  • Abstract:
  • Natural lingnocellulosic hybrid fibers like sisal and jute are receiving notable research focus as environmentally sustainable reinforcements for polymer composites. This experimental study focuses on a comparative evaluation between untreated and NaOH-treated jute-sisal hybrid composites, fabricated through the hand lay-up technique using a hybrid ratio of 60% sisal and 40% jute fibres. To enhance the fibre matrix interfacial bonding, the fibres were subjected to sodium hydroxide (NaOH) surface treatment prior to composite preparation. Samples were prepared in accordance with ASTM standards and evaluated for tensile, flexural, and bond strength. Further analysis of bond behaviour was conducted using Nitobond and Nitowrap epoxy systems to compare their adhesive performance and interaction with the natural fibre composites. Experimental findings indicated that the alkali-treated composites possessed superior tensile and flexural performance, resulting from improved interfacial bonding and reduced fibre detachment. Among the adhesives tested, Nitowrap provided greater bond strength and lower slippage. Overall, the findings confirm that chemical surface modification and adhesive selection significantly enhance the mechanical and bonding performance of hybrid natural fibre composites (HNFRP).
