Composite Materials Used as Lightweight Material for Ceiling Fan Blades

Ceiling fans are widely used in tropical and developing countries for thermal comfort due to their low cost and low energy consumption. Conventional ceiling fan blades are manufactured using metals such as aluminium or mild steel, which increase weight, power consumption, and vibration during operation. Recently, composite materials have gained attention as alternative lightweight materials for fan blade manufacturing because of their high strength-to-weight ratio, corrosion resistance, and design flexibility. This paper investigates the suitability of fiber reinforced composite materials such as Glass Fiber Reinforced Polymer (GFRP) and Carbon Fiber Reinforced Polymer (CFRP) for ceiling fan blades. Mechanical properties such as tensile strength, flexural strength, impact resistance, and vibration characteristics are reviewed and compared with conventional metal blades. Experimental and analytical results indicate that composite fan blades significantly reduce weight and power consumption while improving aerodynamic efficiency and durability. The study concludes that composite materials provide an effective solution for lightweight and energy-efficient ceiling fan blade design.
