Reducing vehicle emissions and fuel consumption remains a primary challenge for the automotive industry. Using lightweight materials such as Aluminum Metal Matrix Composites (AMMCs) reinforced with Coconut Shell Ash (CSA) offers an eco-friendly and cost-effective solution. This study investigates the optimization of tribological properties, including wear resistance and hardness, of AMMCs using the Response Surface Methodology (RSM). Various composite samples containing 10% and 20% CSA by weight were prepared using powder metallurgy, and tribological tests were performed using a pin-on-disc wear testing machine. The results demonstrate a significant improvement in wear resistance and hardness with increasing CSA content. The wear parameters were optimized, achieving a minimum wear loss of 0.001113 g. This research contributes to the development of sustainable, lightweight materials suitable for automotive and aerospace applications.
