NOVELTY - The wind turbine (70) component e.g. nacelle (72), wind turbine blade has a polymer substrate, and a metal plating layer plated on at least one of the interior surface and exterior surface of polymer substrate. The polymer substrate is formed from a thermoplastic material or a thermoset material by injection molding or compression molding. The polymer substrate has a thickness in the range of 1.3-13 millimeters.    USE - Wind turbine component e.g. nacelle, wind turbine blade for wind turbine (claimed) used for converting wind energy into mechanical energy. Uses include but are not limited to armed forces, power generation, research, medicine, and governmental agencies. Can also be used in nuclear waste equipment, submersible vehicles and desalination equipment, space satellites used for telecommunications, weather monitoring, navigation, research, and military applications, pulley used for lifting loads or applying forces in wide range of applications, impeller used in pumps and hydroelectric or hydropower applications, gears such as helical gears, spur gears, internal gears, rack and pinion gears, face gears, herringbone (double helical) gears, and bi-level gears, ball bearings, heating, ventilation, air conditioning, and refrigeration (HVACR) equipment, lift structures such as lift doors, lift walls, and hatches, robotic components.    ADVANTAGE - The lighter-weight construction of plated polymeric nacelle leads to reductions in costs for installation and/or repair of the nacelle. The plated polymeric wind turbine nacelle provides lightweight alternatives for existing wind turbine nacelles formed from heavier metallic frames. The lighter weight construction of plated polymeric nacelle leads to reductions in installation and manufacturing costs for wind turbine nacelles. The lightweight and high-strength construction of the plated polymeric blades lead to reductions in manufacturing costs and installation costs, as well as improvements in aerodynamic functions and impact resistance. The thickness of metallic plating layer in different areas of the blade is tailored to provide desired properties such as resistance against impact e.g. bird strike. The schedule savings are realized for the manufacture of plated polymeric blades due to high-throughput molding and plating processes.
