Abstract

L'invention concerne un procédé de production d'articles renforcés, qui consiste à: a) préparer une composition en poudre d'au moins un matériau thermoplastique et d'environ 2 à 15 % en volume de particules de renforcement. Ces particules de renforcement sont dispersées de manière sensiblement uniforme dans le matériau thermoplastique. Au moins 50 % des particules de renforcement ont une épaisseur inférieure à environ 20 couches, et les couches de particules de renforcement présentent une épaisseur des unités comprise entre environ 0,7 et 1,2 nm; b) chauffer la poudre pour la transformer en une matière fondue; c) imprimer des rotations à la matière fondue dans une cavité du moule pour amener cette dernière à épouser les forme des surfaces de la cavité du moule, la matière fondue ayant une uniformité de dispersion sensiblement identique à celle des particules de renforcement qu'elle renferme, par comparaison avec l'uniformité de dispersion des particules de renforcement renfermées dans la poudre thermoplastique; et d) refroidir la matière fondue pour former un article renforcé.
