“…Several methods have been used to produce kenaf fiber reinforced UPE composites. Among the common methods used are hand lay up with compression, [53][54][55] laminate with compression, [56][57][58] compression moulding, 59,60 vacuum bagging and vacuum infusion, 61,62 filament winding, 63,64 pultrusion, [65][66][67] and resin transfer molding. [68][69][70] Hand lay up method has become a common method since it can accommodate all types of kenaf fiber including nonwoven (mat, long fiber, short fiber).…”

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.

“…Also, improved interfacial adhesion between matrix, micro-fiber, and nanofillers may be ascribed to effective compatibilization by maleic anhydride grafted polypropylene (MA-g-PP) which resulted in hindrance of matrix-deformation at the elasticzone and subsequent modulus enhancement. Additionally, the arrangement of xGNP in the flow direction during extrusion and injection molding may have enhanced the drastic improvement in material flexural modulus [11,12]. However, treated kenaf flour-xGNP-RPP nanocomposites exhibited superior FM and FS values in comparison with the untreated materials, revealing that NaOH and C-TAB treatment of kenaf flour enhanced efficient transfer of stress from the polymer matrix to fiber.…”

Very recently emerging trends in polymer nanotechnology has revealed tremendous upsurge in application of graphene and derivatives in development of multifunctional nanocomposites. In present work, recycled polypropylene filled with increasing concentration of kenaf flour modified with sodium hydroxide/cetyl-trimethylammonium bromide (C-TAB) and filled with 3-phr graphene nanoplatelets (xGNP) hybrid nanocomposites were compatibilized using maleic anhydride grafted polypropylene and prepared via melt-intercalation using co-rotating twin-screw extruder subsequented by injection molding. The mechanical and morphological properties of NaOH-C-TAB modified materials (T-KRPPG) were studied and compared with untreated (U-KRPPG) samples. Transmission electron microscopy, field emission scanning electron microscope, Fourier transform infra-red spectroscopy (FTIR) and X-ray diffraction (XRD) analysis were applied in characterizing the microstructure and morphology of the materials. Mechanical tests revealed that tensile strength of T-KRPPG nanocomposites were superior in comparison with untreated (U-KRPPG) samples. In addition, the flexural strength, flexural modulus, and Young's modulus of C-TAB treated kenaf xGNP (T-KRPPG) nanocomposites were superior in comparison with the untreated (U-KRPPG) samples. The morphological images of the tensile fractured surface of modified T-KRPPG nanocomposites revealed reduction of microholes and fibres aggregation signifying enhanced xGNPfiber-matrix inter-facial adhesion due to kenaf flour modification with NaOH/C-TAB. XRD analysis revealed exfoliation and homogeneous separation of xGNP in matrix. FTIR analysis revealed no variations in peak positions of xGNP to suggest any significant chemical interactions between xGNP and other componenets.

“…This actually represented the highest tensile strength achievable from both alkali and combined alkali-bleach treatment. Hence, 2 wt.% NaOH treatments for 120 minutes, followed by bleaching at 2 wt.% NaClO 2 for 60 minutes, were considered as the optimum extraction parameters for screw-pine leaf which yielded the highest tensile strength of the treated cellulose fiber [22][23][24][25][26] . Cellulose fiber composite: Figure 7 shows comparison between the average tensile strength of the controlled sample, untreated and treated cellulose fiber composites.…”
