A wind turbine blades modeling study is so critical because of their design, as we all know, domestic wind turbine blades are usually designed using aluminum alloy and glass fiber. In this paper we are going to study the resistance of a new natural composite material based on hemp fiber and an Epoxy matrix, for that we had conceived a three-dimensional model of the blade using aerodynamic profile parameters and geometric parameters on SolidWorks modeling software. Then, the model was imported into the ANSYS Workbench to perform a static, modal and harmonic analysis using FEM. The results were compared between the three materials; this comparative study shows that there is a good agreement between the three materials under stress. And for natural frequencies, the hemp fiber composite blade has higher natural frequencies than the aluminum alloy blade and the glass composite blade with a large standard deviation. For harmonic response, results show that the blade operates stably under resonance conditions, resonance does not occur and the composite hemp fiber blade functions safely
