Abstract This paper summarises the research work carried out in the field of carbon nanotube (CNT) aluminium matrix composites which are being investigated for their use in automobile and aerospace industries because of their low density and high specific strength .This paper addresses a brief description on fabrication techniques particularly ball milling which aims to achieve homogeneous distribution of CNT in the matrix. Also, the effect of ball milling parameters on CNT dispersion and the effect of CNT reinforcement on mechanical properties-toughness and hardness and friction and wear behaviour has been critically reviewed as well. The analysis presented here would be instrumental in the future design of high strength CNT/Al matrix composites. © 2014 The Authors. Elsevier Ltd. All rights reserved.

Introduction: In the past few decades, the research in material science has become focused on composite materials as they can be developed into light weight, environment friendly, and high performance appliances. At least two chemically distinct materials that are separated by a clear interface constitute a composite. As compared to conventional materials, composites have high stiffness and strength [1]. In the past few decades, ongoing research in CNTs as * Corresponding author. Tel.:9654364948 E-mail address: qasimmurtaza@dce.ac.in © 2015 Elsevier Ltd. All rights reserved.
