Fabrication, Testing, and Adhesive Bonding of Hybrid Polymer Matrix Composite Reinforced with Sisal Fiber, E-Glass, and SiC

Abstract

Polymer-Based Composite Materials Are Widely Used In Various Industries. CompositeJoining Using The Adhesive Joining Method Is An Increasing Concern In Various IndustriesWorldwide. The Main Problems Of Natural Fiber-Based Polymer Matrix Composites Are TheirLower Mechanical Properties Than Other Materials. In Other Ways, Composite Joining Was Challenging While Controlling The Adhesive Joining Parameters. This Thesis Aims To DevelopA Hybrid Composite From Polyester Resin-Sisal Fiber-E-Glass-Sic And Study The AdhesiveJoining Of This Composite. The Composite Tensile, Flexural, Impact, And Hardness PropertiesWere Analyzed As Per Astm Standards. The Wt.% Of The Sisal And E-Glass Fibers (0,10 And15) Were Optimized Using Taguchi-Based Gra. Further, Morphology Analysis Was Analyzed.The Parameters Influencing The Adhesive Joint Performance, Such As Joint Configuration (Slj,Scj, And Stj), Sic Filler (0, 1.5, And 3)Wt.%., And Overlap Lengths Of (20, 25, And 30)Mm,Were Analyzed And Optimized Using Taguchi-Based Gra. The Results From The Fabricated Composite Show That 42.13 Mpa, 185.56 Mpa, 24.75 J, And 97.93 Hv Of Tensile, Flexural,Impact, And Vickers Hardness Were Achieved Respectively. The 15 Wt. % Of Both Sisal And E-Glass Fibers Have More Effects On The Mechanical Properties Of The Composite. The Results OfComposite Adhesive Joining Reveal That, A Maximum Of 32.63 And 90.15 Mpa Of Joint TensileAnd Flexural Strengths Were Achieved. Based On The Taguchi-Based Gra, An Optimum JoiningParameter Of Scj, 3 Wt.% Sic Filler And Overlap Length Of 30mm Were Obtained And HadMore Influence On The Joint Strength Of The Composite. This Research Work Is Expected To HelpDifferent Industries, Governments, And Researchers Working On Developing Composite AndComposite Adhesive Joining Areas.
