The superior inherent properties like low density, lower consumption of energy and low cost, when compared with synthetic fibers, some of the widely used natural fibers utilized for manufacturing composites include banana, hemp, jute, sisal, coir, and bamboo fibers. Apart from the mentioned advantages, unlike man-made fibers, natural fibers are biodegradable, abundantly available, renewable, and hence they are widely adopted for use. Current work focusses on preparing the polyester hybrid composites reinforced with banana and jute fibers. Composites were manufactured by compression molding technique; both the fibers were chemically modified using sodium hydroxide (NaOH) and potassium hydroxide (KOH) for 5% of solution concentrations about 48 hours before fabrication. Composites are investigated for impact, flexural, tensile and compression behaviors and the tests were carried out as per ASTM standards. Thermogravimetric analysis (TGA) is also carried out on the hybrid composites to evaluate their thermal properties. The influence of chemical treatments on the surface of reinforcements is evident by mechanical and physical characterization. In part of this, the fractography analysis is comprehensively examined by optical microscope as well as Scanning Electron Microscope (SEM) to determine the influence of chemical modification on composites. Finally, it is observed that jute and banana fiber hybridization can be a potential reinforcement for making low load-bearing fiber-reinforced polymer composite products.
