The recent development of natural fiber-reinforced polymer composites have shown innumerable economic and environmental benefits for a vast array of engineering applications. It is quintessential to investigate the effect of water absorption on the composites that remain in the water for a maximum of their intended service period. This study is an effort in this direction that investigates the effect of water absorption on thermo-mechanical properties of flaxhemp-reinforced epoxy composites fabricated using compression hand layup technique with different weight fraction of fiber. The fabricated composites have been characterized physically (density and water absorption), thermomechanically (tensile, flexural, thermal conductivity, and dynamical mechanical analysis), and morphologically (scanning electron microscopy [SEM]). The analysis revealed that hemp-reinforced composites (S1) had the highest water absorption capabilities in comparison to the flax-reinforced composites (S5).Higher water absorption capability had an adverse effect on the mechanical properties of fabricated composites. However, hybrid composites (S2, S3, and S4) reported better performance with regard to S1. The increased water content, however, increased the thermal conductivity of composites and maximum has been revealed for S1 (0.82 W/mK) and minimum for S5 (0.48 W/mK). The water molecules showed detrimental effects on the viscoelastic properties and revealed S3 have better interlocking bond with the lowest reduction in storage modulus (12%) and glass transition temperature (4 C) in comparison to S1 (30%) under wet conditions. A comparative analysis of the thermo-mechanical properties was also made for developed composites under dry, saturated, and re-dried conditions. The SEM has been used to characterize the morphological and fracture behavior of the fabricated composites under the influence of water uptake. The effects of water molecules on the hygrothermal aging index and diffusion co-efficient have also been discussed. Overall, the hybridization of

“…Fig, 3(d) showed the microstructure behavior of TiO2 nanoparticles and analyzed that, the microscopic view of nanoparticles tends to spherical shape. The spherical shapes of nanoparticles have a positive impact on the thermo-mechanical properties of developed nanocomposites and also help to enhance the interfacial bond between reinforcement and matrix materials [43,44].…”

“…These nanoparticles create obstacles at the crack front and result in crack front bowing in the middle of nanoparticles. This may lead to creating secondary crack which results in increments of fracture toughness and fracture energy [44]. But for higher weight fraction of TiO2 nanoparticles, the bonding strength decreased rapidly due to agglomeration of nanoparticles that reduce the homogeneity and effective weight fraction of nanoparticles.…”

The incorporated of inorganic nanoparticles with thermosetting epoxy polymer are an emerging field of research over past few years. It is well analyzed that epoxy matrix are brittle in nature that shows poor crack initiation and propagation and results poor thermo-mechanical properties.Therefore, researchers are showing their interest towards nanoparticles embedded epoxy composites to improve their fracture resistance (brittleness and toughness). In this investigation, the dispersion of TiO2 nanoparticles at different weight fraction (0-2%) with glass fiber reinforced epoxy composites is performed to enhance structural and thermo-mechanical properties. The TiO2 nanoparticles are prepared by sol-gel method and structural analysis of TiO2 nanoparticles shows greater interfacial bond with epoxy matrix and glass fibers due to fine dispersion of nanoparticles. From obtained results, a significant enhancement in their tensile strength (38.56%), flexural strength (30.52%), inter-laminar shear stress (25.22%), impact strength (327.10%), micro-hardness (48.53%) and fracture energy (40.19%) with minimum detrimental effect on toughness was revealed for GFRP-T1.0 compare to GFRP-T0.0 composite laminates. The stiffness and rigidity also improved up to 52.72% and 34.13% respectively for GFRP-T1.5 compare to GFRP-T0.0 composite laminates. The effects of nanoparticles contents and clustering size on thermal stability and glass transition temperature of developed composites are observed by thermo-gravimetric analysis. The surface morphology of TiO2 nanoparticles are characterized by transmission electron microscope (TEM) while dispersion of nanoparticles and failure of developed composites were analyzed by scanning electron microscopy (SEM).

“…The incorporation of marble particles into the polypropylene matrix led to the increase of tensile and flexural strength. Areca nut [ 42 ], banana crop residues [ 61 ], grains from distillery [ 62 ], sugarcane bagasse [ 63 ], sunflower husk wastes [ 64 ], pineapple leaves [ 65 ] or woof flour [ 66 ] have been proposed in the literature as a way to obtain sustainable composites from agro-industrial wastes, to just cite a few examples.…”

“…Kirsh and Chutkina achieved similar results when adding several agricultural residues (cocoa and rice husks or beet pulp) to a PE matrix, finding that the mechanical properties were drastically reduced after composting [ 97 ]. Finally, Saha, Kumar and Kumar have studied the performance of epoxy composites containing pineapple fibers, including biodegradability assays [ 65 ]; for these tests, test bars are subjected to a bacteria suspension for 45 days, and the weight of the samples is taken as a measurement of the biodegradation extent. Results show similar conclusions to those observed in other studies, with increased the biodegradability when introducing a higher ratio of pineapple fibers.…”

Are Natural-Based Composites Sustainable?

This paper assesses the aspects related to sustainability of polymer composites, focusing on the two main components of a composite, the matrix and the reinforcement/filler. Most studies analyzed deals with the assessment of the composite performance, but not much attention has been paid to the life cycle assessment (LCA), biodegradation or recyclability of these materials, even in those papers containing the terms “sustainable” (or its derivate words), “green” or “eco”. Many papers claim about the sustainable or renewable character of natural fiber composites, although, again, analysis about recyclability, biodegradation or carbon footprint determination of these materials have not been studied in detail. More studies focusing on the assessment of these composites are needed in order to clarify their potential environmental benefits when compared to other types of composites, which include compounds not obtained from biological resources. LCA methodology has only been applied to some case studies, finding enhanced environmental behavior for natural fiber composites when compared to synthetic ones, also showing the potential benefits of using recycled carbon or glass fibers. Biodegradable composites are considered of lesser interest to recyclable ones, as they allow for a higher profitability of the resources. Finally, it is interesting to highlight the enormous potential of waste as raw material for composite production, both for the matrix and the filler/reinforcement; these have two main benefits: no resources are used for their growth (in the case of biological materials), and fewer residues need to be disposed.
