Abstract

L'invention a pour objet un matériau à structure de type sandwich (1) à thermocomprimer, comprenant une âme (2) disposée entre une première peau (3) et une seconde peau (4), ladite première peau (3) comprenant une première matrice de polymère (3a), ladite seconde peau (4) comprenant une seconde matrice de polymère (4a), caractérisé par le fait que ladite âme (2) comprend une troisième matrice de polymère (2a) dans laquelle est réparti un agent de porosité (5) configuré pour créer une porosité dans l'âme (2), de telle sorte que, lorsque ledit matériau (1) est thermocomprimé, les première (3a) et seconde (4a) matrices de polymère adhèrent à la troisième matrice de polymère (2a), et l'agent de porosité (5) est en outre configuré pour conserver ou augmenter ladite porosité dans l'âme (2) lorsque ledit matériau (1) est thermocomprimé.
