Exploitation of the elastic behavior of Borassus in the development of wind blades

Abstract

Wind turbines have existed since ancient times and helped man accomplish various tasks. The essential organ is the blade allowing the energy of the wind to be transformed into desired energy. According to its role, the choice of material for its manufacture was the subject of several researches because of the expected weight and the multiple demands. Although wood in general was refuted because of its degradation, borassus remains tenacious in the face of bad weather and various stresses. Several material resistance tests carried out on borassus specimens showed its elasticity, proof of its usability in the production of wind turbine blades. The absence of knots and the fact that borassus cannot be attacked give reason to the choice of borassus in wind turbines. The object of this work is to present the borassus, little known but having more values, in the three-way bending solicitation where the linear zone is exploited.
