Abstract

L'invention concerne une plaque composée d'une pluralité de particules et/ou de fibres de charge liées par un liant, les particules et/ou fibres de charge étant mélangées au liant et le liant durcissant par la suite. L'invention concerne également un procédé de fabrication d'une telle plaque. Pour obtenir une dureté et une rigidité comparables à celles d'une plaque traditionnelle, mais un poids réduit, le liant doit occuper un volume supérieur et présenter une structure essentiellement incompressible à l'état durci. Selon ledit procédé, l'ensemble des particules et/ou fibres de charge est mélangé au liant ou chargé de liant, et le liant durcit; les particules et/ou fibres de charge mélangées au liant ou chargées de liant sont façonnées sous forme de plaque plate par traitement mécanique correspondant et/ou les particules et/ou fibres de charge sont préformées approximativement sous forme de plaque avant mélange au liant ou charge avec le liant; et le liant occupe un volume supérieur et durcit simultanément ou ultérieurement, puis présente une structure essentiellement incompressible.
