Abstract

L'invention concerne une semelle de longeron composée d'une pluralité de tiges composites distinctes collées ensemble dans un moule pour former la semelle de longeron. L'invention concerne également un procédé de fabrication d'une semelle de longeron qui consiste à coller ensemble des tiges composites distinctes dans un moule, au moyen d'un agent de collage, pour former la semelle de longeron. De plus, l'invention concerne un système de production d'électricité qui comprend une installation d'éolienne conçue pour générer de l'électricité, l'éolienne comportant une pale, la pale présentant un longeron pourvu de semelles, et chaque semelle de longeron comprenant une pluralité de tiges composites pultrudées collées ensemble dans un moule pour former une semelle de longeron.
