Fabrication, Characterization And Evaluation Of Mechanical Properties Of Aluminium Hybrid Matrix Composite (Al6063/Sic-Bagasse Fly-Ash)

Abstract

The Number Of Engineering Application In Industry Demands Need Best Mechanical Properties Of Material Such As Aerospace, Automotive Industry, Automotive Components, Propeller And Manufacturing Turbine Blade. To Satisfy These Requirements, Mmcs Have Certain Superior Mechanical Properties, Namely Higher Transvers Strength And Stiffness, Greater Shear And Compressive Strengths And Better High Temperature Capabilities Than Other Polymeric And Ceramic Composites. The Fabrication, Microstructure Characteristics And Mechanical Behaviour Of Al-Mg-Si Alloy Matrix Composites Reinforced With Silicon Carbide (Sic) And Bagasse Fly-Ash Was Investigated In This Work. This Was Aimed At Assessing The Viability Of Developing High Performance Al Matrix Composites Using Low Cost Reinforcements From Industrial Waste Products. In Addition, The Fabrication And Experimental Investigation Of Mechanical Properties Of Aluminium Matrix (Al/Sic) Composite With And Without Addition Of Bagasse Fly Ash By Varying Wt. % Of Reinforcements Was Investigated. Bagasse Fly-Ash Particulates Added With 7.5, 10, And 12wt% Sic Were Utilized To Prepare 10 And 12wt% Of The Reinforcing Phase With Al-Mg-Si Alloy As Matrix Using Stir Casting Method. Chemical Composition Of Reinforcement, Weighted The Required Amount Of Matrix And Reinforcements, Powder Mixing, Stirring The Slurry At 500rpm Speed And 5-10 Minute Were The Parameters Used To Develop The Al/Sic-Bagasse Fly-Ash Hybrid Composite. Tensile Testing, Compression Strength Testing, Micro-Hardness Measurement And Optical Microscopy Were Used To Characterize The Composites Produced. The Results Showed That The Hardness Of The Hybrid Composites Increased Slightly With Increase In Bagasse Fly-Ash Content With A Maximum Increment Of 17% Observed For The Al6063-7.5% Sic-10% Bagasse Ash Composition (In Comparison With The Al-10 Wt% Sic-7.5 Fly-Ash Reinforced Composition). Tensile Strength Reduced Of Maximum Value Of 90mpa To 68 Mpa At 7.5 Sic- 7.5 Bagasse Ash Compositions, While The Compression Strength Maximum Improved From 295mpa To 380.1mpa. In Hybrid Composite Superior Properties Are Observed In Tensile Strength, Compression Strength, And Hardness Than Single Reinforced Al/Sic Mmc.
