“…It was attributed that agglomeration of HNT hindered stress transfer among matrix and reinforcing material according to compression test results. [ 54 ] However, the compression strength of the nanocomposite with high‐level content of HNT had more superior value than one of neat PLA as shown in Table Table 5 and Figure 9. PLA‐(%1HNT‐MET) with loading MET had a negligible effect on compression strength and elongation according to PLA‐%1HNT.…”

In this study, multifunctional polymer nanocomposite scaffolds were fabricated by the fused deposition method (FDM) for biomedical applications. First, halloysite nanotube reinforced (1–5 wt%) polylactic acid filaments were prepared by melt mixing process. For the selected compositions, HNT was loaded with metformin (MET) by electrostatic interactions. The characterization of the scaffolds was observed by Fourier transform infrared spectroscopy, X‐ray photoelectron spectroscopy, differential scanning calorimetry, and thermogravimetric analysis. The morphology of the nanocomposite scaffolds was investigated by scanning electron microscope. Mechanical behavior of the scaffolds was determined by tensile, compression, and three‐point flexural tests. It has been seen that 3%wt of HNT loading showed 124%, 145%, and 41% increments in tensile, compression, and three‐point flexural strength of the scaffolds, respectively. In‐vitro drug release and cell viability of the scaffolds were also examined. According to the cell viability result, a better cell proliferation regimen was achieved in all HNT‐containing groups without any cytotoxicity effect. Also, approximately 50% of the total drug was released from the scaffolds at the end of 120 h. Finally, it has been seen that the developed scaffolds show promise for bone regeneration and replacement of bone.

“…[9,10] Moreover, many literature works evidenced that the incorporation of nano-clay along with natural fibers in the polymers improved the mechanical properties and reduced the moisture absorption rate of the composites which created a new trend in the area of hybrid composites. [11,12] The defect-free surfaces (because of nanoscale size) and greater aspect ratio are the key factors that contribute to the enhancement of overall properties of hybrid composites. [9] Therefore, the hybrid composites prepared using natural fiber/nano-clay becomes an alternative to the hybrid composites fabricated using a combination of natural fibers and natural fiber/synthetic fiber.…”

The utilization of sustainable natural fibers as green filler/reinforcement material for producing polymeric composites is substantially improved due to increase in the perception of ecological safety and usage of biodegradable and renewable materials toward a green environment. These natural fibers are obtained from various sources and are reinforced in the polymer matrices to produce polymer matrix composites. However, the overall properties of these composites are low when compared to that of the synthetic fiber-based composites due to poor interfacial bonding between the hydrophilic natural fiber and hydrophobic polymers. This deficiency can be addressed by incorporating

“…Hybrid Polymer nanocomposites have received very much attention from nanoscience academics and industries due to their great physical, mechanical, and tribological properties. The addition of nano-sized inorganic fillers such as silica, titania, aluminium oxide, multiwall carbon nanotube, halloysite, nanoclay has reformed the mechanical and physical properties of the hybrid polymer composites extensively [8][9][10][11][12][13][14][15][16][17].…”

“…Among these methods, the mechanical properties are found to be high in autoclave method, but it is an expensive method of manufacturing. On the other hand, vacuum assisted resin infusion molding technique produces the polymer composite with similar mechanical properties like autoclave in a reasonable cost of manufacturing the polymer composite [17].…”

Reinforcement of epoxy-carbon-Kevlar fabric composite with the addition of nanosilica has resulted in the evolution of new hybrid polymer nanocomposite, which results in the improved mechanical properties of polymer hybrid nanocomposite. The current investigation concentrated on the dynamic mechanical behavior of unfilled and nanosilica filled carbon-Kevlar-epoxy polymer composite with five and four layers of carbon and Kevlar woven fibers respectively with epoxy matrix (5C4K). Nanosilica was mixed into the epoxy at different weight percentages (wt.%) of 0, 0.5, 1.0, and 1.5. The laminates were fabricated using the vacuum-assisted resin infusion moulding (VARIM) technique. The dynamic mechanical properties, storage modulus, loss modulus, damping factor (tan delta), and glass transition temperature was investigated using a dynamic-mechanical analyzer at temperature ranging from 25 to 165 degrees Celsius. The test specimens were prepared in accordance with the ASTM D4065 standard to investigate dynamic mechanical analysis (DMA) of the hybrid polymer nanocomposite. The results of the tested specimens for dynamic mechanical behaviors of carbon-Kevlar-epoxy hybrid nanocomposites are very much influenced by the presence of nanosilica. The storage modulus, loss modulus for nanosilica added hybrid polymer composites were more than the unfilled ones and the damping factor (tan delta) was observed more in an unfilled composite.
