Abstract

L'invention concerne un procédé de fabrication de fibres précurseur de fibres de carbone comprenant une lignine et un alcool polyvinylique (PVA) et contenant au moins 60 % en masse de lignine par rapport à la masse totale lignine-PVA., ledit procédé comprenant la réalisation d'une solution de lignine et de PVA dans un solvant, l'injection de la solution contenant la lignine et le PVA dans un bain de coagulation pour obtenir une ou plusieurs fibres, contenant au moins 60 % en masse de lignine, coagulées par filage en voie humide. L'invention concerne aussi un matériau comprenant ou consistant en une ou plusieurs fibres précurseur de fibres de carbone.)
