Abstract
A process for the production of highly carbonaceous material, including combining a structured precursor including fibres and an unstructured precursor, in the form of a fluid, wherein the fluid has a viscosity of less than 45,000 mPa·s−1 at the temperature at which the combination step occurs, and including at least a cyclic organic or aromatic compound in the molten state, or in solution at a concentration by weight of less than or equal to 65%, in order to obtain a combined precursor corresponding to the structured precursor covered by the unstructured precursor, wherein the process further includes step of thermal and dimensional stabilization of the combined precursor in order to obtain fibres covered with a cyclic organic or aromatic compound deposit, and a step of carbonization of the fibres covered with a cyclic organic or aromatic compound deposit in order to obtain a highly carbonaceous material.
