Abstract

L'invention concerne un procédé pour la fabrication d'une structure en résine renforcée par des fibres, comprenant : une étape dans laquelle une résine thermodurcissable est introduite dans une rainure d'un moule formé de manière à correspondre à la forme d'une structure supplémentaire et la résine thermodurcissable forme une structure supplémentaire semi-durcie, qui est dans un état semi-durci ; une étape dans laquelle une résine thermodurcissable constituant une résine renforcée par des fibres forme un corps principal semi-durci, qui est dans un état semi-durci ; une étape dans laquelle la structure supplémentaire semi-durcie dans la rainure du moule et le corps principal semi-durci sont pressés l'un contre l'autre et chauffés et les résines thermodurcissables de la structure supplémentaire semi-durcie et du corps principal semi-durci sont durcies de sorte que le corps principal est collé à la structure supplémentaire ; et une étape dans laquelle le moule est séparé de la structure supplémentaire.
