Description
Summary:Natural fibres are less expensive than other types of fibre, the greatest replacement for synthetic fibre composites today is a natural fibre reinforced biodegradable composite. For uses in domestic goods, natural fibres like sisal, kenaf, plam, banana, jute, and coir have been employed as reinforcement in polymer composites. At the moment, research into composite materials is focused on employing natural fibres rather than synthetic ones. When used as reinforcing fibres in matrices, natural fibres made from yearly renewable resources have a positive impact on the environment in terms of final disposal and raw material use. Because of their low density, superior mechanical performance, universal availability, and disposability, natural fibres provide an alternative to technical reinforcing fibres. Chemically altering the fibre surface can strengthen the bond between the fibre and matrix. The fibre surface can be cleaned, chemically modified, and given a rougher finish through chemical treatment. Scanning electron microscopy was used to investigate surface analyses on fibre for before and after treatment. The banana fibre's stress-strain curve is identified. As a function of fibre diameter, test length, and testing speed, properties like initial modulus (YM), ultimate tensile strength (UTS), and percentage elongation are assessed. The failure is caused by the pullout of microfibrils along with the tearing of cell walls, according to scanning electron microscopy (SEM) investigations of the broken surfaces of these fibres; the likelihood for fibre pull-out appears to diminish with increasing testing speed.
