Mechanical Performance of Biofiber/Glass-reinforced Epoxy Hybrid Composites

Abstract

The degree of mechanical reinforcement that can be obtained by the introduction of glass fibers in biofiber (silk fabric)-reinforced epoxy composites has been assessed experimentally. The addition of a relatively small amount of glass fabric to the silk fabric reinforced epoxy matrix enhances the mechanical properties of the resulting hybrid composites. It has also been observed that the properties increase with the increase in the weight fraction of reinforcement content to the maximum extent. The water uptakes of hybrid composites are observed to be less than that of unhybridized composites.

“…A remarkable reduction in the void content of hybrid composites in different layering patterns and a slight increase in tensile property were observed for the composite with jute as the skin and palm oil EFB as the core material. Padma Priya and Rai [3] experimentally analyzed the degree of mechanical reinforcement that could be obtained by the introduction of glass fibers in biofiber (silk fabric)-reinforced epoxy composites. The addition of a small amount of glass fabric to the silk fabric-reinforced epoxy matrix enhances the mechanical properties of the resulting hybrid composites.…”

Effect of Moisture Absorption Behavior on Mechanical Properties of Basalt Fibre Reinforced Polymer Matrix Composites

“…The decrease of water absorption in epoxy is attributed to the increasing of tortuosity path for water penetration in the epoxy composites by the hybrid of glass fiber and OMMT [6]. The water uptakes of hybrid composites are observed to be less than that of unhybridized composites [7]. The basalt fibre composites were manufactured with and without the Gel-coating process and were immersed in a moisture absorption device at 80 ∘ C for more than 100 days.…”

Review of natural fibre-reinforced hybrid composites

“…Hand layup is a simple technique which has been employed to make thermoset composites. Because of its simplicity, hand layup has been widely used for making hybrid E glass/flax/epoxy composites 67 , silk/glass fabric reinforced epoxy hybrid composites 73 , banana/flax based natural fibre epoxy composites 83 , curaua/glass polyester hybrid composites 66 , jute fibre (Hessian cloth) and E glass fibre (mat) reinforced unsaturated polyester (USP) composites 41 , untreated (as received) woven jute and glass fabric reinforced isothalic polyester composites 42,43,70 , unsaturated polyester based sisal/glass hybrid composites 53,61 , woven banana fibre, kenaf fibre and banana/kenaf fibre polyester hybrid composites 87 , silk/sisal fibre reinforced unsaturated polyester based hybrid composites 106 , and sisal/jute/glass fibre reinforced polyester composites 104,105 .…”
