The present invention relates to a method of forming an article on a tool, the tool having one longitudinal direction and one transversal direction, wherein the method comprises the steps of: - arranging a stack (22) of plies (23) comprising fibres, so that when positioned on the tool (21) the ply (24) arranged closest to the tool (21) and the ply (25) arranged furthest away from the tool (21) have the fibres substantially orthogonal (3) to the longitudinal direction (L) of the tool,and arranging at least one ply having the fibres substantially in the same direction (2) as the longitudinal direction (L) of the tool(21) between the plies having fibres substantially orthogonal (3) to the longitudinal direction of the tool (21), -conforming the stack to the tool with a forming medium; and -removing the article from the tool. The present invention also relates to an article produced according to the method.
La présente invention concerne un procédé pour former un article sur un outil, l'outil ayant un sens longitudinal et un sens transversal. Le procédé comprend les étapes suivantes : - agencer une pile (22) de couches (23) comprenant des fibres, de sorte que dans sa position sur l'outil (21), la couche (24) agencée le plus près de l'outil (21) et la couche (25) agencée le plus loin de l'outil (21) aient leurs fibres substantiellement orthogonales (3) au sens longitudinal (L) de l'outil, - agencer au moins une couche dont les fibres sont substantiellement dans le même sens (2) que le sens longitudinal (L) de l'outil (21) entre les couches dont les fibres sont substantiellement orthogonales (3) au sens longitudinal de l'outil (21), - faire correspondre la forme de la pile à la forme de l'outil avec un moyen de formage ; et - enlever l'article de l'outil. La présente invention concerne aussi un article produit conformément à ce procédé.
