ICMPC_2018 Investigation of mechanical properties of carbon nanotubes reinforced aluminium composite by metal injection molding Vilas G Dhore a,b , W S Rathod a , K N Patil b a Veermata Jijabai Technological Institute, Mumbai, 400019, India b K J Somaiya College of Engineering, Mumbai, 400077, India Abstract The work presents the metal injection molding (MIM) of carbon nanotubes reinforced aluminium matrix nanocomposite. The paraffin wax (PW), high density polyethylene (HDPE), stearic acid (SA) is used as a binder. Sintering of aluminium is a critical issue in injection molding. The new blind mold cavity sintering method is adopted to impart the strength in the MMC. The surface morphology is observed by the SEM. It is seen that aluminium particles uniformly welded and wide pores are visible in the MMC- Al product. Further the low temperature blind mold sintering helps to retain CNTs in the MMC-Al matrix. This imparts the higher hardness which is comparable with the aluminium alloy. The hardness tests carried out on sintered samples shows the results ranging from 42 to 73 BHN. The pores in these samples tested are in the ranges from 0.25μm to 1.0μm. © 2018 Elsevier Ltd. All rights reserved.

Introduction There is continuous demand of light weight material with better mechanical properties. Aluminium is second most commonly used metal after iron due to its low density and corrosion resistance characteristics. Modern engineering systems quest wide variety of material properties, which conventional metallic alloy does not achieve. Metal matrix composite (MMCs) are suitable to develop a custom made properties for wide range of engineering applications[1]. * Corresponding author. E-mail address: vilasdhore@somaiya.edu
