In this study, woven jute fibers were subjected to an eco-friendly NaOH treatment and polylactic acid (PLA) coating to improve adhesion with epoxy resins and improve composite performance. The treated and coated jute fiber reinforced epoxy composites were prepared by hand layup technique such that the fiber content in each composite was kept constant at 40 wt%. The dynamic mechanical properties of the prepared composites were determined using dynamic mechanical analysis (DMA) based on storage modulus (E'), loss modulus (E"), and damping coefficient (Tan ) Tests are performed in three-point bending mode Experimental results show that NaOH-treated and PLA-coated jute composites perform best compared to untreated jute fiber reinforced composites indicates that Composites reinforced with NaOH-treated and PLA-coated jute fibers exhibited the highest values for storage modulus, loss modulus, and glass transition temperature.
