“…Rice husk, which is an agricultural waste, has been successfully valorized as a filler in various polymer composites. Through additional treatments, rice husk filler use has improved the electrical insulating properties of epoxy-based composites [32]. Natural fillers have also been successfully incorporated not only in thermoset matrices but also in thermoplastic matrices.…”

Banyan aerial root (BAR) powder was prepared from the aerial roots of a Banyan tree to modify epoxy resin using a magnetic stirrer. The modification was performed at different proportions of BAR powder, namely, 2%, 4%, 6%, and 8%, by weight. Composites were fabricated with modified and unmodified resins using a combination of hand lay-up and compression molding processes to evaluate the influence of BAR powders on their mechanical properties. The test results showed that BAR powder incorporation had a positive influence on the mechanical properties of the composites, as an increase in tensile, flexural, and impact strengths was observed, with the highest tensile and flexural properties of 407.81 MPa and 339 MPa, respectively, seen in composites with 4% BAR and the highest impact strength 194.02 kJ/m2 observed in the specimen with 6% BAR powder. Though the properties saw a dipping trend at higher weight proportions of the particulate, they were still significantly higher than the properties of laminates prepared with unmodified resin. Gravimetric analysis and Fourier transform infrared spectroscopy (FTIR) on BAR powders confirmed cellulose to be the major constituent, followed by lignin and hemicellulose. A scanning electron microscope was used for studying the failure mechanisms of the laminates.

“…The dielectric constant is decreased in banana fibre composites due to surface modification [17,18]. The dielectric properties of banana fibre reinforced with polymers are studied and samples are prepared with the resin moulding method [19]. The dielectric properties are increased with the increasing fibre loading, such as dielectric constant, loss factor, and depreciation factor, at different frequency levels.…”

In this study, the electrical properties of banana leaf fibre-reinforced epoxy resin composites such as dielectric properties, dielectric constant, dissipation factor, and loss factor are tested at various frequencies and temperatures. At frequencies ranging from 1 to 10 kHz and temperatures ranging from 30 to 150o C, the dielectric properties of several composites containing banana leaf fibre are studied. The composite dielectric properties is gradually increased with temperature and decreased with frequency. Correspondingly, the mechanical tests involving a banana leaf fibre epoxy composite are conducted for tensile, bending, impact, and water absorption. The banana leaf fibre has been treated with a 5% sodium hydroxide (NaOH) solution to increase its dielectric and mechanical strength. According to this study, the mechanical strength of bio composites containing up to 60% TBLFE is greater than that of pure epoxy. A thermo gravimetric investigation of composites reinforced with banana fibres has revealed remarkable thermal stability up to 220o C. In a composite made from chemically treated banana fibre pressboard, there is a good bond between the fibres and the matrix. The FESEM surface analysis shows that treated banana leaf fibril insulation boards have a better texture than composites that have not been treated.
