dc.description.abstractIn The Present Study, Hybrid Composite Materials Are Replacing Heavy Materials Such As Metals Due To Their Lightweight Advantages. The Primary Purpose Of This Study Was To Characterize A Hybrid Composite Reinforced With Al2o3/Sic, Bagasse Fibers And Polyester For Light Weight Applications. Hand Lay-Up Technique Was Used For Sample Preparation Of The Composite. Taguchi L9 Orthogonal Array Was Utilized For The Design Of The Experiment. This Experiment Was Conducted Using A Mass Balance, Specimen Cutter, Utm, Vicker Hardness Testing Machine, Impact Testing Machine, Drilling Machine, And Scanning Electron Microscope. The Specimens Were Prepared According To The Astm Standard For Each Test. The Properties Like Tensile Strength, Flexural Strength, Hardness, Impact Strength, And Water Absorption Test Were Studied. Actual Density, Void Content, Morphological Analysis And Machinability Tests Of The Composite Were Also Studied. Optimizations Of Parameters Were Done By Using The Taguchi Method And Grey Relational Analysis. The Results Revealed ThatMaximum Tensile And Flexural Strength Were 39.9 And 56.1 Mpa Respectively. Hardness And Impact Strength Were 75.05 Hv And 14 J Respectively. The Water Absorption Was A Minimum Value Of 0.250%. The Minimum Values Of Actual Density And Void Content Of Composite Were 1.252 G/Cm3And 0.8% Respectively. The Results Indicate That Al2o3 And Sic Powder Used As Filler Materials In This Study Improved The Mechanical Properties Of The Developed Hybrid Composite. Water Absorption, Actual Density, And Void Content Of The Composite Were Increased As Al2o3, Bagasse Fibers And Sic Wt.% Increased. From Grey Relational Analysis, The Optimum Levels Were A1b1c2 Which Means 6 Wt.% Of Alumina, 10Wt.% Of Bagasse Fibers And 8 Wt.% Of Silicon Carbide. At These Levels, All The Mechanical And Physical Properties Of The Hybrid Composite Were Optimum. Smooth Surface Finishing Was Observed For Drilled Surface And Less Amount Of Cracking Was Observed At The Opposite Side Of The Drilled Surface. The Results Help Higher Institutes For Research, Automotive Companies, Manufacturing Companies, Construction Sectors And Government To Conduct On How To Utilize This Abundant Waste Of Bagasse Fibers Resource.en_US
