“…Because the energy release is minimal, the fracture occurs early. [ 41 ] The addition of 5 wt% nanoclay to the polyester results in a 73.3% increase in storage modulus over the pristine polyester resin, which may be attributed to the improved dispersion of bentonite nanoclay in the polyester resin. As the temperature approaches the glass transition temperature ( T g ), the storage modulus of the composite falls, which is due to the composite's softness.…”

In this research, the effect of the addition of aluminosilicate (bentonite) nanoclay powder on the mechanical and dynamic mechanical behavior of polyester composites was investigated. Nanoclay laminates were fabricated in four different combinations, and the effect of nanofiller addition on the mechanical behaviors has been tested under ASTM Standards. The nanoclay and polyester resin were mixed using the ultrasonication process. Due to the enhanced interface between nanoclay and polyester, the flexural, tensile, and impact characteristics of laminates were boosted by clay addition. The loss modulus, storage modulus, and tan δ of the specimen were studied as a function of temperature and frequency of oscillation using a dynamic mechanical analyzer, and it was discovered that the addition of 5 wt% bentonite clay provided better strength and had the highest storage modulus than the other laminates. A morphology analysis was done on the fractured specimens through the scanning electron microscopy.

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.

“…The function of acrylonitrile-butadiene rubber (ABR) and nano-silica in epoxy composites with stitched E-glass fiber, with a novel approach of layering rubber sheet, resulted in improving the reinforcing effect in FRP and also confirmed that the accumulation of nano-silica enhanced the Mechanical properties of the composites. Rubber-based Epoxy composites with improved penetrations find major applications in automobile body panels, armor-based panels and also in domestic manufacturing applications [7,8]. An epoxy biocomposite was prepared using rice husk-derived ultrafine biosilica that possesses high-performance coating application in aircraft passenger air-duct application for heat reduction and to enhance the air's quality [9].…”

This study aims to reveal the consequence of thickness reinforcement on Fiber Laminates (Polyester Resin, Glass Fiber, Aluminum, and Bentonite) and to see if it can enhance the mechanical properties and resistance of laminates. Glass fiber reinforced polymer composites have recently been used in automotive, aerospace, and structural applications where they will be safe for the application s unique shape. Hand layup was used to fabricate three different combinations, including Aluminium /Glass fiber reinforced polyester composites (A/GFRP), Bentonite/Glass fiber reinforced polyester composites (B/GFRP), and Aluminium&Bentonie/Glass fiber reinforced polyester composites (AB/GFRP). Results revealed that AB/GFRP had better tensile strength, flexural strength, and hardness than GFRP and A/GFRP. Under normal atmospheric conditions and after exposure to boiling water, hybrid Aluminium&Bentonite and glass fiber-reinforced nanocomposites have improved mechanical properties than other hybrid composites. After exposure to temperature, the flexural strength, tensile strength and stiffness of AB/GFRP Composites are 40 % higher than A/GFRP and 17.44% higher than B/GFRP Composites.
