Abstract
Due to the high effective loading acting on wind turbines, it is preferred to be manufactured from high strength steel to withstand the applied wind stresses. Therefore, the experimental work performed in this study has focused on some steel specimens coated with different types of fibrous materials as; glass, carbon, and Kevlar fibers. The performances of these fibrous coatings have been compared with hard chrome coating.The coated steel samples have been exposed to various environmental factors as; erosion and hot corrosion followed by mechanical testing.The results of this work showed that the hard chrome coating could not so bear weather factors that is not suited to protect the wind turbine blades.Whereas; the CRP (Carbon Reinforced Polyester) (CRP) coating has shown a good ability to withstand the different environmental effects.This appropriate composite material has been verified through some experimental testing to verify its design safety under different environmental loads applied on wind blades, and CRP could enhance the performance of the wind blades more than the other types of composite materials
