Abstract

L'invention concerne un procédé de moulage de grandes pièces, qui consiste à disposer d'une matière plastique renforcée fondue (41) comprenant au moins un matériau thermoplastique et des particules de renforcement dispersées à l'intérieur d'au moins un matériau thermoplastique. Les particules de renforcement comprennent moins de 15 % d'un volume total de la matière plastique fondue, au moins 50 % des particules de renforcement ayant une épaisseur inférieure à environ 20 nanomètres, et au moins 99 % des particules de renforcement ayant une épaisseur inférieure à environ 30 nanomètres. Le procédé consiste ensuite à transférer une formation tubulaire de la matière plastique fondue dans un moule (29) ayant une cavité (44) du moule délimitée par des surfaces (43) du moule, lesquelles (43) correspondent à une configuration de la pièce à mouler; puis à appliquer un gaz sous pression sur une partie interne de la formation tubulaire pour expanser cette dernière et l'amener à épouser les formes des surfaces (43) du moule. Le procédé consiste enfin à solidifier la matière plastique fondue pour former la pièce; puis à extraire ladite pièce du moule.
