Stratifié comprenant des feutres de carbone et une feuille de graphite

Laminate of carbon fleece and graphite foil

Schichtkörper aus Kohlenstoffilz und Graphitfolie

Abstract

Die Haftung einer auf einem Schichtstoff aus Kohlenstoff­filz als letzte Schicht aufgebrachten Graphitfolie wird dadurch verbessert, daß in die auf den Filzstapel mit einem carbonisierbaren Klebemittel aufgeklebten Graphit­folie beim Formgeben in einer heizbaren Matrize gitter­artige Eintiefungen gepreßt werden. Bei Temperatur­wechselbeanspruchungen treten keine Ablösungen der Folie vom Filz mehr auf.
The adhesion of a graphite foil applied as last layer to a carbon felt laminate is improved when gridlike depressions are pressed into the graphite foil, adhered to the felt pile with a carbonisable adhesive, in the course of shaping in a heatable mould. Temperature cycling will no longer cause detachment of the foil from the felt. <IMAGE>
