“…Enhanced compatibility was achieved at 3% filler loading for the modified and unmodified kenaf reinforced nanocomposite with equivalent tensile strength and tensile modulus of 68.65 ± 0.79 and 78.61 ± 1.02 MPa and 2.65 ± 0.06 and 2.87 ± 0.07 GPa, respectively. Chemical modification of the fibre surface has been reported to increase the tensile strength of reinforced natural fibre-based nanocomposite [ 49 ]. Beyond 3% filler loading poor dispersion and interfacial interaction could be atrributed to the decreased tensile strength in both unmodified and modified kenaf reinforced nanocomposite.…”

The use of chemical modification of cellulosic fibre is applied in order to increase the hydrophobicity, hence improving the compatibility between the fibre and matrix bonding. In this study, the effect of propionic anhydride modification of kenaf fibre was investigated to determine the role of bionanocarbon from oil palm shell agricultural wastes in the improvement of the functional properties of bionanocomposites. The vinyl esters reinforced with unmodified and propionic anhydride modified kenaf fibres bio nanocomposites were prepared using 0, 1, 3, 5 wt% of bio-nanocarbon. Characterisation of the fabricated bionanocomposite was carried out using FESEM, TEM, FT-IR and TGA to investigate the morphological analysis, surface properties, functional and thermal analyses, respectively. Mechanical performance of bionanocomposites was evaluated according to standard methods. The chemical modification of cellulosic fibre with the incorporation of bionanocarbon in the matrix exhibited high enhancement of the tensile, flexural, and impact strengths, for approximately 63.91%, 49.61% and 54.82%, respectively. The morphological, structural and functional analyses revealed that better compatibility of the modified fibre–matrix interaction was achieved at 3% bionanocarbon loading, which indicated improved properties of the bionanocomposite. The nanocomposites exhibited high degradation temperature which signified good thermal stability properties. The improved properties of the bionanocomposite were attributed to the effect of the surface modification and bionanocarbon enhancement of the fibre–matrix networks.

“…Kenaf also has the highest environmental impact, as accumulating carbon dioxide at a significantly high rate. 16,29 The word kenaf is of Persian origin explaining the plant having short day, warm season, and annually herbaceous plant with the average diameter of 67.6 µm. 30 Kenaf is a hard, strong, and tough plant with a fibrous stalk, resistant to insect damage and requires little to no pesticides.…”

“…Moreover, compared to solely alkaline treatment, dual alkaline-H 2 O 2 , and alkaline-NaClO 2 treatments were found to be more effective on improving the properties of kenaf fiber. In addition, Arumugam et al 16 reported that incorporation of silver nanoparticles (2 wt%) in the chemically treated kenaf fiber/UPE composites could potentially further improve the mechanical properties and reduce the water absorption properties of the composites, because the nanomaterial enhanced the interfacial interaction and resulted in better adhesion between the kenaf fiber and polymer matrix.…”

“…Therefore, the certain drawback of natural fibers/polymers composites is the incompatibility between the hydrophilic natural fibers and the hydrophobic thermoplastic matrices which leads to undesirable properties of the composites. 16,17 The polar nature of natural fibers results in high moisture sorption in natural fiber-based composites, leading to fiber swelling and voids in the fiber matrix interphase. Moisture, if not removed from natural fibers prior to compounding by drying, will result in a porous product.…”

“…In comparison to other fibers, kenaf is a very promising natural fiber. According to researchers, the kenaf fibers is nonabrasive during processing 16 and possess good mechanical and physical properties to be used in polymer composites as reinforcement, replacing glass fibers. 32,35,38 –41 It is worth noting that a single fiber of kenaf can have a tensile strength and modulus of 11.9 and 60 GPa, respectively.…”

Recently development of high-performance polymer composites made from natural resources in the various sectors is increasing tremendously due to the environmental issues and health hazard possessed by the synthetic fibers during disposal and manufacturing. Among the many different types of natural resources, kenaf fibers have been extensively investigated as an alternative reinforcement for polymer composites over the past few years due to their low cost, good mechanical properties, high specific strength, nonabrasive, eco-friendly, and biodegradability characteristics. Kenaf is regarded as an industrial crop in Malaysia and grown commercially in other parts of the world for different applications. It is certainly one of the important plants cultivated for natural fibers globally which has great potential to use as automotive and construction materials. In many research studies, kenaf fibers have been used as reinforcement in unsaturated polyester (UPE) which perfectly improved the features of the polyester resin. The tensile properties of kenaf fiber reinforced UPE are mainly influenced by the interfacial adhesion between the fibers and the polyester resin. Several chemical modifications are employed to improve the interfacial bonding between kenaf fibers and polyester, resulting in the enhancement of mechanical properties of the composites. Therefore, this paper explores and highlights of the previous studies around kenaf fiber reinforced UPE composites, in terms of processing methods, mechanical, water absorption, and morphological properties to provide a perfect source of literature for doing further research in this topic.
