Influence of textile properties and textile pattern on sisal reinforced Poly Vinyl Ester (Flex GR 200-60) composite.

This paper focuses on the effect of yarn diameter, the density of yarn, woven type, Gram per Square Metre (GSM) and weight fraction fibre on tensile, flexural and impact properties of weaved sisal composite. Various types of woven fabrics were prepared from sisal fibres, and these fabrics are used to prepare the composites of variable weight fraction (W_ff) as 20, 40, 50 and 60 percent by maintaining proper alignment of warp and weft direction. The tensile, flexural, and impact properties were found to increase with W_ff content in all types of woven pattern composites. Plain 1 (P1) shows better mechanical properties as compared to Plain 2 (P2) and Plain 3 (P3)-based composites, and this shows GSM has a higher significance on mechanical properties. Further, the influence of woven pattern was analysed and found that the plain woven exhibits better tensile strength, but the herringbone exhibits better flexural and impact strength. Scanning Electron Microscope evidenced that good interfacial bonding between fibre and matrix interface. [ABSTRACT FROM AUTHOR]
