PURPOSE: An FRP(Fiber-Reinforced Plastic) fan is provided to prevent the loss of primary junction parts because the bonding strength of the front curved part, where the resistance of air and vapor flow is concentrically applied, is reinforced with a reinforcing sheet. CONSTITUTION: An FRP fan comprises a fan body(20), a reinforcing sheet(30), and a groove. The fan body comprises a top plate(22) and a bottom plate(24) which are made of glass fiber sheets with adhesive resin and attached together so that the fan body has a streamlined cross-section. The reinforcing sheet is attached to cover the front curved part of the fan body and support the bonding strength at the junction of the top and bottom plates. The groove is formed in the front curved part of the fan body in order to receive the reinforcing sheet.
