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.

“…Since their emergence, carbon nanotubes (CNTs) have been increasingly used for the fabrication of advanced composites as the ideal reinforcing agent owing to their rewarding mechanical properties such as fracture strain sustaining capability, light weight, large elastic strain, and high elastic modulus [18][19][20]. However, CNT-containing composite applications are accompanied by the high complexity because several factors such as the nanotube/matrix bonding, nanotubes dispersion, reinforcement aspect ratio, surface reactivity, and densification of bulk composites should be controlled [8,[21][22][23]. In this research, the Ni-Cu/CNT composite coating is deposited on the st37 substrate, and its mechanical and corrosion behaviors as well as the inhibitory property of CNT on the coating surface were evaluated.…”

St37 steel has been used in various industries due to its abundance and low cost. However, the high corrosion rate of steel in acidic environments is one of the limiting factors for its application. In this study, Ni-Cu composite coating reinforced with CNTs was applied on the st37 steel substrate. The extract of the Sarang Semut plant was added to the coating as inhibitory particles and the electrochemical behavior of the coating was investigated. The X-ray diffraction test was performed for phase analysis. Hardness, wear, and dynamic potential polarization tests were performed. Results showed that the presence of CNT particles improved the hardness, tribological performance, and electrochemical behavior of the coating. Also, the presence of Sarang Semut particles acted as a barrier and protected the surface of st37 steel from corrosion. It should be noted that these particles affected the kinetics and thermodynamics of corrosion reactions and were not involved in the reactions.

“…Recently, many studies on using CNTs for MMCs (i.e. Al, Cu, Mg and Ni) have been published which demonstrated that CNTs could enhance the mechanical, thermal and electrical properties of the composites [6][7][8][9][10][11][12][13][14][15][16][17][18]. Among them, CNT/Cu composite is one of the most important composites due to their high potential applications in the electronics and electrical industries [19][20][21][22].…”

Multi-walled carbon nanotube (MWCNT)/Cu composite containing 0.5 vol% MWCNTs were prepared by a high energy ball milling followed by conventional sintering and finally cold rolling. Microstructure studies showed that MWCNTs were uniformly dispersed and implanted inside the Cu matrix. The MWCNT/Cu composites showed an improvement in hardness and tensile strength up to 37% and 44% respectively compared to those of pure Cu. The enhancement is attributed to the uniform dispersion and strengthening due to the addition of MWCNTs. The yield strength of the composite has been quantified by several strengthening mechanisms including grain boundary strengthening, dislocation strengthening, Orowan strengthening and load transfer. The calculated results indicated that the load transfer strengthening has the largest contribution to the yield strength of the composite which implied the key role of the interfacial bond strength between MWCNTs and Cu matrix on the strengthening behaviors. The friction coefficient and specific wear rate of the composites were reduced with the addition of MWCNT content due to the self-lubrication effect of CNTs and high mechanical properties.
