The present work elaborates the ongoing work in banana fiber reinforced in bio plastic for the making of green and sustainable composite. Non-woven banana fiber was used as reinforcement in bio polymer known as poly lactic acid (PLA). The mat of non-woven banana fiber rinsed in the melt PLA was pressed against the moving hydraulic press in a specific die of compression moulding machine. Fiber loading in PLA resin was meticulously selected as 20, 25, 30, 35 and 40 % of the total composition. The results obtained for the prepared composites shows that significant improvement was observed in the mechanical properties such as tensile, impact and flexural strength till 35 % of banana fiber reinforcement. At 40 % reinforcement of banana fiber, the improvement in tensile, impact and flexural strength was marginal. Hardness value of prepared composites found to be decreased with the addition of banana fiber. Among all the reinforcing conditions, tensile strength was noticed as64 MPa (maximum), and highest flexural strength was found to be 49 MPa, both at 35 % loading of banana fiber. Impact energy was also observed to be highest among all at 35 % of banana fiber loading which is found to be 2.2 J. The addition of banana fiber in PLA results in lower onset temperature of PLA and early degradation of composite. The obtained results aresufficientfor the development of low-cost products used in daily basis such as basins, basket, kitchens, and toilet accessories. It may also beneficial to expedite the development of sustainable and durable composite. The development of banana-reinforced PLA composite would be beneficial in meeting the needs of environmental safety agencies at a lower cost.
