Experimental investigation on physical mechanical and acoustical behavior of SISAL PALM SISAL JUTE and PALM JUTE Fiber Reinforced Hybrid Epoxy Composites

Abstract

Natural fiber composites play a major role as a substitute to plastics due newlineto their low cost, higher strength, ease of availability, better stiffness, and eco newlinefriendly and biodegradable. Among different natural composites, the hybrid newlinenatural fiber composites have been found in various fields of applications newlinesuch as aerospace, automotive industry, marine field and building structures. newlineIn this study, the fibers are extracted from leaves of sisal, bast (skin) of newlinejute plants and bract on a palmyra tree and the fibers are treated with NaOH newlinealkali solution. An attempt is made to fabricate three hybrid natural fiber newlinecomposites using natural fibers like Sisal(S), Palm(P), Jute(J) and Epoxy(E) newlineresin in different weight ratios (Sample A, B and C) by compression molding newlinemethod and their physical (thickness, density and thermal conductivity), newlinemechanical(tensile, flexural, impact, moisture absorption) and acoustical newlineproperties are investigated experimentally. The samples are prepared as per newlineASTM standards to explore their physical, mechanical and acoustical newlineproperties. The tensile, flexural and impact tests are carried out on the above newlineprepared hybrid composite samples according to the ASTM D3039, ASTM D newline790 and ASTM D 256 standards. The moisture absorption, thermal newlineconductivity and sound absorption coefficient test using Impedance test tube newlineare observed according to ASTM D 570 and ASTM E1530 and ASTM E newline1050 standard respectively. newlineThe mechanical characteristics (Tensile, flexural and impact strength of newlinesisal/palm, sisal/jute and palm/jute hybrid epoxy composites with three newlinedifferent weight ratios (sample A, B and C) were characterised. Similarly, an newlineexperimental study on water absorption and thermal conductivity newlinecharacteristics of (sisal/palm, sisal/jute and palm/jute) were carried out. newline
