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.
Process for the production of highly carbonaceous material, wherein the process comprises the combination of a structured precursor comprising a fibre or a set of fibres and a non-structured 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 takes place, and comprising at least one 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 comprises the following steps:
Fibre or set of fibres covered with an organic deposit as intermediate product, wherein the organic deposit comprises at least one cyclic or aromatic organic compound selected from:
Highly carbonaceous material wherein it is bi-structured in order to comprise a structured part, comprising a carbonized fibre or a set of carbonized fibres, and an unstructured part comprising a carbonized cyclic organic or aromatic compound and in that it has an overall porosity greater than 5%, preferably greater than 10%.
