A Review on CNT Reinforced Aluminium and Magnesium Matrix Composites

Abstract

Carbon Nanotubes (CNT) are one allotropic form of carbon, which have some unique characteristics that make them a suitable reinforcing agent in various types of composites. CNT reinforced composites are gaining more attention in recent days. Reinforcing with CNT leads to increase in strength without considerable increase in weight. Many metal matrix composites (MMCs) with base metals like aluminium, magnesium, copper, nickel etc., and polymer matrix composites (PMCs) have been fabricated and experimented with CNT as one of their reinforcing agents and corresponding results have been recorded. This paper reviews a few of these recordings on Al and Mg MMCs and also some future development in this field.

Comparison of the surface morphologies of ceramic reinforced metal matrix composite cams after wear tests under dry and wet conditions

“…have the potential for restricting fuel consumption and wearing of the cams, comprehensive research is yet to be performed. 18,19…”

“…have the potential for restricting fuel consumption and wearing of the cams, comprehensive research is yet to be performed. 18,19 Dayanc et al 15 investigated the influence of cathodic electrolytic plasma hardening (CEPH) on the C45 steel, gray cast iron and nodular cast iron camshafts. The surface of the host materials was hardened, which improved the wear resistance (5-6 times) under dry conditions.…”

Analysis of shielding effectiveness and mechanical properties of metal matrix composite AL6061 reinforced with Al2O3 and fly ash for oblique incidence of EM wave

“…have different physical models (Gizatullin et al , 2016). Al6O61 was introduced as an alternative to FRP, which has adequate properties like low density, specific corrosion resistance, high strength and good electrical properties (Ramnath et al , 2014).…”

Investigations on wire electric discharge machining of hybrid nano metal matrix composites (AA6061/SiC/B 4 C) for industry need based multi-response optimization

“…The widespread utilization of aluminium alloy (AA) based composite materials in manufacturing aviation and automobile structures are well recognized today. This is because of some predominant properties of these materials like high strength to weight ratios, incredible low temperature application, excellent corrosion resistance and good machinability index [1]. Aluminium based metal matrix composites (MMCs) have found numerous applications in the fields of automobiles, aviation, defense and nuclear power stations [2].…”

“…Researchers for machining these MMCs [1,4,6] have used various non-traditional machining techniques like electric discharge machining (EDM), electro chemical machining (ECM), laser beam machining (LBM) and abrasive water jet machining (AWJM). These machining techniques are selected based on economic viability, performance and efficiency of the methods.…”
