Summary: This research investigates the physical and mechanical properties of hybrid composites made of epoxy reinforced by kenaf and flax natural fibers. The results showed that the density of the hybrid composites remained unchanged, and increasing the kenaf fiber volume fraction improved the tensile, flexural, and interlaminar shear performance. The stacking sequence significantly affected the mechanical properties of the hybrid composites.

Summary: The environmental benefits, renewability, and low cost of natural fiber-based hybrid composites have attracted significant interest. However, the hydrophilic behavior and high moisture absorption of natural fibers lead to poor bonding and reduced performance of the composites. This can be addressed by hybridizing natural fibers with inorganic fillers, such as nanoclay. Nanoclay improves the mechanical and thermal properties of the composites and reduces the impact of moisture. This review focuses on the use of kenaf and bamboo fibers, as well as the effect of different nanoclay on the properties of natural fiber-based hybrid composites.

Summary: This investigation explored the dynamic mechanical properties of Indian almond - Kenaf fiber composite and analyzed the effect of stacking sequence. The experimental results showed that the kenaf fiber composite exhibited superior storage modulus and loss modulus values compared to other composites due to the high stiffness of kenaf fiber and better bonding between the matrix and fiber. Among the hybrid composites, the Kenaf/Indian almond/Kenaf composite displayed higher moduli due to the presence of two layers of high stiffness kenaf fiber. The thermal stability of the composites followed the order of Kenaf > Kenaf/Indian almond/Kenaf > Indian almond/Kenaf/Indian almond > Indian almond. The Indian almond fiber composite and Indian almond/Kenaf/Indian almond composite showed good damping properties due to the higher mobility of polymer chain. The cole-cole plot indicated that all the fabricated composites had heterogeneous structures, with the kenaf fiber composite displaying the highest heterogeneity among all materials. The modeling of storage modulus and damping factor showed good agreement with the experimental results.

Summary: With the aim of developing light-weight materials for automotive and aerospace applications, aluminum-based hybrid nano-composites (AHNCs) were manufactured using the compocasting approach in this study. Chopped carbon fibers (CFs) and different weight fractions of nanoclay (1-5%) were reinforced in the matrix of AA6026 to form AHNCs. The AHNCs specimens underwent microstructural analysis, mechanical characterization, fatigue, and corrosion strength tests according to ASTM guidelines. Electroless plating method was used to coat CFs with copper for improved wettability with the matrix. SEM images of the manufactured composites showed thin inter-dendritic aluminum grains with eutectic precipitate particles at intergranular junctions, as well as nanoclay particles precipitated in the matrix. Tensile strength (TS) increased with the inclusion of nanoclay up to a maximum of 212.46 MPa for 3% nanoclay reinforcement, beyond which it decreased due to non-homogeneous distribution, agglomeration, and debonding of nanoparticles. Similarly, micro-hardness increased with the addition of 3% nanoclay, after which it decreased. Higher energy absorption and significant improvement in flexural strength were achieved with 3% nanoclay reinforcement. The fatigue strength of the hybrid composite tended to increase with the addition of both CFs and nanoclay until 3% addition, as the flexible CFs and high surface area nanoclays strengthened the grain boundaries. Furthermore, the addition of nanoclay reduced the corrosion rate by filling the crevices and voids in the matrix.

Summary: The use of kenaf fibers as a natural reinforcement in polymer composites has gained significant attention in recent years due to their good mechanical properties, eco-friendly and biodegradable characteristics. By reinforcing unsaturated polyester (UPE) with kenaf fibers, the properties of the polyester resin can be improved, primarily through enhancing the interfacial adhesion between the fibers and the resin. Chemical modifications are commonly employed to further enhance this interfacial bonding, leading to improved mechanical properties of the composites. This paper explores previous studies on kenaf fiber reinforced UPE composites, focusing on processing methods, mechanical properties, water absorption, and morphology, serving as a valuable resource for future research in this area.

Summary: This research investigates the effects of incorporating microcrystalline cellulose (MCC) into beaten oil palm empty fruit bunch (EFB) fibers for papermaking. The addition of MCC decreases the porosity and increases the opacity of the paper. The paper with 6% MCC addition shows the highest mechanical properties, especially in terms of tensile strength. Beating revolution also plays a significant role in influencing the strength of the papers made from EFB fibers with MCC. The produced paper has potential in the manufacturing of writing or high-quality printing grade paper.

Summary: This study explores the use of response surface methodology (RSM) to predict the compressive strength of bio-mortars and determine the optimal values for each parameter. Experimental and statistical analyses show that partially replacing cement with biochar produced from Washingtonia filifera waste pyrolysis improves the compressive strength and thermal conductivity of the bio-mortars. The findings demonstrate the feasibility of producing bio-mortars with a compressive strength of 63.81 MPa, a 1% replacement rate of biochar, and a coefficient of thermal conductivity of 0.52 W/m.K.

Summary: This study investigates the shape memory properties of a shape memory epoxy polymer (SMEP) nanocomposite incorporated with a hybrid of multi-walled carbon nanotube (MWCNT) and montmorillonite nanoclay (MMT). The nanocomposites were characterized through cyclic thermomechanical tests and fold-deploy tests. The inclusion of the hybrid nanofiller resulted in a decrease in shape recovery, except for the SMEP nanocomposite. The recovery through thermal and electrically activated methods showed similar profiles, with electrically activated recovery reacting faster. The effect of nanofiller inclusion was more prominent in the thermal activation method. The hybrid filler SMEP nanocomposite with 3 wt.% MMT and 1.0 wt.% MWCNT exhibited better shape memory properties. These findings provide guidance for selecting nanofiller loadings based on performance for specific applications in industries such as aerospace, medical, and automotive.

Summary: In this study, PLA/NF biocomposites were prepared by melt extrusion method using locally grown natural fibers as fillers. PEG was added as a plasticizer to improve the processability of the PLA. Mechanical and thermal characterization were conducted to assess the processing effects of PLA/NF biocomposites. The results showed that the mechanical properties of PLA/NF biocomposites were improved compared to PLA. The DMA and TMA analysis revealed slight reduction in storage modulus and loss modulus, while the T-g values from DSC analysis remained unchanged. TMA analysis also showed a significant decrease in coefficient of thermal expansion values for PLA/NF biocomposites. Overall, PLA/NF biocomposites have the potential for novel biocomposite applications, especially in biomedical field, due to their good stiffness, tensile strength, and dimensional stability.

The accumulation of plastic waste materials poses a severe burden on the environment due to the increasing demand for plastics. Thermo-catalytic conversion of plastic waste materials to hydrogen and other fuels is a promising long-term solution to this environmental challenge, but the development of durable and high-efficiency catalysts is a potential challenge for researchers.
