Characterization of new natural cellulosic fiber from Cissus quadrangularis root

• Novel natural Cissus quadrangularis root fiber was characterized in this work.
• Anatomical study, chemical, thermal and mechanical analysis were done.
• Comprehensive characterization reveals better result.
• Characterized fiber has the potentiality to replace the harmful artificial fiber.
• Available in plenty and has the potential for textile and green composite.

Fiber reinforced polymer composites are replacing many metallic structures due to its high specific strength and modulus. However commonly used man-made E-glass fibers are hazardous for health and carcinogenic by nature. Comprehensive characterization of Cissus quadrangularis root fiber such as anatomical study, chemical analysis, physical analysis, FTIR, XRD, SEM analysis and thermo gravimetric analysis are done. The results are very encouraging for its application in fiber industries, composite manufacturing, etc. Due to its light weight and the presence of high cellulose content (77.17%) with very little wax (0.14%) provide high specific strength and good bonding properties. The flaky honeycomb outer surface and low microfibril angle revealed through electron microscopy contributes for its high modulus. The thermo gravimetric analysis indicates better thermal stability of the fiber up to 230 °C, which is well within the polymerization process temperature.
