Abstract

L’invention propose un panneau isolant à structure multicouche, notamment un panneau à destination d’un aéronef tel qu’un panneau de nacelle ou un bouclier thermique de carénage arrière de mât de moteur, lequel panneau intègre des éléments de liaison facilitant la mise en œuvre ultérieure des fixations du panneau et donc l’intégration du panneau dans l’aéronef. Le panneau comprend une âme isolante (34) entre une première peau (36) et une seconde peau (38), et l’âme comporte des inserts (50) rigides formant des renforts pour la réception de fixations du panneau. Les inserts rigides garantissent une fixation ultérieure pérenne et résistante du panneau, quelle que soit la structure de celui-ci. Avantageusement, l’âme isolante et les inserts sont en céramique, et les inserts sont intégrés dans l’âme au cours de sa fabrication. On obtient un panneau multicouche aux performances thermiques et acoustiques améliorées dont les moyens de fixation sont simples, très résistants et susceptibles de supporter des environnements thermiques très exigeants.
