MECHANICAL CHARACTERIZATION OF RONIER WOOD FOR ITS USE IN THE DESIGN OF WINDMILL BLADES

Wind energy and the materials that support the production of this energy remain achallenge. The work carried out aims to verify the possibility of using BorassusAethiopum wood in the wind turbine industry. This study of this wood closely observes the resistance to weather, insects and its mechanical behavior in bending and its resistance in water and in the face of solar radiation. Immersion, three-point bending tests were carried out in the longitudinal direction of the fibers on the samples. Borassus is essentially composed of intertwined fibers, making it a very elastic material. Since wood is a material that does not withstand water, this book presents the behavior of Borassus in the face of water and the effects of sun radiation. Experimental surveys have evaluated the duration of absorption of this wood, as well as the simple bending test. Curves have been established by the Excel spreadsheet. The analysis of the different results showed that BorassusAethiopum wood has a compact structure of fibers, has good flexural strength and makes it resistant to the weather. Borassus wood may be well suited for wind turbine blades, but for wind turbines of nominal power not exceeding 7.097 kW.
