The drawn glass fiber reinforced plastic reinforced blades have good durability and corrosion resistance
Resistant to acid, alkali and atmospheric corrosion, no regular maintenance is required, the material is uniform, flexible and consistent size. Standard weight, smooth surface, etc.
Mainly used for: wind turbines, wind water pumps, highway anti-glare panels.
Most rotor blades on large wind turbines are made of glass fiber reinforced plastic (GRP). Using carbon fiber or aramid as reinforcement is another option, but such blades are not economical for large wind turbines. Wood, epoxy wood or epoxy-wood fiber composites are not yet present in the rotor blade market, although there are developments in this area. Steel and aluminum alloys present problems such as weight and fatigue respectivelymetal. They are currently only used in small wind turbines.
