(FR) DISPOSITIF D’INDICATION ET PROCÉDÉ DE SURVEILLANCE DE L’INTÉGRITÉ STRUCTURELLE D’UN SITE DE RÉPARATION
Abstract
(DE)
Es wird eine Anzeigevorrichtung zum Überwachen der strukturellen Integrität einer Reparaturstelle an einer aus einem Verbundmaterial gefertigten Laminatstruktur eines Teils einer Luftfahrzeugaußenhaut angegeben. Die Anzeigevorrichtung weist wenigstens einen länglichen dünnen Indikatorstreifen auf. Der Indikatorsteifen ist in unmittelbarer Nachbarschaft der Reparaturstelle lösbar auf der äußeren Schicht der Laminatstruktur aufgebracht. Der Indikatorstreifen ist ausgebildet, eine vordefinierte Restfestigkeit einer Klebung eines Reparaturpatch mit dem umgebenden Verbundmaterial anzuzeigen.
(EN)
The invention relates to a display apparatus for monitoring the structural integrity of a repair location on a laminate structure, produced from a composite material, of a part of the skin of an aircraft. According to the invention, the display apparatus has at least one elongate, thin indicator strip. The indicator strip is detachably applied to the outer layer of the laminate structure in the immediate vicinity of the repair location. The indicator strip is designed to indicate a predefined residual strength of an adhesion of a repair patch to the surrounding composite material.
(FR)
L’invention concerne un dispositif d’indication destiné à surveiller l’intégrité structurelle d’un site de réparation sur une structure stratifiée en matériau composite d’une partie d’une enveloppe extérieure d’aéronef. Le dispositif d’indication comporte au moins une fine bande indicatrice allongée. La bande indicatrice est appliquée de manière amovible sur la couche externe de la structure stratifiée à proximité immédiate du site de réparation. La bande indicatrice est conçue pour indiquer une résistance résiduelle prédéfinie d’une liaison adhésive entre un patch de réparation et le matériau composite environnant.
