Abstract: The present invention is related to a method for preparing biodegradable agro-waste fiber reinforced composite material for electric vehicle, Agricultural residues such as rice straw (RS) and sugarcane bagasse (SCB) are incorporated into a polylactic acid (PLA) matrix to form composite filaments through twin-screw extrusion. These filaments are used to fabricate 3D-printed components with optimized printing parameters. The resulting composites exhibit enhanced thermal insulation (up to 15.54% improvement over PLA), improved sound absorption, high electrical breakdown strength (up to 21.78 kV), and increased tensile modulus. The invention provides an environmentally friendly alternative to conventional synthetic materials, enabling the utilization of agro-waste while reducing material costs and environmental impact. The developed composites are suitable for use in electric vehicle interiors and other industrial applications requiring thermal, acoustic, and electrical insulation along with moderate mechanical performance.
