“…The presence of sisal fibers and fly ash nano-fillers increased the tensile strength and modulus of the pure bio-epoxy resin as also reported by Pappu et al 21 It was also evident that the addition of fly ash nano-fillers improved the tensile properties of the hybrid composite up to 10% fly ash weight fraction, but beyond that, the properties decreased. Tensile testing revealed that the addition of sisal fibers and fly ash nano-filler increased the overall tensile strength of the composite by 130% while the tensile modulus increased by 183% as also observed by Kamaraj et al 22 This result is due to the reinforcement provided by the sisal fibers and the improvement in the mechanical properties brought by the fly ash nano-filler. The combination of sisal fibers and fly ash nano-filler in the composite also resulted in increased resistance to cracking and improved toughness compared to traditional epoxy composites without these reinforcements.…”

This research investigates the mechanical characteristics of a novel hybrid composite material, which combines bio-epoxy reinforced with sisal fiber and integrated with fly ash nano-fillers. The study focuses on exploiting the environmentally friendly attributes of natural fiber composites and reducing reliance on synthetic materials. In this study, sisal fiber serves as the reinforcement, and a bio-epoxy matrix is utilized to create the composite. To further enhance its properties, fly ash, a byproduct of coal-fired power plants, is incorporated as a nano-filler. The experimental findings reveal significant improvements in the mechanical properties of the composite due to the inclusion of fly ash nano-fillers. The tensile strength shows a notable enhancement of up to 6.3%, flexural strength experiences an impressive increase of 68%, impact strength demonstrates a remarkable boost of 28%, and scratch hardness elevates by 17% which were all achieved at 20% fiber weight fraction and 5% fly ash weight fraction. The considerable potential of this hybrid sisal fiber reinforced bio-epoxy composite, integrated with fly ash nano-fillers, as an eco-friendly alternative to traditional synthetic composites is evident from these results. Such enhancements make the composite suitable for a wide range of engineering applications, including the manufacturing of automotive components, construction materials, and consumer goods. By adopting this bio-composite, industries can actively contribute to sustainable practices while maintaining optimal performance in their products. This research offers valuable insights into a promising solution for eco-conscious engineering applications, with both quantitative and qualitative evidence demonstrating the achievement of superior mechanical properties in this innovative hybrid material.

“…Reports shows that sisal fibre consists of 43%-56% cellulose, 21%-24% hemicellulose, 7%-9% lignin and 0.6%-1.1% ash . Its high cellulose content makes it to be hydrophilic in nature and hence, difficult compatibilty with hydrophobic polymer matrix usually ensue (Kamaraj et al 2018). Thus, chemical treatments are carried out to improve compatibility between the fibre and the polymer matrix (Manoj Kumar et al 2019).…”

This study investigates the effects of calcined and uncalcined eggshell particles (ESP) and sisal fiber (SF) on the mechanical and wear properties of eggshell particles/sisal fiber reinforced epoxy composites. Egg shell was processed to obtain calcined and uncalcined egg shell particulate of −43 μm and sisal fibers was extracted by soil retting and treated with NaOH. The composite was developed using the hand lay-up method by blending the selected materials in predetermined proportions. SEM/EDS and XRD of the egg shell particles were carried out while mechanical and wear properties of the developed composites were evaluated. SEM images of the fracture surfaces were also examined. The results showed that eggshell particles contain CaCO 3 and the uncalcined ESP/SF reinforced epoxy composite showed improved properties than the calcined ESP/SF composites in most of the tests performed. Also, it was observed that most of the tests gave the best results at different weight fractions. However, 3 wt. % emerged as the weight fraction with optimum values.

“…In such cases, the nodes on the intersection of ribbons shall collect more particles than straight ribbons. This property can improve and reinforce the fibrous structure of cupric oxide matrix composite having different mechanical properties [42, 43]. The explicit phenomenon of non‐random of ribbons‐particles mixing is that the attachment occurs precisely at the nodes of contact of fibers more than other locations of the material as shown by the arrows, Figure 6b–c.…”

In the present work, we investigate the surface, and bulk structural properties of composite cupric oxide ribbons, and zinc oxide particles. The composites are synthesized using the technique of solution combustion. Crystallographic phases are confirmed using the x‐ray diffraction technique and proved the formation of monoclinic cupric oxide and hexagonal zinc oxide crystallites. Scanning electron microscope and high‐resolution transmission electron microscope are used to examine the morphology of the prepared materials. Composite mixtures of raw particles cupric oxide and zinc oxide are used as benchmark morphologically‐alike composite materials. The specific surface area values of the studied materials are investigated using nitrogen gas adsorption at 77 K while the spectroscopic gamma ray attenuation is used to determine the effective density of the different samples. Zinc oxide particles are dispersed on cupric oxide ribbons and cause nonlinear dependence of the specific surface area and density on the composition ratio due to the physical contact between particles, especially at the voids and the nodes of the fibrous ribbons network.
