“…This was expected as the tensile strength of glass fiber epoxy composites is higher than the compressive one which leads to the initial failure occurring on the top side under compression, however, light traction failure on the bottom face was also observed. 24 A mixed mode between compressive (top) and traction (bottom) failures were observed for the HG-3%, HJ-1%, and HJ-3% cases (see Figure 8(c-e)). This is likely due to the brittle failure of the natural core, similar to the J-0 case.…”

“…This can be explained by the fact that the synthetic nanofiller presented superior interfacial adhesion between fiber and matrix (see Figure 9). Prasob et al, 24 showed that the surface area of nanofillers influences the fiber/matrix interaction, in addition to the energy absorption by the composites. If we compare the impact resistance as a function of filler content, a significant variation of impact resistance can be observed between 1% and 3% filler content reinforced composites.…”

“…Saba et al 23 investigated the effect of addition of nano oil palm filler in a kenaf based epoxy composite and found significant improvements on the mechanical properties of the composite without the addition of coupling agents or fiber treatments. Prasob and Sasikumar 24 studied the effect of ZnO and TiO 2 fillers in jute/epoxy composites and found that the mechanical properties of the composites were significantly improved by the addition of the fillers and that water absorption decreased with increasing filler content. The maximum increase in mechanical properties and reduction in moisture diffusion was found for the 4% TiO 2 case.…”

The main objective of this work was to investigate the effect of reinforcements at different scales on the mechanical properties of natural fiber-reinforced composites. Pure jute and interlaminar hybrid jute/glass fiber-reinforced polymer composites were fabricated. Different types of fillers in two weight fractions (1 and 3 wt. %) were used as second reinforcements in the hybrid jute/ glass composites. Tensile, flexural, and impact tests were performed. It was found that the macroscale inter-play hybridization significantly improved the mechanical properties of the pure jute fiber based composites. When the fillers are used as second hybridization, the modified composites presented higher mechanical properties when compared to pure jute composites. However, the effect of fillers on the mechanical properties of the hybrid composites presented various trends due to the interaction between several factors (i.e., particle scale, content, and nature), which cannot always be separated. Increasing the synthetic filler content improved the tensile properties of the filled hybrid composites, while increasing the natural filler content worsen the tensile properties. The flexural strength of the multiscale hybrid composites was improved, while the impact properties were negatively affected.

“…Nano and micro fillers contribute to toughening mechanisms by bridging micro-cracks and slowing down the crack initiation and crack growth. The average weight fraction required to enhance the composites’ toughness and mechanical properties is in the range of 0.1–10 wt % and 10–50 wt % for the nano and micro-fillers, respectively [ 195 , 196 , 197 , 198 ]. Recently, Zhang et al [ 199 ] reported robust laminated biocomposites with improved mechanical strength and toughness.…”

Bio-based composites are reinforced polymeric materials in which one of the matrix and reinforcement components or both are from bio-based origins. The biocomposite industry has recently drawn great attention for diverse applications, from household articles to automobiles. This is owing to their low cost, biodegradability, being lightweight, availability, and environmental concerns over synthetic and nonrenewable materials derived from limited resources like fossil fuel. The focus has slowly shifted from traditional biocomposite systems, including thermoplastic polymers reinforced with natural fibers, to more advanced systems called hybrid biocomposites. Hybridization of bio-based fibers/matrices and synthetic ones offers a new strategy to overcome the shortcomings of purely natural fibers or matrices. By incorporating two or more reinforcement types into a single composite, it is possible to not only maintain the advantages of both types but also alleviate some disadvantages of one type of reinforcement by another one. This approach leads to improvement of the mechanical and physical properties of biocomposites for extensive applications. The present review article intends to provide a general overview of selecting the materials to manufacture hybrid biocomposite systems with improved strength properties, water, and burning resistance in recent years.

“…[18,19] Some recent works have shown that the nanofillers can noticeably enhance the mechanical properties of FRPs. [20][21][22][23] The lack of scientific results about the utilization of nanoparticles-decorated graphene on fabrication of natural fibers-reinforced polymers was the driving force for the selection of this work. Therefore, this study aimed at investigating the mechanical properties of the multiscale GONPs/JF/EP and SiO 2 @GONPs/JF/EP composites subjected to the three-point bending and high-velocity impact tests.…”

In the current work, silica‐decorated graphene oxide (SiO2@GONPs) nanohybrids were used to reinforce the jute fiber/epoxy (JF/EP) composite. Tetraethylorthosilicate (TEOS) was utilized to prepare the SiO2@GONPs using a facial route. The results of Fourier‐transform infrared spectroscopy (FTIR), atomic force microscopy, and elemental X‐ray mapping confirmed the successful synthesis of SiO2@GONPs nanohybrids. Herein, the effects of SiO2@GONPs loading (0, 0.1, 0.3, and 0.5 wt%) on the mechanical behavior of the JF/EP composite were investigated with emphasis on the flexural and high‐velocity impact properties. The results revealed that reinforcement of matrix with 0.3 wt% SiO2@GONPs enhanced the flexural strength of the JF/EP composite by about 40%. The energy absorption capability and impact limit velocity of the 0.3 wt% SiO2@GONPs‐filled JF/EP composite were 61 and 28%, respectively, higher than those of the neat specimen. Compared to the untreated‐GONPs, the SiO2@GONPs nanohybrid demonstrated an evident superiority in improving the mechanical properties of the JF/EP composite at the same loading. Evaluation of the fracture surfaces of the multiscale composites revealed that the improved fiber‐matrix interfacial bonding was the basic mechanism of fracture in these specimens.
