This study investigates the mechanical and machining properties of Silicon Carbide (SiC) composites reinforced with natural fibers. SiC is valued for its high strength and hardness but suffers from brittleness and poor machinability. Natural fibers, known for their lightweight and eco-friendliness, are incorporated into SiC matrices to enhance its properties. Mechanical tests, including tensile and flexural strength, and hardness evaluations were conducted on SiC-natural fiber composites. Machining tests examined cutting performance under various conditions. Results indicate significant improvements in mechanical properties with natural fiber reinforcement, including enhanced tensile and flexural strength and increased hardness, indicating improved wear resistance. Machining tests demonstrate enhanced machinability compared to pure SiC, with reduced tool wear and improved surface finish under specific conditions. This study highlights the potential of natural fiber reinforcement to enhance the mechanical properties and machinability of SiC, promoting its use across industries while fostering sustainability through the adoption of eco-friendly materials.
