high temperature of 1300–1500 °C. The morphology and conductivity of carbon fiber-reinforced titanium matrix (Ti-CF) composites were studied. When the temperature range of the Ti-CF composites was from 1300 to 1500 °C, the porosity and resistivity first decreased and then increased. When the sintering temperature was 1350 °C, the diffraction peak of the sample was the strongest, the porosity was the smallest (4.16%), and the resistivity was the smallest (2.7 MΩ·mm). CFs have a very good strengthening effect on titanium-based composite materials.

“…In addition, it was stated that the modulus of elasticity increased by 35% and the tensile strength increased by 44% with the GO nanoplatelets addition. In a study by Khayamdar et al, 18 the mechanical properties of the adhesive joints were investigated by adding aluminum fiber with different geometries and CNT into the adhesive. They concluded that the highest improvement in the strength of joints was achieved with a combination of CNT and aluminum fibers, and this value was 171% compared to the neat specimen.…”

In the presented study, the effect of hexagonal boron nitride and hexagonal boron carbide nanoparticles on the strength of adhesively bonded joints was investigated experimentally. Hexagonal boron nitride nanoparticles were functionalized using 3-(aminopropyl) triethoxysilane to improve adhesion and increase the interaction between epoxy and nanoparticles. Similarly, h-B4C nanoparticles were functionalized by using 3-(glycidyloxypropyl) trimethoxysilane. New structural nano adhesives were produced by reinforcing the functionalized nanoparticles into epoxy at different proportions (0.5 wt.%, 1.0 wt.%, 2 wt.%, 3.0 wt.%, 4.0 wt.%, and 5.0 wt.%). Two different epoxies with different viscosity values (MGS-LR285 and Araldite 2011) were used as adhesives, and aluminum alloy (AA2024-T3) was chosen as an adherend. Tensile test was carried out to determine the failure load of the adhesive joints, and the fracture surface morphology was examined after the test Additionally, Scanning electron microscopy and energy dispersion X-ray spectroscopy (SEM-EDS) analysis was performed to observe the distribution of boron nanoparticles in the adhesives. The experimental results showed that the reinforcement of hexagonal boron nitride and boron carbide nanoparticles to the adhesives increased the joint strength substantially depending on the reinforcement ratio and viscosity of the adhesives. The maximum increase in failure loads was achieved by adding 1 wt.% functionalized boron nitride to high viscosity Araldite 2011 adhesive and 2 wt.% to low viscosity MGS-LR285 adhesive, and the ratio of increase in failure loads is 31% and 63%, respectively. Moreover, by adding 2 wt.% functionalized boron carbide nanoparticles to the Araldite 2011 and MGS-LR285 adhesives, the strength of the joints increased by about 27% and 70%, respectively.
