Abstract

Un noyau de gypse à ensemble de cellules ouvertes comprend une matrice d'interverrouillage de gypse ayant des vides d'air distribués à l'intérieur de celle-ci. Les vides d'air définissent des cellules ayant des parois de cellules formées par la matrice d'interverrouillage. La matrice d'nterverrouillage comprend en outre des canaux répartis à l'intérieur de celle-ci. Les canaux interconnectent les vides d'air et comprennent des ouvertures dans les parois de cellules.
