MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202641068395 A) filed by Saveetha Institute Of Medical And Technical Sciences on June 01, 2026, for Radiator Fan Blade Formed From A Fiber Reinforced Polymer Composite For Automotive Cooling Systems.
Inventors include R. Endymion Grosious; Dr. L. Natrayan; and Dr Ramya Mohan.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: The present invention relates to a radiator fan blade manufactured using a basalt fibre reinforced polycarbonate composite material. Traditional fan blades made from polypropylene, ABS, or unreinforced polymers often exhibit limited fatigue strength, poor heat tolerance, and higher rotational inertia, leading to decreased cooling efficiency and premature mechanical failure under high-speed operation. The proposed invention utilizes a polycarbonate matrix strengthened with basalt fibres, providing superior fatigue resistance, improved thermal stability, and significantly reduced inertia due to its lightweight construction. The composite fan blade maintains structural integrity under continuous rotation, engine bay heat, and aerodynamic loading, ensuring stable performance and extended service life. By combining advanced composite material properties with optimized blade geometry, the invention delivers a durable, heat-resistant, and energy-efficient radiator fan solution suitable for modem automotive cooling systemsvides a ra
