“…[469][470][471][472][473][474][475][476][477][478] One of the most important challenges facing researchers today is to achieve satisfactory interfacial bonding between natural fibers and polymers. [478,[480][481][482][483] This is quite difficult to achieve because of the hydrophilicity of fibers and the hydrophobicity of polymers. [484][485][486] However, chemical and surface treatments are a good solution to overcome this problem.…”

Environmental awareness across the world has motivated researchers to focus their attention on the use of cellulosic fiber as reinforcement in polymer matrices.Lignocellulosic fibers are an abundantly available resource in all countries, which is cheap and easily renewable. Also, due to their properties, cellulosic plant fibers exhibit a great potential for use in polymer reinforcement. As a result, considerable research and development efforts have been directed towards the use of cellulosic fibers as a reinforcing material in composites. The use of cellulosic fiber reinforced composites has continuously increased during recent years, which benefits the cultivation of fiber plants and the economy of the country. This research area continues to be of interest to both industry and academia, the use of cellulosic fibers in composite applications being investigated throughout the world. Cellulosic fiber reinforced composites are reasonably strong, lightweight, harmless to human health and the environment, and biodegradable, hence they have the potential to be used in various applications. Recent progress in cellulosic fiber composites research has illustrated their great potential as structural components in automobiles, aerospace structures, construction, and building, and so forth. This study is an effort to create awareness about the research works that have been published in the field of natural fiber composites. This review briefly illustrates the main paths and results of major research published in the field of natural fiber reinforced polymer composites. The topics covered include the aspects of fiber treatment to improve the mechanical properties of the composites, manufacturing methods, performance of hybrid composites, effect of laminate configuration, and many different applications of natural fiber composites.By presenting a systematic view of the work performed in this area so far, this review will hopefully serve as a starting point for the development of new ideas in the research on natural fiber polymer composites.

Researchers are continuously working to improve the mechanical characteristics of polymer composites by various approaches such as fiber treatment, filler addition, and others. In this study, mechanical, thermal, and morphological characteristics of composites produced from corn husk waste fibers treated with pumice powder were examined. Corn husk (CHF) and pumice powder (SBA) were mixed in polyester matrix at varied volume fractions of 5: 30, 10:25, 15:20, 20:15, 25:10, and 30:5. The results demonstrate that infusing SBA into the CHF composite enhanced the interfacial adhesion between the CHF and the polyester matrix. As a result, the mechanical and thermal characteristics of the SBA/CHF composites were significantly improved. The composite with 5:30 volume fraction (JPA) exhibited the highest values of tensile strength (18.61 MPa), tensile modulus (3.23 GPa), flexural strength (36.12 MPa), and flexural modulus (3.39 GPa) among all the composites and the polymer matrix which was attributed to the strong SBA/CHF interface bonds in the composites. While the lowest values recorded for the composite specimens were due to a large number of CHF pullouts. Similarly, JPA composites outperformed the other composites in terms of thermal stability. The morphological study indicated that CHF pullout increased with an increased quantity of CHF and dropped as the amount of SBA increased and was distributed equally in the composite. According to the findings, the CHF/SBA composites had better mechanical characteristics than the fiber-glass composites.

“…Therefore, the development of polymer materials is to replace nondegradable petroleum-based plastics with degradable. [6][7][8] Biodegradable polymer materials mainly include polylactic acid (PLA), polybutylene adipate-co-terephthalate (PBAT), polybutylene succinate (PBS), and polyhydroxyalkanoate (PHA). Among them, PLA has excellent comprehensive properties and good degradability.…”

Polylactic acid has good biodegradability and it is dosage is increasing. Therefore, the degradation of PLA has become a new problem that needs serious management. In this study, the spores of Aspergillus niger were inoculated onto wheat straw/PLA composites containing different contents of sodium alginate, and the mass loss and characterization (microstructure, fourier transform infrared spectroscopy, thermal properties, and X‐ray diffraction) of the composites were detected. The objective was to explore the possibility of degradation of PLA composites by A. niger and the effect of sodium alginate on the degradability of PLA composites. The results showed that when the amount of sodium alginate was 3% and 6%, the mass loss rate of the composites only increased at the initial stage of degradation. However, when the amount of sodium alginate was 9%, the mass loss rate of the composites was significantly increased. It was found that A. niger could colonize the surface of the composites and cause cracks and depressions on the surface by morphological observation. The infrared spectral curve showed that the number of hydroxyl and carbonyl groups in the composites increased after degradation. According to the thermogravimetric curve of the composites, the pyrolysis temperature of the composites with sodium alginate content of 9% increased and the residual mass decreased after degradation. When the amount of sodium alginate was 9%, the crystallinity of the composites was greatly reduced, and it is crystallization zone was easier to degrade compared with other treatments. The results would provide a theoretical support for the rapid degradation of PLA composites.
