Abstract

L’invention concerne un procédé de préparation d’une fibre de carbone, comprenant une étape d’imprégnation d’une fibre à base de cellulose par une solution de chlorure d’ammonium puis une étape de carbonisation de cette fibre, durant laquelle la fibre est soumise à un traitement thermique jusqu’à une température comprise entre 900 et 1500 °C. Durant le traitement thermique, la fibre est soumise à un étirement selon un ratio d’étirement supérieur ou égal à 1,02 jusqu’à une température de valeur comprise entre 180 et 250 °C.The invention relates to a process for preparing a carbon fiber, comprising a step of impregnating a cellulose-based fiber with an ammonium chloride solution and then a step of carbonizing this fiber, during which the fiber is subjected to heat treatment up to a temperature between 900 and 1500 ° C. During heat treatment, the fiber is subjected to stretching at a stretch ratio greater than or equal to 1.02 up to a temperature of between 180 and 250 ° C.
