Abstract: The present invention relates to a high-performance windshield washer pump impeller for automotive applications, manufactured from a polycarbonate (PC) composite reinforced with graphene. The incorporation of graphene into the PC matrix significantly enhances the rotational efficiency of the impeller by reducing friction between moving components, resulting in smoother operation, lower energy consumption, and improved pump performance. The PC base material provides superior chemical resistance against automotive fluids, including windshield washer solutions, detergents, and other water-based additives, preventing material degradation, swelling, or corrosion during long-term operation. The impeller is designed with optimized blade geometry and structural features to maximize fluid flow, minimize turbulence, and reduce vibration, further enhancing the reliability and efficiency of the windshield washer system. The combination of graphene reinforcement and PC matrix ensures high mechanical strength, durability, and extended service life, even under harsh operating conditions such as high temperature fluctuations, continuous rotational cycles, and exposure to chemically aggressive fluids. The invention can be manufactured using cost-effective methods such as injection moulding or precision moulding, enabling consistent dimensional accuracy, reproducibility, and scalability for mass production. This novel impeller addresses the limitations of conventional polymer-based impellers by simultaneously offering enhanced chemical resistance, low-friction operation, mechanical toughness, and prolonged operational lifespan. It provides an efficient, durable, and reliable solution for modern automotive windshield washer systems, contributing to improved vehicle safety and reduced maintenance requirements.
