Abstract— Now a days the aluminium metal matrix composites are enormously used in application of aircraft wheel rim material, aerospace, transport application. In this present work to study the effort is made to enhance the tensile strength of AMCs by reinforcing, AA 2014 matrix with both B₄C(2%,4%,6%,8%) and short E-glass fiber (2%,4%,6%,8%) of varying Proportion by stir casting technique and hybrid composites are fabricated. The microstructure, hardness and ultimate tensile strength of the fabricated AMCs were analyzed. The SEM was studied to know the homogeneous dispersion of B₄C particles and Short E-glass fiber in the composite. In this present investigated has been done to study the effect of each process parameter such as composition (2%, 4%, 6%, 8%), stirring speed (300, 320, 340, and 360 rpm) and stirring temperature (700, 750, 800 and 850oC). Fabricated the different specimens of hybrid composite material using stir casting technique and each parameter has four levels, L16 orthogonal array used to made different specimen. The effect of this input response or input parameter on the output response or output parameters has been analyzed by using design of experiment by taguchi technique (MINITAB17). Based on the results obtained from tensile and hardness test of the hybrid composites it is observed that, the ultimate tensile increases as the increase in the amount of both B4Cand short E-glass fibers up to( 4% ) after that the addition of both B₄C and short E-glass fiber is not much changes in UTS. If the addition of both B₄C and short E-glass fiber increases thus hardness also gradually increases. The results are reveal that the composition, stirring speed, stirring temperature of hybrid composite material have a significantly effect on the ultimate tensile strength, hardness and ductility.

I. INTRODUCTION

A composite is a heterogeneous material having two or more distinct phases which combined at a macroscopic level to obtain improved performances such as high strength, high stiffness and low density [15].
