“…The main assumption for this work is that there are perfect bonds between all the parts of the composites. The relation between the continuum models of CNT and graphene are presented [41,42]. One of the assumptions that will be considered in the micromechanics is that the reinforcement distribution is uniform.…”

The mechanical properties of carbon fiber-reinforced epoxy composites were identified by adding carbon-based nano-reinforcements, such as multi-wall carbon nanotubes (CNTs) and graphene platelets (GP), into the epoxy matrix by conducting suitable experiments. The main focus of this study is to compare the tensile modulus, tensile strength, flexural modulus, flexural strength, and thermal conductivity of carbon fiber-reinforced epoxy composites with nanoparticle reinforcement. The results revealed that adding CNTs and GP nanoparticles improved the mechanical properties compared to a pure carbon fiber-reinforced plastic composite. However, compared to CNTs, the GP's addition has increased the mechanical properties of the CFRP composite. In addition, scanning electron microscopy (SEM) images were presented to explore the microstructural characterization of carbon fiber-reinforced nanoparticle-reinforced composites. Further, using numerical studies, the transverse modulus, major and minor Poisson’s ratio of the carbon fibre reinforced with CNT and GP particle reinforcement were estimated. The current study is applied to the efficient design of nanoparticle reinforced carbon fibre reinforced composites.

“…Last but not least, the presence of vanadium, having high hardness and graphene, having high strength and stiffness have increased the hardness of the composites. 68,82 However, the effect of the high content of graphene content on the hardness of Cu-G hybrid composite is yet uncertain as so far not much work has been performed in this direction.…”

Copper (Cu) composites hybridized with nano-sized reinforcing material are gathering attraction in such fields as automobile, aerospace, and power transmission due to their higher strength. Unlike conventional reinforcing materials, extraordinary mechanical properties and high electrical and thermal conductivity make nanomaterials highly useful reinforcement materials to improve the properties of pristine metals. Over the last two decades, several studies have been conducted to determine the effect of distinctive 2D nanomaterials, such as silicon carbide, aluminium oxide, copper nanotube, and graphene as reinforcement on properties of metal matrices. This study comprehensively reviews the effect of hybrid reinforcements on the mechanical properties of Cu composites having graphene as one of the reinforcements. Also, the contribution of these reinforced nanomaterials composition and their dispersion in the pure Cu matrices have also been explained in detail. In comparison with Cu composites fabricated with a single 2D reinforcement material, composites incorporating hybrid nano reinforcement, exhibit better mechanical behaviour. Additionally, the improvement in mechanical strength would enhance their capability to withstand altering thermal and surrounding environmental conditions.

“…As an alternative, nanoscale fillers like carbon derivatives, − nano-clay, nano-silica, alumina, etc., have also been used to reinforce epoxy polymers. Comparatively, the nano-fillers, like carbon nanotubes (CNTs), graphene, graphene oxide, etc., significantly enhance the stiffness of nanocomposites due to the improved interactions at the polymer–filler interface. , The epoxy can be effectively reinforced with nano-fillers yielding composites with improved performance. Due to the high aspect ratio, the requirement of nano-fillers per unit weight is very less compared to that of the micro-fillers.…”

Epoxies, their derivatives, and composites, due to superior specific strength, are preferred for many potential applications in the field of automobiles, aircraft, bonding of structures, protective coatings, water filtration, etc. As structural members in automobiles and aircraft, the epoxy-based components are exposed to various static/dynamic mechanical loading conditions during their service life. The interfacial interactions, between the matrix and reinforcement, greatly affect the final properties of the composites. The present study demonstrates that the solvent used for the preparation of the composite can also contribute toward interfacial interactions. Present research systematically finds out a suitable solvent (acetone) and reinforcement type [multi-walled carbon nanotube (CNT)] for epoxy [bisphenol-A (BPA)] nanocomposites. Dynamic and static strengths of the as-prepared epoxy–CNT nanocomposites were carefully investigated. Well dispersed CNTs in acetone were mixed with an ester of BPA under constant magnetic stirring conditions. Samples of tablet shape were prepared for testing static and dynamic performance of the composite using a nano-indentation technique. Considerable enhancement by 55 and 22% in the static elastic modulus and hardness of BPA–CNT composites, respectively, was observed (compared with that of pristine BPA). The storage modulus and tan-delta of the nanocomposites were also improved by 14 and 46%, respectively. Improved static and dynamic performance, reported in this work, significantly enhances the scope of utilization of BPA–CNT-based nanocomposites under severe static and dynamic loading conditions simultaneously. Static and dynamical analysis of CNT-reinforced epoxy provides more realistic understanding of the mechanical performance of the nanocomposite. Density functional theory (using QuantumATK software) simulations were performed to investigate and identify the alterations in the atomic morphology of CNTs during interfacial interaction with the acetone molecule and epoxy matrix. The calculations predicted that CNTs with mild defects as compared to pristine CNTs were better suited for synthesis of the nanocomposite and also assisted in a homogeneous distribution of CNTs in BPA without aggregation (with acetone as the solvent). Furthermore, structural changes in CNTs after treatment with BPA and the curing agent and the role of defects are studied in detail.
