Abstract: Natural fibre composites are of extensive in demand owing to ecofriendly attributes of natural fibres such as high specific strength and stiffness, renewability, biodegradability, less energy consumption and low CO₂ emission. In the current research, a novel Himalayan natural fibres i.e., Eriphorium-comosum (hairy cottongrass) is introduced as a reinforcing fibre to polyester resin. The physico-tribo-mechanical properties of the hand-layup fabricated polyester composites were evaluated for different sizes (15, 30, 45, 60 mm) and weight percent (3, 6, 9%) loading of Eriphorium-comosum fibres. The properties are optimised by applying multi-criteria TOPSIS technique which demonstrates that the polyester composite reinforced at 3 wt.% loading of Eriphorium-comosum of size 45 mm exhibits the best overall physico-tribo-mechanical performance.
