In the present work, woven jute and banana eco-friendly fibers were used, to increase the adhesion with epoxy and the performance of their composites, woven jute/banana fibres were alkali treated and PLA coated. To study the effect of PLA coating on the mechanical properties like tensile, flexural, impact and water absorption behavior of fabricated jute/banana hybrid composite laminates. The untreated and treated jute/banana fibres were used consisted of alkali treatment and PLA coating to fabricate its polymer-based composites by hand lay-up technique keeping constant fibres content as 30 wt.%. The different hybrid composite laminates untreated (JB1), PLA coated (JB2), NaOH treated (JB3) and PLA coated and NaOH treated (JB4) are fabricated. The percentage of PLA and NaOH treatment used is 5 % respectively. The testing of laminates are carried out as per ASTM standards. The study shows that the percentage increase in tensile strength of PLA coated and NaOH treated specimen (JB4) compared to untreated specimen (JB1) is 20.56%. The NaOH treated and PLA coated hybrid composite structure (JB4) has 16.7% more flexural strength than untreated hybrid composite structure (JB1). Water absorption capacity of PLA coated and NaOH treated Jute/Banana fiber reinforced hybrid composite specimen (JB4) is decreases by 47.6% when compared with untreated hybrid composite specimen (JB1).
