Title (EN) PROCESS FOR GAS PHASE SURFACE TREATMENT
(FR) PROCÉDÉ DE TRAITEMENT DE SURFACE EN PHASE GAZEUSE
Abstract:
(EN) A gas phase surface treatment for treating carbon fiber including (a) exposing a carbon fiber to a gaseous oxidizing atmosphere to form a modified carbon fiber with an oxidized fiber surface; followed by (b) exposing the oxidized fiber surface to a gaseous nitrogen-containing atmosphere to form a modified carbon fiber with a nitrogen-enriched surface, wherein the nitrogen-enriched surface exhibits an increase in surface nitrogen to surface carbon (N/C) ratio as compared to the surface of the carbon fiber prior to exposure at (a). Steps (a) and (b) are carried out continuously without any additional intervening surface treatment.
(FR) L'invention concerne un procédé de traitement de surface en phase gazeuse destiné à traiter une fibre de carbone. Le procédé consiste: a) à exposer une fibre de carbone à une atmosphère oxydante gazeuse pour former une fibre de carbone modifiée présentant une surface de la fibre oxydée; puis b) à exposer la surface de la fibre oxydée à une atmosphère azotée gazeuse pour former une fibre de carbone modifiée présentant une surface enrichie en azote. La surface enrichie en azote présente une augmentation du rapport surface azote à surface carbone (N/C) par comparaison avec la surface de la fibre de carbone avant exposition de l'étape a). Les étapes a) et b) sont réalisées en continu sans aucun traitement de surface intermédiaire supplémentaire.
