Application of composite materials are increasing remarkably because of its much advantage compared to base matrix alloys properties like reduced weight, increasing strength, increasing wear resistance capacity etc. Reinforcement particles play a very important role for preparing metal matrix composite and ultimately improve its properties. In the present experiment, Al6063 designated aluminium alloy is used as matrix material and borosilicate glass powder is used as reinforcement. Specimens are prepared by stir casting method. Borosilicate glass is collected from scientific laboratory scrap to support disposal as well as recycle of the waste glass materials. In order to reduce the experimental run, the design of experiment is incorporated as per Taguchi’s L9 orthogonal array. It is observed that glass reinforcement in Al6063 aluminium alloy is compatible to form metal matrix composite. Secondly, ultimate tensile strength of the composite increases in selected combination of grain size and weight ratio of the borosilicate glass powder to the metal matrix.
