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.
