Natural fiber such as bamboo fiber, oil palm empty fruit bunch (OPEFB) fiber, kenaf fiber, and sugar palm fiber-reinforced polymer composites are being increasingly developed for lightweight structures with high specific strength in the automotive, marine, aerospace, and construction industries with significant economic benefits, sustainability, and environmental benefits. The plant-based natural fibers are hydrophilic, which is incompatible with hydrophobic polymer matrices. This leads to a reduction of their interfacial bonding and to the poor thermal stability performance of the resulting fiber-reinforced polymer composite. Based on the literature, the effect of chemical treatment of natural fiber-reinforced polymer composites had significantly influenced the thermogravimetric analysis (TGA) together with the thermal stability performance of the composite structure. In this review, the effect of chemical treatments used on cellulose natural fiber-reinforced thermoplastic and thermosetting polymer composites has been reviewed. From the present review, the TGA data are useful as guidance in determining the purity and composition of the composites’ structures, drying, and the ignition temperatures of materials. Knowing the stability temperatures of compounds based on their weight, changes in the temperature dependence is another factor to consider regarding the effectiveness of chemical treatments for the purpose of synergizing the chemical bonding between the natural fiber with polymer matrix or with the synthetic fibers.

Wood fiber reinforced thermoplastic composites are regarded as a kind of environmentally friendly material obtained by combining recycled thermoplastic and wood fibers together. However, they are difficult to be decorated for using due to their non‐polar, dense, and smooth surface characteristics. In this study, methods for improving the bonding strength between wood veneer and wood fiber/high‐density polyethylene (WF/HDPE) board were explored. A macromolecular coupling agent, allyl polyoxyethylene polyoxypropylene epoxy‐terminated polyether (AEPH) grafted γ‐aminopropyl triethoxysilane (KH‐550) was synthesized to treat wood veneer prior to lamination with WF/HDPE board. For further improving the bonding strength between wood veneer and WF/HDPE board, a low‐density polyethylene (LLDPE) film was inserted between as adhesive. As control, KH‐550, a commonly used coupling agent and water were also used to treat the veneer. Infrared spectroscopy measurement showed that the LLDPE film combines well with both the veneer and WF/HDPE composite board. Surface bonding strength test proved that all treated veneers significantly improved the combination with WF/HDPE substrated and the LLDPE intermediate film played a key role in it. The veneering endowed the WF/HDPE composite board much better flexural properties, up to 77.39 MPa, which is 50% higher than that of WF/HDPE substrate. The AEPH‐KH‐550‐treated veneer presented the highest bonding strength and best water resistant for glue line.

Synthetic plastics have several concerns for the environment, such as their impact on climate change, their long degradation time, or their degradation to microplastics that threaten animal life in the sea. The application of natural fibers as reinforcement in synthetic polymeric matrixes has several advantages in properties such as low density, lower cost of production, biodegradability, and a reduction of the environmental impact in the polymer industry. In this study, the Ecuadorian Guadua Angustifolia Kunth fiber was extracted and treated physically and chemically for its use as reinforcement in composite preparation. Maleic anhydride was used as a coupling agent to improve the interaction between the natural fiber and the low-density polyethylene (LDPE) polymeric matrix. The composite production was done using different bamboo particle loading (1-5% w/w) at a constant particle size (150 µm). Chemical, physical, and mechanical properties were evaluated to characterize the fiber and biocomposites. The chemical treatment of the fiber with 2% of NaOH showed a reduction of the lignin content confirmed by Fourier-Transform infrared spectroscopy. A total of ~39% mass loss related to the lignin, waxes, and other organic content was reached. In addition, a reduction in the density from approximately 0.87 to 0.66 was shown when increasing the content of bamboo in the composite. In the same way, the crystallinity was reduced by 3%. The composite with 1% bamboo presents a tensile strength of 10,66 MPa. The use of bamboo fiber in the biocomposites reduces the global warming potential concerning the increasing amount of fiber.
