Fabrication and Characterization of Pineapple Leaf Fiber Reinforced Polyester Matrix Composite with Silicon Carbide and Coffee Husk

Abstract

Natural Fiber Composites Are Attractive Materials For Engineering And Industrial Applications Because Of Their, Light Weight, High Hardness, High Strength-To-Weight Ratio, Biodegradability And High Tensile Strength. The Weaker Fire Resistance And High Moisture Absorption Rate Are The Drawbacks Of Natural Fibers. However, Chemically Treating The Fiber And Adding Filler To The Composite Were Utilized To Reduce Water Absorption And Change The Surface Characteristics Of The Fiber. The Goal Of This Thesis Work Is To Use Hand Layup Techniques To Fabricate A Light Weight, Hard, And Strong Composite Of Pineapple Leaf Fiber Reinforced Polyester Matrix Composite With Silicon Carbide And Coffee Husk At Different Weight Compositions And Fiber Orientations. The Mechanical Properties Like Tensile Strength, Flexural Strength, Hardness, Impact Strength, And Physical Properties Like Water Absorption, Actual Density, Void Content With Morphological Analysis Of The Composite Were Studied. Minitab Software, Taguchi L9 And Grey Relational Analysis Was Used To Analyze The Statistical Study Of The Response Versus Parameter And Determine The Relevance Of Each Parameter. The Hybrid Composite Fabrication Was Used Meticulously Prepared For Physical, Mechanical, And Morphological Tests In Accordance With Astm Standards. The Results Revealed That Maximum Average Tensile, Flexural Strength, Hardness And Impact Strength Were 34.8 Mpa, 174.88 Mpa,40.6 Hv And 6j Respectively. The Was A Minimum Value Of 0.235%. The Minimum Values Of Water Absorption, Actual Density And Void Content Of Composite Were 0.235%, 1.169 G/Cm3 And 0.59% Respectively. The Results Indicate That Coffee Husk And Silicon Carbide Powder Used As Filler Materials And Pineapple Leaf Fiber As Reinforcements In This Study Improved The Mechanical Properties Of The Developed Composite. From Grey Relational Analysis, The Optimum Values For Multi-Response Characteristics Has Been Obtained At A2b1c3d2.Fabricated Composite Used In Automotive Application Such As Bicycle Mud Guard And Engine Under Cover.
