In this current study, high‐toughness epoxy bio‐composites were prepared and characterized for lightweight and low‐cost technological applications using novel palmyra sprout fiber (PSF) and red matta rice husk (RHA) biosilica. The principal aim of this research was to study how the alkali‐silane treatments on the fiber and particle influence the mechanical, wear, thermal and hydrophobic behavior of epoxy composites. The PSF was alkali‐silane treated whereas the biosilica was treated only with silane. The composites were prepared via a hand layup process and characterized. According to the results, the treated PSF with 3 vol.% RHA biosilica has the maximum tensile, impact, flexural strength, and hardness. The composite with the inclusion of 5 vol.% biosilica, and the palmyra sprout fiber has the lowest specific wear rate and COF of 0.007 mm3/Nm and 0.37. Moreover, these composites possess good thermal stability with the highest initial decomposition temperature of 342°C. Similarly, the composite designation ESP3 have the lowest contact angle of 75.7°, which is within the hydrophobic limit. These composites with improved mechanical, thermal and wear properties may be useful in a variety of engineering applications that can be used for high load‐bearing capacity and biodegradability, such as sporting goods, automobiles, home furniture, food packaging, transport, and aircrafts.

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.

“…Silica nanoparticles have been explored to enhance the mechanical and physical properties of composites. Nevertheless, their specific influence on jute fiber-reinforced composites with epoxy matrices remains relatively unexplored [4]. Recent years have seen the application of machine learning, particularly artificial neural networks (ANNs), to predict material characteristics accurately, thus reducing the need for extensive experimental testing.…”
