Abstract[English]
The present invention relates to a noise damping fibre (10) for a noise damper for compressed air systems, in particular for brake systems of utility vehicles, with surface grooves formed by surface treatment. The present invention further relates to a method (200) for producing a noise damping fibre mesh, wherein the method comprises the steps of: - forming (202) thermoplastic fibres by a molding tool or an extruding tool; - surface treating (204) of the fibres by the molding tool, the extruding tool, or another tool configured to treat the surface of thermoplastic fibres; and - knitting, braiding or weaving (206) a plurality of the surfaced treated fibres (100) to a noise damping fibre mesh.[French]
La présente invention concerne une fibre d'amortissement de bruit (10) destinée à un amortisseur de bruit pour des systèmes d'air comprimé, en particulier pour des systèmes de freinage de véhicules utilitaires, pourvue de rainures de surface formées par traitement de surface. La présente invention concerne en outre un procédé (200) de production d'un maillage de fibres d'amortissement de bruit, le procédé comprenant les étapes consistant à : former (202) des fibres thermoplastiques au moyen d'un outil de moulage ou d'un outil d'extrusion ; traiter la surface (204) des fibres au moyen de l'outil de moulage, de l'outil d'extrusion, ou d'un autre outil conçu pour traiter la surface de fibres thermoplastiques ; et tricoter, tresser ou tisser (206) une pluralité de fibres traitées surfacées (100) en un maillage de fibres d'amortissement de bruit.
