Abstract

L'invention concerne un complexe textile (1) destiné à être intégré dans la structure d'une pièce moulée réalisée par infusion de résine.Ce complexe associe :• au moins une couche d'une structure textile de renfort (2) ;• au moins une couche drainante (3) formée d'une structure ajourée, apte à former une zone de passage préférentiel de la résine lors de l'infusion. Cette couche drainante demeure dans la pièce moulée après infusion.Ces couches de renfort (2) et de drainage (3) sont mécaniquement solidaires, de sorte que le complexe reste déformable.
