“…For dispersing MWCNTs into the adhesive, the procedure proposed by Gholami el al. 23 was followed. MWCNTs were dispersed in the adhesive layer using mechanical stirring and ultra-sonication.…”

“…So the joints were placed in the fixture and were cured at room temperature (25 C) for 24 h. The procedure that is used for dispersing nanofillers in polymer is important as it can considerably influence the results. In this study, two procedures proposed in literature 20,23 were used for dispersing nanofillers and the one resulted in higher improvements in the mechanical behavior of nanocomposite adhesive joints was chosen. It should be noted that changing the dispersion procedure and settings can change the results.…”

The effect of the geometry of metallic fibers on the mechanical response of aluminum fiber-reinforced composite adhesive joints was studied experimentally. Moreover, a combination of multi-walled carbon nanotubes and aluminum fibers was used for reinforcing the composite adhesive joints. Different geometries for the aluminum fibers including straight, twisted and spring-shaped with different pitch lengths were considered. The results indicated that the composite adhesive joints reinforced with a combination of multi-walled carbon nanotubes and aluminum fibers experienced the highest improvement of 171% in the strength compared to the unreinforced specimen. It was found out that the aluminum fiber geometry can significantly influence the adhesive joint behavior. Incorporating the twisted aluminum fibers into the adhesive layer increased, while the spring-shaped fibers decreased the strength of the composite adhesive joints compared to the straight aluminum fibers. The fracture surfaces of the composite adhesive joints were analyzed using scanning electron microscope.

“…1,2 From economical perspective, some glass fiber and Kevlar fiber reinforced polymer composite (GFRP and KFRP) components are difficult to be replaced by CFRP in automobile, aviation, earth moving, industrial machineries, and marine applications. Alternatively, the secondary reinforcement of inorganic nanofillers, such as SiO 2 and CoFe 2 O 4, 3 SiO 2, 4,5 Al 2 O 3, 4-6 ATH, 4,5 MgO, 4,5 CaCO 3, 4,5 MgO, 4,5 g-C3N4, 5 TiO 2 and Al 2 O 3, 7 multi-walled carbon nanotubes 6,8,9 graphene oxide nanoplatelets, 8,9 BaTiO 3, 10 SiC, 6 and graphene-carbon nanotube 9 were added to GFRP and KFRP composites to increase their mechanical properties. Also, the retention of mechanical properties under hydrothermal condition can be improved by addition of nanofillers [11][12][13][14] in GFRP composites.…”

Quest to reduce challenges of high structural weight and cost of metallic components is increasing. It has led to their replacement with carbon and Kevlar fibers reinforced polymer (FRP) composites. These aforementioned problems can be further solved through hybridization of carbon/glass (CG) and Kevlar/glass (KG) fibers to reduce the manufacturing cost and materials usage, not at detriment of their properties. Also, investigation into their tensile properties, diffusivity, and service life is germane. Therefore, the present study focuses on influence of hybridization of CG and KG fibers on seawater diffusivity, service life, and tensile strengths of their composite systems, through hydrothermal aging. The hybrid composites were aged in seawater for 50, 150, and 300 days at temperatures of 20, 40, and 60 C. From the results obtained, it was evident that the maximum moisture absorption of both FRP hybrid composites occurred at 60 C in 300 days of hydrothermal aging. The maximum tensile strengths were obtained in unaged composite counterparts. Also, the aged FRP hybrid composites exhibited the lowest tensile strengths at 150 days. The retention of maximum tensile strengths of CG and KG FRP

In another work, Gholami et al 42 published an experimental study of the fracture behaviour of glass-epoxy nanocomposite adhesive joints reinforced by aligned multi-walled CNTs and graphene oxide nanoplatelets. Ashofteh and Khoramishad 43 studied the influence of adding multi-walled CNT and graphene oxide nanoplatelets on the detrimental effect of pre-ageing in hot deionised water on the creep behaviour of single lap adhesive joints experimentally and numerically.…”

In this article, we study the thermal conductivity coefficient of the polypropylene composite reinforced by graphene sheets. A hierarchical approach is used for the investigation, which is started by molecular dynamics simulation to evaluate the thermal conductivity coefficient of graphene sheets and continued by the finite element analysis to evaluate the thermal conductivity coefficient of graphene reinforced polypropylene at different temperatures. It is shown that inclusion of the graphene sheets can lead to increasing the thermal conductivity coefficient of the polypropylene, especially when the nanosheets are directed along the temperature difference. Moreover, the higher volume percentages of the graphene sheets in the polymer matrix enhance the thermal conductivity.
