Title (EN) PROCESS FOR PREPARING NOVEL CARBONACEOUS FIBERS
(FR) PROCEDE DE PREPARATION DE NOUVELLES FIBRES CARBONEES
Abstract: front page image
(EN)A process for preparing carbonaceous fibers for use as insulation. The process comprises the steps of subjecting polyacrylonitrile based fibers (12) to ionizing radiation (14) and then heat treating (16) the irradiated fibrous material to make the fibers (12) carbonaceous with an oxygen content less than 2 percent.
(FR)Un procédé qui permet de préparer des fibres carbonées utilisées comme isolant, consiste à soumettre des fibres (12) à base de polyacrylonitrile à un rayonnement ionisant (14), puis à traiter à chaud (16) le matériau fibreux ainsi irradié pour produire des fibres (12) qui sont carbonées et contiennent moins de 2 % d'oxygène.
