Abstract—Composites in today’s world play an important role as they are being used as replacements for conventional materials. Aluminum is most widely used as base matrix in a composite because of its low density high strength property . To maintain similar density range along with improvement in material strength, Beryl (Beryllium aluminum cylcosilicate) is used as the reinforcement . The combination of aluminum and beryl enhances the material properties of aluminum without any drastic increase in the total mass density of the composite. Stircasting technique has been employed to cast Al-Beryl MMC by varying beryl’s percentage each time. Friction, wear, hardness and tensile tests has been carried out in this work. Taguchi method is performed on the results obtained from the experiments .Optimization of parameters using S/N ratio and ANOVA is carried out.
Index Terms—Al-6061, Beryl, MMC, Taguchi, Tribology.
I. INTRODUCTION
Composites are combination of two or more than two materials most likely to have different properties. A composite has a base matrix and reinforcement(s) as its constituents. Majority of the composite is composed of the base material. Addition of reinforcement improves the performance of the material. Some of the benefits that composites have over conventional materials are High strength, Light weight, Corrosion resistance, High impact strength, Flexibility, Durability etc. Among different types of composites available MMC’s(Metal Matrix Composites) generate wide interests in the research field. MMC’s are widely known for their stiffness, High strength, Fracture toughness. They can withstand corrosion at higher temperature. These composites are stable even at elevated temperatures. Aluminum, Titanium, magnesium are popular choices as the matrix base. In this project Aluminum 6061 has been considered as the base matrix. Aluminum metal matrix composites are known for their low density and high specific mechanical properties. The strength and wear resistance is equal to that of cast iron.
