Abstract
Recent years have seen an increase in the use of natural fibers. Rice straw/natural fiber hybrid composites can recycle agricultural waste easily and eliminate fine silica ash pollution. Composite specimens are created by hand lay-up as per ASTM standards. Unsaturated polyester resins and rice straws are studied using scanning electron microscopy. Hybrid composites reinforced with rice straw and neem powder perform better. The optimal fiber content for impact and flexural strength is 50 % by volume fraction. RSNWP6 fibers with hybrid properties have more significant impact strength, hardness, and flexural strength than other fibers at 516.86 J/m, 45 BIU, and 80.03 MPa.
