“…This subsequently increases the tensile strength and stiffness of kenaf fabric composites. The observed results were in good agreement with other research work involving bamboo fiber/epoxy/fly-ash hybrid composites [24] and jute fiber/epoxy/fly-ash particulate composites [25]. However, the tensile properties decreased beyond 10% of fly ash addition.…”

“…Therefore, it is important to ascertain the limitation of fly ash concentration for its effective usage to get the desired properties. However, there were very few research works [24,25] which examined the effect of fly ash on mechanical properties of hybrid polymer composites. This study is focused on the hybridization of kenaf/glass fabric with the addition of fly ash fillers to enhance the desired tensile properties of the green composite by reducing the synthetic fiber usage and encourage the natural materials consumption.…”

Economic and environmental concerns lead the researchers toward development of sustainable and renewable materials of which reinforced composites are part of. The abundantly available natural fibers have attracted the researchers to study their performance as reinforcements and feasibility for making automobile components. The performance of composite materials is mainly assessed through their mechanical properties. However, natural fibers to date were mainly used as reinforcements to create bulk composite components with reduced cost rather than improved mechanical performances. Among the methods available for improving mechanical properties of the natural fiber composites, combined mercerization treatment, hybridization, and incorporation of fly ash fillers in the matrix are the best solutions. Therefore, the objective of this research is to evaluate the tensile properties of hybrid kenaf/glass composites with and without fly ash particulate filler as per ASTM standards. Moisture absorption behavior and its effect on the tensile properties of hybrid composites are also investigated. The results revealed that the addition of 10wt % fly ash particles with natural fiber composites increased the tensile strength of composites while hybridization with glass fibers reduced the water absorption properties.

“…It is a unique class of filler suitable for polymer matrix because of its fine dispersion, homogeneity, inertness, low water absorption and chemical stability. There are several instances of investigation of mechanical properties of cenosphere-filled polymer composites [13][14][15][16][17][18][19][20].…”

Cenosphere is a ceramic-rich industrial waste produced during burning of coal in thermal power plants. This study deals with the effect of cenosphere as particulate filler on mechanical behaviour of woven jute-glass hybrid composites. The hybrid composite consists of jute and glass fiber as reinforcement and epoxy as matrix. The conventional hand lay-up technique is used to prepare composite specimens. Cenosphere of different weight percentage (5, 10, 15 and 20 wt%) was added to the hybrid composite. The samples were tested as per ASTM standards for their mechanical and flexural properties to establish the effect of filler content. It is found that the mechanical properties are significantly influenced by addition of waste ceramic filler cenosphere up to 15 wt% and increases the tensile, flexural and interlaminar shear strength by 90.47%, 24.32% and 16.75%, respectively, in comparison to unfilled composite. The morphologies of the composites studied by scanning electron microscope indicate good dispersibility of cenosphere in the matrix, which in turn improves the strengths appreciable.

“…To improve the mechanical properties, several studies have focused on altering the surface energy of natural fibers in order to modify the adhesiveness between the fiber and thermoset matrix. There have been numerous examples where the particle fillers in composites are treated with silane before incorporation into polymer matrices [8][9][10][11][12][13][14][15]. The dispersion aids, modifiers, or other additives were shown to influence the processing and the final mechanical properties of the materials.…”

Two different thermoset biocomposite systems are experimented in this study with the hope to improve their mechanical properties. Fiberglass and hemp, in form of fabrics, are used to reinforce the thermoset polymer matrix, which includes a traditional epoxy resin and a linseed oil-based bioresin (UVL). The fiber/polymer matrix interface is modified using two different approaches: adding a plant-based oil (pine or linseed) to the polymer matrix or coating the fibers with 3-(aminopropyl)triethoxysilane (APTES) prior to integrating them into the polymer matrix. Epoxy resin is cured using an amine-based initiator, whereas UVL resin is cured under ultraviolet light. Results show that hemp fibers with APTES prime coat used in either epoxy or UVL matrix exhibit some potential improvements in the composite’s mechanical properties including tensile strength, modulus of elasticity, and ductility. It is also found that adding oil to the epoxy matrix reinforced with fiberglass mostly improves the material’s modulus of elasticity while maintaining its tensile strength and ductility. However, adding oil to the epoxy matrix reinforced with hemp doubles the material’s ductility while slightly reducing its tensile strength and modulus of elasticity.
