Title
(EN) METHOD FOR MANUFACTURING FIBRE PREFORM
(FR) PROCÉDÉ DE FABRICATION D'UNE PRÉFORME DE FIBRE
Abstract
(EN)
The invention relates to a method for manufacturing a fibre preform and/or for modifying properties of the same by an ALD method. According to the invention, one or more fibre preforms are placed in an atomic layer deposition reactor and a first catalyst is supplied into a core of the fibre preform in order to produce a catalysing layer onto a surface of the core of the fibre preform. Next, one or more dopants are supplied into the core of the fibre preform, whereby the first catalyst causes two or more deposition layers to be formed onto the surface of the core of the fibre preform.

L'invention concerne un procédé pour fabriquer une préforme de fibre et/ou modifier des propriétés de celle-ci par un procédé de dépôt de couches atomiques. Selon l'invention, une ou plusieurs préformes de fibres sont placées dans un réacteur de dépôt de couches atomiques et un premier catalyseur est acheminé dans le coeur de la préforme pour produire une couche catalysante sur une surface du coeur de la préforme. Un ou plusieurs dopants sont ensuite acheminés dans le coeur de la préforme, une ou plusieurs couches de dépôt se formant sur la surface du coeur de la préforme sous l'effet du premier catalyseur.
