In the present work, woven jute fibers were subjected to environmentally friendly NaOH treatment and Poly Lactic Acid (PLA) coating in order to improve the adhesion with epoxy thereby improving the performances of their composites. Treated and coated jute fibres reinforced epoxy composites were prepared by hand lay-up technique keeping constant 40 wt.% of fibres content in each composite. The dynamic mechanical properties of prepared composite is determined in terms of storage modulus (E'), loss modulus (E"), and damping factor (Tan ) were obtained utilizing Dynamic Mechanical Analysis (DMA). The test is carried out using three point bending mode at 1 Hz frequency. The outcomes from the experimental results suggested to that NaOH treated and PLA coated jute composite exhibited the best performance as compared to untreated jute fiber reinforced composites. The highest values of storage and loss modulus, and glass transition temperature was offered by the composite reinforced by NaOH treated and PLA coated jute fibres.
