Abstract
The uses of the cellulosic fibers in the natural fiber reinforced polymer composites (NFC) for constructing a wind turbine blade structure will be evaluated in the present work through experimental study. The blade shape designed according to the local wind characteristics on the Tabuk city in Saudi Arabia. The blade mechanical resistance identifies, according to the different forces applied to wind turbine blades. The palm cellulosic fibers were used as reinforcement Those fibers were prepared through mechanical and chemical extraction process. The extraction was through mechanical decomposition in thin fibers and chemical extraction method by chloride and alkaline. To evaluate the reinforcement effect on wind turbine blades a horizontal wind turbine was constructed. The palm natural fibers used as reinforcement of blades with resinepoxy gives an encouraging result in the sense of robustness and efficiency. The uses of NFC based on cellulosic fibers for constructing wind turbine blades can be considered as a potential candidate for the manufacturing of total recycling wind turbine blades from natural fibers.
