This paper basically surveys the continuing development in metal framework composites bolstered with carbon nanotubes (CNTs). Aluminum metal framework composites fortified with CNTs have become extra significance because of their low thickness, remarkable mechanical and tribological homes. CNT bolstered Al steel lattice composites commonly preferred composites in easy applications. it's miles clean from the writing that no matter the truth that extra extension for the nanocomposites exists however troubles in handling upsets the improvement in Al/CNT composites. This audit paper illuminates part of the handling strategies with the purpose that future investigates might also moreover spark off first rate results inside the manufacture of awesome composite materials.

Recent developments in the field of carbon nanotube (CNT) have attracted attentions on a new development of aluminum matrix composite (AMC). Homogenous dispersion and interfacial bonding of CNT/metal matrix are the two main problems yet to have sound solutions. In general, to ensure uniform dispersion, the overall process can be divided into three steps: preprocessing, mixing and post processing. This paper summarizes previous works on solid and liquid processing techniques which some are more successful than others by looking at the improvement of the composite tensile strengths. On the other hand the interfacial bonding depends on the existance of Al4C3 phase and physical conditions of CNT. Both elements must be controlled for the optimized results. The review presented here would be used as references in the future works to fabricate higher strength CNT/aluminum composites.

“…A low melting point for Sn in the composition causes liquid phase sintering of aluminum composites [21]. The powder metallurgy process operates at a temperature of 75 to 90% of the melting point of the matrix material [22]. In powder metallurgy, there are various fabrication techniques such as hot pressing [23], spark plasma sintering [24], cold pressing, and sintering [25].…”

Carbon nanotubes (CNTs) have shown tremendous progress during the past two decades due to their extraordinary properties. With CNTs added as an alloying element, various engineering materials exhibit better mechanical properties. Multi-walled carbon nanotubes (MWCNT) were synthesized in-house by chemical vapor deposition process. Carbon nanotube-reinforced aluminum composites were prepared by cold pressing (or compaction) and sintering using different fractions (0.5, 1.0, 1.5, and 2.0 weight percent) of MWCNTs. The Al-CNT composites consists of tin (Sn) at 1.0 wt. % in each composition. Tin promotes the sintering of aluminum matrix composite. The effect of CNT on the density, hardness, and wear behavior of the composites were studied. Wear tests were performed to determine friction and wear under dry, wet, and hot conditions under varying loads from 5 N to 20 N. X-ray diffraction, Raman spectroscopy, scanning electron microscopy, and transmission electron microscopy techniques were used for the characterization. This investigation shows that increased CNT content significantly improves the hardness and wear resistance of the composites. The friction and wear were found to increase with operating temperature. A significant reduction in coefficient of friction and wear rate was observed with the application of oil during the wear test.
