“…Hung et al reported the improved storage modulus and T g for dispersed GO‐CF composite and electrophoretic deposited GO on CF fabric composite 16 . Similarly, many researchers have used GO to improve the dynamic mechanical properties of epoxy resin composite properties 56–61 . All previously reported studies either used a complicated method to modify GO or an excess nanofiller amount.…”

Curved geometry in unidirectional CFRP (UD‐CFRP) demands ideal shape optimization to attain superior performance while maintaining the desired high strength to weight ratio. Herein, the effect of graphene oxide (GO) as the potential filler to improve the mechanical and thermal properties of flat and curved specimens of UD‐CFRP was investigated. The GO was synthesized using Hummer's method and introduced in the epoxy resin by wet transfer technique. Three‐point and four‐point bending analysis of UD‐CFRP showed maximum flexural strength and modulus at 0.3 wt% GO addition in UD‐CFRP. The improved interfacial adhesion of 0.3 wt% GO incorporated UD‐CFRP was realized by calculating storage modulus, reinforcement efficiency factor (r), C‐factor, adhesion factor, cross‐linking density, and glass transition temperature (Tg) from dynamic mechanical analyzer. Fracture analysis by scanning electron microscope showed the superior interlocking in carbon fiber, and epoxy polymer at 0.3 wt% GO addition.

“…The explanation for the enhancement is the stronger interface connection formed between the matrix and the fiber. In cellulosic fiber composites, Thangaraj et al [24] and Singh et al [25] addressed the use of nanoscale silicon fillers. The modulus of elasticity, elastic strength, and toughness were all increased by 14.40%, 7.50%, and 6.10%, respectively.…”

“…Nanosilicon offers a strong mix of qualities, like nontoxic, better interface with matrices, rust, and stability, among numerous second-stage reinforcements employed. SiO 2 is a naturally present silicon oxide that has attracted considerable attention due to its unique architectural, physiological, electrical, photonic, enzymatic, electrical, and anticorrosive properties [24,25]. Chemicals' insolubility, cheap price, excellent adhesion with other substances, and a strong index of refraction all attract interest.…”

Natural fiber composites are now more costly than traditional building materials. Currently, industries are moving from traditional materials to natural fiber composites, and the price of natural fiber should be reduced through greater utilization of industrial production. This work aims to determine how matrix alteration affects the interlaminar characteristics of a hemp fiber-reinforced epoxy composite containing nano silicon oxide particles. Interlaminar modulus of rupture in Types I and II is assessed using dual cantilevered beams and end-notched deformation testing samples. Mechanical mixing and sonication are used to blend nanoscale SiO2 (30 nm) into the resin at concentrations of 0, 0.2, 0.4, and 0.6 wt%. The composites were made using the compression molding method. The composites were tested according to the American Society for Testing and Materials standards after manufacturing. The findings show that adding nanoparticles enhances interlaminar toughness values. Interlaminar fracture toughness improved by 20.25% and 30.35% for 0.4 wt% SiO2, respectively. The fiber matrix interaction and failure causes are examined using scanning electron microscope images.

“…Nanomaterials have substantially bigger exchanging surfaces than microscopic sizes for a particular load. On the other hand, these composites will get a superior load transfer inside a framework [17]. The inclusion of microfilmers increases the matrix's mechanical qualities, although at the expense of other features.…”

In current centuries, emphasis has moved from previous resources and compounds to lightweight substances to generate softer, most effective components for particular needs. Using organic kenaf fibers with nanoreinforced epoxy polymers in a blended microbially nanocomposite can improve properties and be environmentally friendly. Adding graphene powder to the epoxy resin increases barrier and mechanical properties while maintaining rigidity without compromising toughness. To explore the impression of such parameters on the materials’ properties of the construction, a mechanical test on nanocomposite features, such as size, filler content, and treatment effect, may be utilized. The elastic behavior, tension characteristics, and stress at vintage for three types of nanobased materials were calculated using the test results: graphite raw kenaf, nanosheets and sun-bleached kenaf fibers, salinized graphene oxide, and epoxy reinforced with salinized kenaf fibers. The impact of nanocomposite magnitude, filler concentration, and filler processing on mechanical properties is carefully investigated. According to the findings, the three-weight proportion of 75 nm-sized particles with salinized filler and kenaf fiber produces the maximum mechanical performance. Compared to other combinations, these combinations increase tensile strength by 16%. However, it appears to be beneficial when it comes to strength properties and deflection. Because of flaws and cavities at the micrometer level, the framework was less robust and distorted quickly after including a nanoparticle filler.
