“…Many surface modifications have been reported to improve the interfacial adhesion between the composite constituents, [15,[17][18][19] with alkali treatment being one of the simplest and most effective methods. [20] Alkali treatment using sodium hydroxide (NaOH) solutions is one of the most common methods for treating bamboo fiber bundles [21] and can enhance not only the interfacial adhesion between natural fibers and polymeric matrices but also the mechanical, physical and thermal properties of the fibers. [22,23] This treatment promotes solubilization of hemicellulose and lignin [21,24] and separates the fibers into fibrils, which increases the available surface area of the fiber to be "wet" by the polymer matrix enhancing the interfacial bonding.…”

Bamboo fibers (BFs) have high mechanical properties and are candidate reinforcement for epoxy matrix composites. However, to improve performance, good fiber‐matrix interaction is required. In this work, unidirectional long BF reinforced epoxy composites at fiber volume content of 22%, 40%, and 50% were made by compression molding. The 40 v% untreated BF reinforced composites exhibited 107% and 439% increase for flexural strength and modulus, respectively, compared to neat epoxy. Sodium hydroxide (NaOH) treatment was used to modify the surface of the BFs, and then the NaOH modified BFs were coated with graphene oxide (GO). The 40 v% NaOH modified BF composites showed an improvement from 259.9 to 327.5 MPa for flexural strength and from 16.7 to 21.5 GPa for flexural modulus, compared to 40 v% untreated BF composites. Slight improvement in properties up to 334.6 MPa for flexural strength and up to 23.8 GPa for flexural modulus was achieved for composites made of 40 v% NaOH/GO modified BF. Surface modification of BF after the NaOH and NaOH/GO treatment was confirmed by X‐ray photoelectron spectroscopy and by scanning electron microscopy, which showed differences on the fiber surface morphology and on the composite fracture surface. This BF surface modification approach with GO has potential to impart other properties beyond mechanical to produce multifunctional composite and lead to the use of sustainable plant fibers as alternatives to synthetic fibers.

“…Due to the removal of surface materials by the treatment of the jute fibers jute fibers surface become rougher which are very important for mechanical properties of the composite interlocking between jute fibers and epoxy resin. And also improved jute fibers adhesive properties [20]. Excessive concentration of NaOH treatment of fibers can decrease the fiber strength [21].…”

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.
