Abstract

La présente invention concerne un matériau composite monolithique autoportant comprenant un aérogel inorganique renforcé par des fibres dispersées, ledit aérogel comprenant un agent épaississant choisi parmi les dérivés de l'acide polyacrylique, les dérivés cellulosiques, l'acétate de calcium, l'acétate de silicium ou leurs mélanges, et ledit matériau possédant une conductivité thermique inférieure à 25 mW/m.K mesurée selon la méthode de la plaque chaude gardée de la norme NF EN 12667 à 20°C et à pression atmosphérique. La présente invention concerne également un procédé de préparation de ces matériaux composites, ainsi que les panneaux multicouches les comprenant et leurs utilisations en tant qu'isolant thermique et/ou phonique, notamment pour le bâtiment, les véhicules ou l'isolation en milieu industriel.
