Design and Analysis of Glass Fiber Reinforced Plastic Composite Rotor Blade

GFRP (Glass Fiber Reinforced Plastic) composite materials are used in many engineering applications because of its high strength to weight ratio. The purpose of this experiment is to investigate mechanical properties of GFRP rotor blades which are used in cooling towers. These blades are manufactured by pressure bag molding process by using suitable mould. Before installation (Delivery), the blade must be tested for mechanical properties. For this testing, GFRP laminate is made by hand layup technique. Epoxy resin is used as matrix in manufacturing of the GFRP laminate. Axial flow fans are large capacity air moving devices suitable for mine ventilations and air heat exchangers. The conventional cast aluminum blades have a complex design with a higher power consumption and lower performance efficiency. The aim of proposed work is to fabricate, design, and analyze the epoxy based glass fiber composite, compare these results with experimental and theoretical values.
