Surface Functionalization of Jute Fibers In The Presence Of Sodium Hydroxide and Graphene Oxide in the Preparation of Bio Composite

Abstract

Abstract The natural fibers (jute, bamboo, banana etc.) has high strength to weight ratios, inexpensiveness, low densities, good mechanical properties, environment friendly, ease of manufacturing and availability due to this properties natural fibers are now days vitally popular. Jute fibers have good mechanical properties. The interfacial strength (23.6%) and tensile strength (96%) of the coated jute fibers increases more than untreated jute fibers. The morphologies of treated and untreated jute fibers surface are display very different in the analysis of SEM. Which jute fibers are untreated that smooth and it contains hemicellulose, lignin and pectin and they are covered with lots of lump materials. Which are removed after functionalization of the jute fibers in the presence of NaOH. This work presented the improvement of the epoxy based composite with the functionalized jute fibers as filler used for increased the mechanical (tensile, flexural strength) properties of the composites. The flexural strength of the prepared composites increases from 259.9MPa to 325.5MPa and the flexural modulus increases from 16.7GPa to 21.5GPa in the prepared composites by using functionalized jute fibers in the comparison of untreated jute fibers composites. These jute fibers based composites very useful for the environment so it can reduce the synthetic fibers based composites.
