“…A matrix holds all of the reinforcing fibers and agents together in a composite to transfer/share any external stress within the constituents for providing protection against any degradative processes, either in a mechanical (impact damage, delamination, high temperature, creep, and water absorption) or chemical form. The matrix is also termed a base material, and plays a critical role in composites carrying tensile loads in the structure [100,101]. There are four important matrix types: (1) metallic, (2) polymeric, (3) carbon, and (4) ceramic.…”

Composite materials reinforced with biofibers and nanomaterials are becoming considerably popular, especially for their light weight, strength, exceptional stiffness, flexural rigidity, damping property, longevity, corrosion, biodegradability, antibacterial, and fire-resistant properties. Beside the traditional thermoplastic and thermosetting polymers, nanoparticles are also receiving attention in terms of their potential to improve the functionality and mechanical performances of biocomposites. These remarkable characteristics have made nanobiocomposite materials convenient to apply in aerospace, mechanical, construction, automotive, marine, medical, packaging, and furniture industries, through providing environmental sustainability. Nanoparticles (TiO2, carbon nanotube, rGO, ZnO, and SiO2) are easily compatible with other ingredients (matrix polymer and biofibers) and can thus form nanobiocomposites. Nanobiocomposites are exhibiting a higher market volume with the expansion of new technology and green approaches for utilizing biofibers. The performances of nanobiocomposites depend on the manufacturing processes, types of biofibers used, and the matrix polymer (resin). An overview of different natural fibers (vegetable/plants), nanomaterials, biocomposites, nanobiocomposites, and manufacturing methods are discussed in the context of potential application in this review.

“…Due to the low susceptibility to moisture, higher mechanical strength, reduced manufacturing cost, and improved electrical insulating properties, E-glass fibers are considered as a useful reinforcement to polymer composites as observed in the studies reported by Vijay Kumar and co-authors. [4] The studies of Amal Nassar and co-authors [5] have revealed the significance of hybrid fillers, which combines the good characteristics of both the micron-and nano-sized fillers. The principle of hybrid fillers is that the one filler can enhance the characteristics which are limited by the presence of the other filler due to synergistic effects.…”

Reinforcement of epoxy glass fabric composites with nano-and micro-fillers has resulted in the development of polymer composites with good electrical, thermal, and mechanical properties. The present work attempts to estimate the impact of hybrid fillers on dynamic-mechanical properties of the epoxy composites with a different filler. The dynamic mechanical parameters such as storage modulus, loss modulus, and damping factor over a temperature of 25 C-250 C have been investigated. The viscoelastic properties of composites are also confirmed with a Cole-Cole plot. From the results, the storage modulus of the composites is observed to lie in the range of 8000 to 12,500 MPa, and the epoxy composite with silicon carbide filler shows the highest storage modulus. Composite with 5 wt% of alumina shows the maximum loss modulus of 2100 MPa. The glass transition temperature of the base epoxy composite is 135 C and it increases to 137 C with the incorporation of hybrid cenosphere and molybdenum sulfide fillers. The storage modulus shows only marginal differences as compared to their counterparts with nanofillers but is higher by about 10-15% in comparison to the micron filler-based composites. However, the differences in the loss modulus of the nanocomposites, hybrid composites, and the composites with micron-sized filler are not significant.

“…In details, the decrement of GNP nanocomposites was recorded about 9%, 23%, 26%, 31%, and 49% for 0.2 wt%, 0.4 wt%, 0.6 wt%, 0.8 wt%, and 1.0 wt% loading of GNP, respectively. It is interesting to note that this result showed a little variation as compared to the previous research of epoxy resin/GNP nanocomposites which reported the increase in impact strength for low GNP loading and further decrement for higher GNP (~0.5 wt% and above 3,15 ) loading. As reported in the literature, the increase in impact strength can be explained by the micro‐plastic deformation occurring around the GNP 7 .…”

“…Numerous studies have been carried on pure epoxy resin reinforced with raw 6,7,15,16 or modified GNP 3,17 in the range of 0.1–3 wt%. Despite of these studies, the investigation of GNP reinforcement into the rubber‐modified epoxy was very few 8,14 .…”

In this study, graphene nanoplatelets (GNP) of 0.2%–1.0% by weight were introduced to the rubber toughened epoxy matrix with via a direct method. The effect of GNP loadings on the mechanical (tensile and impact properties) and thermal properties of the rubber toughened epoxy/GNP nanocomposites were evaluated. The results showed that the incorporation of GNP had optimally improved the tensile strength and tensile modulus by 70% and 74%, respectively, at 0.6 wt% filler loading. Thermogravimetric analysis (TGA) and Tg increment result proved the barrier effect via delaying decomposition process which induced by the layered structure of GNP and thus significantly enhanced the thermal stability of epoxy‐based resin, irrespective of GNP loadings (insignificant difference in the decomposition temperature). The fractured surfaces of these nanocomposites showed the good interfacial interaction between the matrix and the GNP nanofiller. X‐ray diffraction (XRD) analysis demonstrated the exfoliation and intercalation states of GNP dispersion in epoxy/LENR.
