Experimental Investigation Of Mechanical Properties Of Teff Natural Fiber And E- Glass Hybrid Composite

Abstract

Hybrid Polymer Matrix Composite Materials Have Significant Applications In Different Areas For Weight Reduction Of Automobile And Other House Hold Furniture And However Application In Structural Load Bearing Due To Their Mechanical Properties Were Less. Mechanical Properties Of Polymer Matrix Composites Were Make Them Less Applicability Which Needs More Research Study. The Thesis Was Aimed To Fabricate A Hybrid Composite From Natural Teff Straw Fiber And E-Glass. Experiments Were Conducted Out By Preparing A Sample Having Different Weight Composition Of Reinforcement And Developed Through Different Levels Of Process Parameter. The Effect Of Reinforcement And Process Parameter On Mechanical Properties Has Been Studied. Investigation And Optimization Of The Fabricated Parameters Of Fiber In Teff Fiber And E Glass Fiber By Using Taguchi??S Method Were Considered In This Thesis Work. In This Study, A Series Of Tests (Tensile Test, Flexural Test, Impact Test, Hardness Test, Compression Test) Have Been Conducted According To Astm D4762 To Optimize The Most Significant Factor Of Teff Fiber And E-Glass. To Know How The Experimental Parameters Affect Mechanical Properties, The Statistical Software Have Been Used To Calculate The Signal-To-Noise (S/N) Ratio Of Each Factor And Analysis Of Variance (Anova) Was Also Used To Determine The Participation Percentage And Optimum Level Of The Considered Factors On The New Classes Of Products. The Amount Of Reinforcement Was Varied From 20% To 40% In Matrix Of 60% To 80% Weight Percentage. Three Parameters (Fiber Content, Fiber Orientation And Fiber Treatment) With Three Levels (20%, 30%, 40% Reinforcement And 60%, 70%, 80% Matrix)Were Considered. Composite With 30wt% Reinforcement (15% Teff Fiber, 15% E Glass) In 70wt%Matrix Were Found To Possess Higher Tensile Strength = 33.03mpa At Sample Number 9 Among The Fabricated Hybrid Composite Specimens. While Flexural Strength Of 64.48mpa And The Higher Compression Strength Of 74.43mpa At Sample Number 2 Was Measured. The Maximum Impact Strength Of 127 Kj/M2 Was Noted. Finally, This Research Work Is Expected To Help All Industries And Researchers Working In This Area Of Focus..
