Title (EN) NOVEL DIE DESIGN FOR PROPERTY ENHANCEMENT
(FR) NOUVELLE CONCEPTION DE FILIÈRES POUR DES PROPRIÉTÉS AMÉLIORÉES
Abstract:
(EN) Provided are extrusion dies having entrance, orientation, merging (205), and exit (211) sections, which dies may be used to produce fibers having, e.g., oriented reinforcement materials (e.g., PTFE) dispersed within. The dies provide fibers having enhanced mechanical and processing properties. The orientation section comprises orientation channels (203) wherein a ratio of a cross-sectional area having of the channel inlet to a cross-sectional area of the channel outlet is between 2 and 45.
(FR) L'invention concerne des filières d'extrusion présentant des sections d'entrée, d'orientation, de fusion (205) et de sortie (211), lesquelles filières pouvant être utilisées pour produire des fibres contenant, par exemple, des matériaux de renforcement orientés (par exemple, du PTFE) dispersés dans les fibres. Les filières produisent des fibres présentant des propriétés mécaniques et de traitement améliorées. La section d'orientation comprend des canaux d'orientation (203), un rapport d'une surface de section transversale de l'entrée de canal sur une surface de section transversale de la sortie de canal étant compris entre 2 et 45.
