“…[8][9][10][11][12][13]. It is well known that the preference for green composites over neat polymers arises from their environmental sustainability, improved performance, cost-effectiveness, and potential for weight reduction [14][15][16][17][18]. Though, a great deal of technical challenges need to be solved, such as fiber-matrix adhesion, the raise of mechanical performance, poor flammability resistance, and moisture-uptake control [15][16][17][18].…”

Lignocellulosic-based polymer composites have gained significant interest due to their ‘’green’’ character as a response to environmental concerns. A diverse array of lignocellulosic fibers is utilized, depending on fiber dimensions, chemical composition, moisture content, and the fiber–matrix interface. The aim of this study is to establish an alternative standardized methodology, aimed at comparatively estimating the performance of polymer composites through the examination of individual plant fibers. The fibers studied are ramie, hemp, flax, and kenaf, and HDPE-based corresponding composites were analyzed for their performance across various fiber-content levels (10, 20, and 30 wt.%). It was found that kenaf showcases the largest average fiber diameter, succeeded by hemp, ramie, and flax. Additionally, ramie and kenaf exhibit elevated levels of crystallinity, suggesting increased cellulose content, with kenaf having the lowest crystallinity index among the fibers compared. Based on Thermogravimetric analysis, ramie displays the lowest moisture content among the examined fibers, followed by hemp, flax, and ultimately kenaf, which is recorded to have the highest moisture content, while, similarly, ramie exhibits the lowest mass loss at the processing temperature of the corresponding composites. Composites containing fibers with smaller diameters and higher crystallinity indexes and lower moisture absorptions, such as ramie and hemp, demonstrate superior thermal stability and exhibit increased Young’s modulus values in their respective composites. However, poor interfacial adhesion affects mechanical performance across all composites. Understanding fiber morphology, inner structure, and thermal stability is important for developing new composite materials and optimizing their selection for various applications.

The study aimed to investigate the flexural mechanical properties, thermal and morphological properties of polypropylene composites reinforced with cellulose and glass particles. Polypropylene lacks sufficient strength and stiffness for many applications. By reinforcing it with cellulose and glass particles, the study aims to enhance these mechanical properties, addressing the need for stronger and more durable materials. These composites are likely to find applications in the automotive industry where light weight, strong and heat resistant materials are needed for bumpers, dashboards, and interior trims. Additionally, these composites can be used for consumer goods where strong and lightweight materials are needed for various consumer products like furniture, sporting goods, and appliances. The use of the Finite Element Analysis to explore the properties of the cellulosic composites was done. Additionally, the experimental method was used to validate the results of FEA. The injection moulding process was used to fabricate the specimens for this study. The specimens were then characterized for their thermal behavior, morphology, and flexural properties. The thermal properties that were performed were the thermogravimetric analysis (TGA) and the differential scanning calorimetry (DSC). Moreover, the morphology of the fabricated samples was examined using the Scanning Electron Microscopy. The composites were fabricated at filler volume fractions ranging from 0% to 50%. The flexural strength of both the wood powder/ PP composites and the hybrid composites were found to be maximum for a filler volume fraction of 40% exhibiting 796.44 MPa and 1692.951 MPa, respectively. The research also noted from TGA that the melting temperature of all the fabricated samples were in the range of 150ºC to 160ºC. The glass transition temperature of neat polypropylene was around -20ºC.

Cattail (Typha), a wetland plant, is emerging as a sustainable materials resource. While most of the Typha species are proven to be a fiber‐yielding crop, Typha latifolia exhibits the broadest leaf size (5–30 mm), yields highest amount of fiber (≈190.9 g), and captures maximum CO2 (≈1270 g). Alkaline retting is the most efficient degumming process for cattail fibers to achieve maximum fiber yield (30%–46%). Cattail leaves exhibit a distinctive bionic structural model consisting of epidermis and leaf blade at macro level and non‐diaphragm aerenchyma, fiber cables, partitions, and diaphragms at micro level. Cattail fibers hold promise to be utilized as a high‐performance composite part and as efficient energy storage devices in clean energy vehicles. The former is attributed to their lower density (≈1.26–1.39 gm/cm3) and higher tensile modulus (≈66.1 GPa after treatment), while the latter is attributed to their porous structure and chemical stability. Therefore, integrating the knowledge of plant biology and materials chemistry is crucial for enhancing fiber characteristics and producing engineered bioproducts. The environmental benefits of cattails, degumming methods, leaf and fiber structures, their properties and applications is reviewed. Finally, it discussed future research directions aimed at developing bioengineered, biodegradable products from it with minimal environmental impact.
