Carbon nanotubes (CNTs) are promising reinforcements for fabricating aluminum (Al) matrix composites with outstanding properties. The understanding of the consolidation process of CNT–Al composite powders plays a significant role in achieving high performances of bulk composites. In this study, an advanced consolidation technique of spark plasma sintering (SPS) was used to fabricate CNT–Al comp...

Aluminum Matrix composites (AMCs) are light weight, high-strength materials with potential application in areas such as automobile, aerospace, defence, engineering and other industries. AMCs are projected to significantly reduce the overall weight of the vehicles and aircraft while maintaining satisfactory structural strength. Reinforcement of micron or nano-sized range particles with aluminium...

Since the discovery of carbon nanotubes (CNTs), [ 1 ] scientists have intensively investigated their intrinsic characteristics and tried to explore their properties after combining them with other materials. [ 2–15 ] Due to the large aspect ratio and a generically uniform diameter, the inner cavity of a CNT has been used as a nano test tube, siphon, catalyst carrier, and so on. [ 4–8 ] Recently...

The main challenge in the production of metal matrix composites reinforced by carbon nanotubes (CNTs) is the development of a manufacturing process ensuring the dispersion of nanoparticles without damaging them, and the formation of a strong bond with the metallic matrix to achieve an effective load transfer, so that the maximum reinforcement effect of CNTs will be accomplished. This research f...

Carbon nanotubes (CNTs) have attracted much attention because of their unique structure and remarkable mechanical, electrical, thermal and chemical properties. In particular, it has been believed that CNTs are ideal fillers for polymers to enhance their mechanical properties. Numerous efforts have been devoted to the application of SWNTs and MWNTs to polymers for the last decade [1]. However, i...

One-dimensional carbon nanotubes (CNT), which are mechanically strong and flexible, enhance strength of the host metal matrix. However, the reduction of ductility is often a serious drawback. Here, we report significantly enhanced plastic flow strength, while preventing tensile ductility reduction, by uniformly dispersing CNTs inAlmatrix. Nanoscale plasticity and rupturing processes near CNTs w...

The effect of ionic surfactants and manufacturing methods on the separation and distribution of multi-wall carbon nanotubes (CNTs) in a silicone matrix are investigated. The CNTs are dispersed in an aqueous solution of the anionic surfactant dodecylbenzene sulfonic acid (DBSA), the cationic surfactant cetyltrimethylammonium bromide (CTAB), and in a DBSA/CTAB surfactant mixture. Four types of CN...

Ultraviolet waves, because of their short wavelength, have a high energy and considerable damaging effects on surfaces. Protection against ultraviolet radiations is one of the finishing treatments done on surfaces exposed to sunlight. The importance of this issue in relation to human health, due to complications such as skin burns and cancer, is doubled. Up t...

The ball milling of powders is a non-equilibrium technique (similar to rapid solidification processes) that can be used for production and structural modification of materials. Carbon nanotubes (CNTs) are relatively new materials with excellent combination of properties. They are one of the advanced reinforcement materials for engineering composites. Besides the polymer and ceramic matrices, in...
