Abstract

La présente invention concerne un procédé de production d'éléments de construction légers à partir d'un matériau composite fibreux, ainsi que des profilés de construction légers pouvant être produits selon ce procédé. Selon ledit procédé, des fibres de bois sont extrudées en étant mélangées avec une matière thermoplastique pour former un tel élément de construction léger. Le procédé se caractérise en ce que l'on utilise des fibres de bois produits au moyen d'un procédé faisant appel à un raffineur thermomécanique, lesquels présentent une longueur de fibre moyenne de 2-20 mm et un rapport L/D ≥ 5, et qu'on les traite d'abord pour former un agglomérat de fibres pouvant être dosé qui est ensuite extrudé pour former l'élément de construction léger. Ledit procédé permet de produire des éléments de construction légers présentant une grande résistance mécanique.
