Abstract

L'invention concerne un dispositif de stratification (100) construit en plusieurs couches et comprenant un produit stratifié (110) durci avec une résine, avec une couche d'absorption (120) destinée à recevoir une résine fluide, le dessous de la couche d'absorption (120) étant séparé d'une surface du produit stratifié (110) par une couche de séparation (130) et la surface de la couche d'absorption (120) éloignée du produit stratifié (110) étant masquée par une couche de revêtement (140) sensiblement étanche aux gaz. L'invention vise à permettre la fabrication d'un produit stratifié (110) présentant également des parties de surfaces fortement courbées. A cet effet, un ou plusieurs dispositifs de guidage de la résine (150) au niveau de la surface de la couche d'absorption (120) sont des canaux de résine (154), constitués d'espaceurs (151) de forme sensiblement stable et présentant une surface supérieure (152) et une surface inférieure (153), laquelle surface inférieure (153) est au moins en partie contiguë avec la surface de la couche d'absorption (120).
