“…The density and volume fraction of voids have an impact on the mechanical properties of the composites, and this has been ascertained from the studies of Mehdikhani et al, who have reviewed the formation of voids and their effect on the characteristics of the composites. The increase in the volume fraction of the voids has a detrimental effect on the properties of the composites [65,71,72].…”

Natural fiber-reinforced polymer composite is a rapidly growing topic of research due to the simplicity of obtaining composites that is biodegradable and environmentally friendly. The resulting composites have mechanical properties comparable to synthetic fiber-reinforced composites. In this regard, the present work is formulated with the objectives related to the development, characterization, and optimization of the wt% of reinforcements and the process parameters. The novelty of this work is related to the identification and standardization of the appropriate wt% of reinforcements and parameters for the processing of the areca nut leaf sheath fiber-based polymer composites for enhanced performance attributes. With this basic purview and scope, the composites are synthesized using the hand layup process, and the composite samples of various fiber compositions (20%, 30%, 40%, and 50%) are fabricated. The mechanical characteristics of biodegradable polymer composites reinforced with areca nut leaf sheath fibers are investigated in the present work, with a focus on the effect of fiber composition (tensile properties, flexural strength, and impact strength). The properties of composites are enhanced by combining the areca nut leaf sheath fiber and epoxy resin, with a fiber content of 50% being the optimal wt%. The Scanning electron microscopy (SEM) investigations also ascertain this by depicting the good interfacial adhesion between the areca nut leaf sheath fiber and the epoxy resin. The tensile strength of the composite specimen reinforced with 50% areca nut fiber increases to 44.6 MPa, while the young’s modulus increases to 1900 MPa, flexural strength increases to 64.8 MPa, the flexural modulus increases to 37.9 GPa, and impact strength increases to 34.1 k J/m2. As a result, the combination of areca nut leaf sheath fiber reinforced epoxy resin shows considerable potential as a renewable and biodegradable polymer composite. Furthermore, areca nut leaf sheath fiber-reinforced epoxy resin composites are likely to replace petroleum-based polymers in the future. The ecosustainability and biodegradability of the composite specimen alongside the improved mechanical characteristics serve as the major highlight of the present work, and can help the polymer composite industry to further augment the synthetic matrix and fiber-based composites with the natural fiber-reinforced composites.

[55,58] 3.9 | Flexural properties of raw and optimally alkalized ZN fiber-based polymer composites Flexural strength is the ability of a material to resist bending forces applied perpendicular to its longitudinal axis. Since the application of load is done perpendicular to the horizontal axis of samples the interlaminar forces regulate the composite's flexural behavior.…”

The global trend of environmental protection has led to replacing synthetic fibers in every feasible application with natural fibers. An alteration of the fiber's surface is essential for the natural fiber to be more suitable for use. In this study, the mercerization processes including 5% (wt/vol) sodium hydroxide solution at five different soaking times (15, 30, 45, 60, and 75 min), were used in this study to enhance various features of Ziziphus nummularia fibers isolated from Ziziphus nummularia plant stems. Results showed that 60 min alkalized Ziziphus nummularia fibers had cellulose content of 65.72%, which seems to be higher, and it was termed as optimally alkalized Ziziphus nummularia fibers. The thermal studies showed that optimally alkalized Ziziphus nummularia fibers had a degradation temperature of 360 C. The optimally alkalized Ziziphus nummularia fibers showed a crystalline index of 50.6% and crystal size of 3.52 nm. Epoxy composites were manufactured with various loading percentages of optimally alkalized and raw Ziziphus nummularia fibers to prove the application suitability. It was shown that 20 wt% of optimally alkalized Ziziphus nummularia fibers-based epoxy composites showed a higher ultimate tensile strength of 40.31 MPa than all other composites. Scanning Electron microscope studies elucidated the fiber's surface behavior and other characteristics of fibers and tested epoxy composites.

“…Major importance is given to these composites over synthetic fiber composites for its numerous advantages which include low impact environment, low cost, light weight, biodegradable, non-toxic, non-combustible, easy availability, low density, and recyclability. [1][2][3] However some of its limitations are poor dimensional stability, incompatibility of fibers with some polymeric materials and high moisture incorporation of fibers, which demolish them for certain applications. [4] Much effort is given in improving the mechanical performance of this group of materials to expand the capabilities and applications.…”

“…Torres et al [9] discovered that 3% stearic acid concentration caused the fiber's surface to be modified to the point where the attributes stated were optimal. Most of the study have been done on various natural fiber-based composites and their surface treatment such as Bagasse, [10] jute, [11] hemp, [12,13] luffa, [14] banana, [15] date palm, [3] and coir [16] as reinforcing materials in polymeric matrices composites fabricated from chemically treated fiber shows superior mechanical properties than the raw one. [17] Sahoo et al [18] observed that impact strength increases with fiber loading.…”

In this research, a newly explored natural fiber named sea purslane fiber (SP) was applied as a reinforcing material with widely used thermosetting polymer epoxy polymer. Chemical treatments on the fibers were done with NaOH followed by acrylic acid treatment. Reinforcing acrylic acid treated and untreated SP fibers at variable weight percentages of fiber loading, variety of composite samples (0, 5, 10, 15, 20, and 25 wt%) were developed. The mechanical characteristics of the composites were found to improve initially with increasing filler content until reaching the optimum (20 wt%) fiber loading, after which they began to fall. At 20 wt% filler loading various properties like physical & chemical (density, water absorption, X-ray diffraction), mechanical (tensile, flexural, impact, micro-hardness) and thermal (thermogravimetric analysis) properties were examined and compared with untreated fiber reinforced composites. It was noticed that the treated fiber composites reveal better result as compared with untreated fibers composites. The findings provide manufacturers and engineers with a broad concept of how to use this composite to reduce weight, particularly in automotive applications.
