Abstract[English]
According to the present invention there is provided a method of reconditioning a composite body (10) comprising at least one layer of reinforcing material (12) embedded in a thermoset epoxy matrix (14) having a crosslinked network structure. The method comprises identifying a region (16) of the composite body (10) for reconditioning; arranging a temporary barrier (18) on a surface of the composite body (10) to define an application area (22) comprising the identified region (16).The method further comprises applying a dissociation fluid (24) to the surface of the composite body (10) in the application area (22) to at least partially degrade the thermoset epoxy matrix (14) in the application area (22) to thereby dissociate one or more layers of reinforcing material (12) from the thermoset epoxy matrix (14).[French]
La présente invention concerne une méthode de reconditionnement d'un corps composite (10) comprenant au moins une couche de matériau de renforcement (12) incorporée dans une matrice époxy thermodurcie (14) ayant une structure de réseau réticulé. La méthode comprend l'identification d'une région (16) du corps composite (10) pour le reconditionnement ; l'agencement d'une barrière temporaire (18) sur une surface du corps composite (10) pour définir une zone d'application (22) comprenant la région identifiée (16). La méthode comprend en outre l'application d'un fluide de dissociation (24) à la surface du corps composite (10) dans la zone d'application (22) pour dégrader au moins partiellement la matrice époxy thermodurcie (14) dans la zone d'application (22) pour ainsi dissocier une ou plusieurs couches de matériau de renforcement (12) de la matrice époxy thermodurcie (14).
