“…Although there was grain refinement in the metal matrix, the lack of interaction between the metal matrix and reinforcement was reported by this method. Alekseev et al investigated the effect of CNTs on the mechanical properties of cast Al, grade A5. Significant improvement in the mechanical properties was observed with a small addition of CNT reinforcements by casting.…”

Herein, the investigations conducted in the area of aluminum (Al) matrix composites reinforced with carbon nanotubes (CNTs) are presented. The application of CNT reinforcement in Al alloys is driven by its exceptional chemical and mechanical properties. The critical issues in the processing techniques, challenges in the interfacial mechanisms between the Al matrix and CNTs, and strengthening effects due to the presence of reinforcements are reviewed. The mechanical properties of CNT/Al composites are found to be effectively enhanced with an addition of CNTs even at a small amount. The extent of strength improvements depends mainly on the dispersion of CNTs in the matrix and interfacial bonding between the matrix and CNTs. Limited theoretical modeling can predict the properties of CNT/Al composites to some extent, but without considering the detailed processing parameters. Based on the gaps identified here, future research directions are suggested, including the relationships between the processing parameters and micro-and nanostructures, and multiscale mechanical modeling and simulation, aiming to further understand the strengthening mechanisms and develop advanced CNT-reinforced Al and other metal composites for critical engineering applications.

The paper presents results of studying mechanical properties of polymer composites depending on types of filler particles (granular - carbon black, nanodiamonds; layered - graphene plates; fibrous - single-walled nanotubes). These nanofillers differ greatly from each other in their structure and geometry. A significant difference in behavior of nanocomposites was revealed even with little introduction of particles into the elastomer. The highest level of reinforcement of the matrix was obtained when single-wall nanotubes and detonation nanodiamonds were used as fillers. The viscoelastic properties and the Mullins softening effect [1-4] were investigated in experiments performed with material samples subjected to complex uniaxial cyclic deformation. In these experiments, the amplitude of deformations was changed step by step; and at each step a time delay was specified to complete rearrangement processes of the material structure. It was found that a pronounced softening effect after the first cycle of deformation and significant hysteresis losses occur in the material filled with single-walled nanotubes. These characteristics are insignificant for the rest of nanocomposites until elongation increases twofold. In accordance with the obtained results, a new version of the mathematical model to describe properties of the viscoelastic polymer materials was proposed. The constants of the constitutive relations were calculated for each material; the theoretical and experimental load curves were compared. As a result, the introduced model is able to describe the behavior of elastomeric nanocomposites with a high accuracy. Moreover, this model is relatively easy to use, suitable for a wide range of strain rates and stretch ratios and does not require the entire history of deformation as needed for integral models of viscoelasticity.
