In this present study, a natural fiber-based fiber metal laminate (FML) was fabricated for various engineering applications. The primary aim of this present investigation was to study the effect of adding natural fiber along with metal and the effect of the surface-treatment process on the reinforcements on load-bearing and thermo-mechanical properties. Okra fiber woven mat, aluminum 2024-T3 foil and rice husk-derived biosilica were used as reinforcements.For surface treatment, the metal foil was sandblasted whereas the okra fiber and biosilica were silane-treated. The FML was fabricated using the vacuum bag method utilizing as-received and silane-treated reinforcements as two separate models. According to the results, the addition of Al foil and okra fiber improved the storage modulus and loss factor of about 4.2 GPa and 0.39 for surface-treated reinforcements. Similarly, maximum fracture toughness and energy release of 39.42 MPa √m and 0.76 MJ/m 2 for surface-treated EOA2 composite designation. Moreover, the addition of okra fiber and Al foil increased the fatigue life counts up to 54,266, 48,116, and 26,263 for surfacetreated EOA2 composite at 30%, 60%, and 90% of ultimate tensile stress (UTS).Such thermo-mechanical and load-bearing properties improved FMLs could be used in automotive, aircraft, drone and other industrial applications requiring high structural rigidity and load absorbing capability.

“…This also occurred if alkaline-silane (PStd) and alkaline fibers (PSt) were compared (both treatments led to similar results). Although some authors confirm that the silane molecule can degrade the most amorphous compounds [52][53][54], there are others who agree that the silane molecule only covers the fiber [55] to subsequently act as a bonding bridge between reinforcement and matrix.…”

During the control campaigns of Pennisetum setaceum (invasive species widespread worldwide), the generated waste has accumulated in landfills. This study investigates its use to obtain P. setaceum fibers for their application as reinforcement of polymeric materials for injection molding, thus facilitating and promoting alternatives for the long-term sustainable management of P. setaceum. The extracted fibers were treated with alkaline, silane, acetic acid, and combined alkaline and silane treatments. Different composites with 20 and 40 wt% of fiber were extruded, and test samples were obtained by injection molding using recycled polyethylene as matrix. The composition of the fibers was determined by gravimetric methods, and contrasted with the analysis of the functional chemical groups using Fourier Transform Infrared Spectroscopy. Increases of up to 47% in the cellulose content of the treated fiber were observed. The thermal degradation was also evaluated using thermogravimetric analysis, which determined an increase in the degradation temperature, from 194 to 230 °C, after the combined alkaline–silane treatment. In order to analyze the differences in the composites, tensile, flexural, and impact properties were evaluated; in addition, differential scanning calorimetry was performed. Regarding the flexural behavior, it was possible to improve the flexural modulus up to 276% compared with that of the unreinforced polymer.

“…Biosilica, biochar, cellulose, and chitosan are some examples of bio particles that are now commonly used in composites. [ 10 ] Biocompatibility, high thermal stability, high tensile strength, and high modulus are few of the desirable features of cellulose that make it a versatile and necessary material for manufacturing biocomposite. Liu et al [ 11 ] researched on characterization of silane treated and untreated natural cellulosic fiber from corn stalk waste as potential reinforcement in polymer composites.…”

This investigation aimed to determine the effect of adding Vitis vinifera stalk cellulose (VSC) to epoxy resin composites reinforced with Bambusa vulgaris fiber (BVF). This study also focused on the mechanical, dynamic mechanical analysis, and fatigue properties of epoxy composites fabricated using VSC and BVF. The composite laminates were prepared using a hand layup method and were evaluated with respect to the corresponding ASTM standards. The mechanical properties illustrate that the increment in values for tensile strength and modulus, flexural strength and modulus, Izod impact as well as hardness maximum up to 162 MPa, 6.21 GPa, 182 MPa, 6.48 GPa, 5.72 J, and 90 shore‐D, respectively for 5.0 vol% of BVF and 40 vol% of bamboo fiber composite designation EBG3 (Epoxy + Bamboo + Grape cellulose). Similarly, the addition of BVF by 40 vol% improved the storage modulus, loss factor, and fatigue life count of composite “EB” (Epoxy + Bamboo) by about 2.91 GPa, 0.55 and 19,227, respectively. The highest observed storage modulus and minimum loss factor were about 4.14 GPa and 0.36 for the composite designation “EBG3” as well as the maximum observed fatigue life counts were about 34,227 for the same. These composites with mechanically strong properties with improved thermo‐mechanical properties and fatigue life could be applicable in automotive side door beadings, ballistic resistance defense equipments, sports goods, and also in some of the household gadgets making purposes.
