Abstract

Ce fil textile comporte une âme inerte formée d'un mono-filament sans torsion axiale en un matériau inorganique susceptible de résister à une atmosphère oxydante à une température > 800° C. Cette âme est entourée de fibres carbonisées et activées présentant, après activation, une surface spécifique rapportée au poids du fil > 1000 m2/g, la proportion de matériau inerte par rapport à la masse totale avant carbonisation et activation étant < 30 %.
