(EN) METHOD AND INSTALLATION FOR PRODUCING A MULTI-LAYERED WET FRICTION MATERIAL
(FR) PROCÉDÉ ET INSTALLATION DE FABRICATION D’UN MATÉRIAU DE FRICTION HUMIDE MULTICOUCHE
Abstract
(DE)
Die Erfindung betrifft ein Verfahren zum Herstellen eines mehrlagigen Nasslauf-Reibmaterials (14) mit mindestens einer Unterlage (2) und mindestens einer Oberlage (1), die stoffschlüssig miteinander verbunden werden. Um das Herstellen eines mehrlagigen Nasslauf-Reibmaterials (14) zu vereinfachen, werden die Unterlage (2) und die Oberlage (1) zunächst aus unterschiedlichen Materialien unabhängig voneinander hergestellt, bevor die Unterlage (2) mit der Oberlage (1) verbunden wird.
(EN)
The invention relates to a method for producing a multi-layered wet friction material (14) having at least one bottom layer (2) and at least one top layer (1), which are bonded to one another. To simplify the production of a multi-layered wet friction material (14), the bottom layer (2) and the top layer (1) are initially produced independently of one another from different materials, before the bottom layer (2) is connected to the top layer (1).
(FR)
L’invention concerne un procédé de fabrication d’un matériau de friction humide (14) multicouche comprenant au moins une couche inférieure (2) et au moins une couche supérieure (1) qui sont assemblées par liaison de matière. Afin de simplifier la fabrication d’un matériau de friction humide (14) multicouche, la couche inférieure (2) et la couche supérieure (1) sont réalisées dans des matériaux différents mutuellement indépendants avant même que la couche inférieure (2) ne soit assemblée à la couche supérieure (1).
