Abstract

L'invention concerne un procédé de fabrication de pales de turbines éoliennes. Ce procédé consiste à enrouler des matières fibreuses composites sur un mandrin pour former le surface portante désirée. Au cours du processus d'enroulement, les fibres doivent toujours être maintenues en contact avec la surface du mandrin. Si cette surface est concave, les fibres doivent enjamber cette dernière en créant ainsi un vide par dessous. L'invention est utilisée pour éviter cet enjambement et empêcher ainsi la formation de vides qui affaiblissent la structure de la paleThe invention relates to a method of manufacturing wind turbine blades. This process involves winding composite fibrous materials on a mandrel to form the desired airfoil. During the winding process, the fibers should always be kept in contact with the surface of the mandrel. If this surface is concave, the fibers must span it, thus creating a vacuum from below. The invention is used to avoid this spanning and thus prevent the formation of voids which weaken the structure of the blade.
