Ecosystem sustainability and conservation of waste natural fiber strengthen epoxy composites for lightweight applications

Abstract

AbstractIn recent days, the automobile, aerospace, and marine sectors are imposed to search the similar quality alternative material with desired mechanical and wear characteristics obtained by using natural fiber extracted from environmental wastes. The current investigational characteristics study focuses to increase the mechanical properties of composite by using NaOH‐treated natural fiber like jute and sisal bonded with epoxy resin via the wet filament technique. The four different positions of fibers like the jute‐sisal fiber were dipped with epoxy resin and waved as random (multi‐directional), 0° (unidirectional), 90° (bi‐directional), and interlock position. The developed natural fiber composites were subjected to tensile, impact, and flexural strength made by ASTM procedure. The composite prepared with interlock position showed higher tensile, impact, and flexural strength 49.51 ± 1.51 MPa, 12 ± 0.98 J, and 57.31 ± 1.98 MPa respectively and improved by 12%, 33.3%, and 10% as compared to random (multi‐directional) composite. So the developed composites were enhanced by the conservation of jute/sisal fiber bonded with epoxy as interlocking distribution is utilized for lightweight applications and the conservation of waste natural fiber retained the ecosystem sustainability.
