The result showed that the density increased by 2.18%, decreased by 4.1 % and increased by 10.33%, whereas porosity increased from 0.37 % to 1.43 %, from 0.37 % to 2.27 % and from 0.37 % to 1.64% as the weight % of reinforcement particles increased from 0 to 12 % in case of silicon nitride, graphite and ball milled (silicon nitride + graphite) reinforced composites respectively. © 2014 The Authors.

Introduction Aluminium metal can be used as a key matrix element in the production of composite materials because of its light weight and these contrived composite are named as Aluminium Matrix composites (AMCs). There is inflated petition for a low cost with nimble weight and a sturdier and energy useable material in the aircraft, space, defense and automotive applications due to technology evolution. AMCs presented usage in the manufacturing of these parts [1-2]. Meanwhile from last forty to fifty years there is pervasive research and innovatory evolvement in the field of composite materials and most of the investigator exasperated to strengthen conventional metal and their alloy with ceramic phase to increase their properties in the very past few years or in the recent time [3] and these AMCs made having particular and stout potential in the area of engineering and non-engineering components [4]. * Corresponding author.
