“…Figure 6 showed that equal weight % share of PALF and sisal enhanced the overall mechanical attributes, e.g., ductile strength (207 MPa), bending strength (90.3 MPa), impact (29 J/m 2 ), and hardness (83.7). The mechanical test results revealed a regular trend of an increase in flexural, tensile, impact, and hardness with the addition of PALF fibers, and this was supported by various works [ 80 , 81 , 187 , 188 ]. Besides that, they concluded that this type of composite material could be valuable for multiple industries, including automotive and construction fields.…”

Increasing scientific interest has occurred concerning the utilization of natural fiber-enhanced hybrid composites that incorporate one or more types of natural enhancement. Annual natural fiber production is estimated to be 1,783,965 × 103 tons/year. Extensive studies have been conducted in the domains of natural/synthetic as well as natural/natural hybrid composites. As synthetic fibers have better rigidity and strength than natural fibers, natural/synthetic hybrid composites have superior qualities via hybridization compared to natural composites in fibers. In general, natural fiber compounds have lower characteristics, limiting the use of natural composites reinforced by fiber. Significant effort was spent in enhancing the mechanical characteristics of this group of materials to increase their strengths and applications, especially via the hybridization process, by manipulating the characteristics of fiber-reinforced composite materials. Current studies concentrate on enhancing the understanding of natural fiber-matrix adhesion, enhancing processing methods, and natural fiber compatibility. The optimal and resilient conceptions have also been addressed due to the inherently more significant variabilities. Moreover, much research has tackled natural fiber reinforced hybrid composite costs. In addition, this review article aims to offer a review of the variables that lead to the mechanical and structural failure of natural fiber reinforced polymer composites, as well as an overview of the details and costings of the composites.

“…The strength of hybrid fibers and the adhesion has improved the stress transfer and elastic deformation in epoxy-based composites [2]. Because of this, the BSPE composite has higher flexural strength and modulus than the other type of composites in this investiagtions and it was similar to [10][11][12][13][14]. The BPE, SPE, SBE, and BSPE composites can be a potential material to replace Acrylonitrile Butadiene Styrene (ABS) Plastic (figure 6(d)) presently being used in automobile interiors and it has a flexural strength in the range of 0.379-593MPa [29].…”

“…Alkalization cleans the outside of natural fibers of some undesirable substances. About developing the attachment among hydrophilic fibers and matrix, alkali treatment produces unpolluted and rough fiber surfaces with enlarged surface area, decreased fiber diameter, and increased aspect ratio [13,14] Banana based woven fabrics were chemically altered by Hetal Shah et al [10] by soaking in a NaOH concentration. And stated that the tensile-flexural characteristics of the chemically modified samples were higher than those of the untreated specimens.…”

To address the sustainable development goals, an attempt was made to investigate the alkaline treated and untreated Banana, Sisal, and Pineapple fiber epoxy hybrid composite for their mechanical and thermal properties. Tensile, Flexural, Impact, modulus, and Heat Deflection temperature (HDT) were evaluated and analyzed for low-load structural applications. The performance of Alkaline Treated Fiber composites was better than the untreated fiber composites. The treated Banana, Sisal, and Pineapple hybrid fiber epoxy composite has a high HDT value of about 78°C, a maximum tensile strength of 104 MPa, a tensile modulus of 25 MPa, a flexural strength of 78 MPa, a flexural modulus of 5286 MPa, and an impact strength of 286 J/m when compared to other composites. Interfacial failure analysis was also carried out with the help of a Scanning Electron Microscope (SEM) to study the microstructural behavior of the tested specimens. It was observed that the alkaline treatment increases fiber-matrix interaction.

“…Finally, the volume change that occurred in the densification process (∆V) was calculated to find the density of each biomass after being compressed. Type of RVE: By observing the internal organization of the materials that make up the sawdust and rice husk specimens, the RVE Chopped Fiber Composite was selected [31,32].…”

The development of this research work seeks to determine the mechanical behavior of the compacted mixture of pine sawdust and rice husk by varying the mass percentages of these biomasses obtained in briquettes, with the purpose of being marketed. The finite element software ANSYS is used to corroborate the results obtained for the samples named AIO, BIO and CIO with rice husk mass percentages of 25, 50 and 75, respectively. In the computational simulations, Young’s moduli of between 651 and 813 MPa and a Poisson’s ratio of 0.8 were found for all samples. In compression tests, Von Mises stresses of between 87 and 90 MPa and Von Mises strains between 0.09 and 0.12 m/m were found. Free-fall tests showed von Mises stresses below 4.24 MPa. It was determined that increasing the percentage of rice husk mass in the simulation models increased the value of Young’s modulus and compressive strength, this is a positive indication in relation to the strength of the formed briquettes, in case they are required to be transported for commercial purposes, however no defined stress and strain behavior was obtained for the impact tests, since the heights of 2 m and 5 m together with the masses established for the specimens do not cause high impact forces.
