Abstract

A process for manufacturing pyrocarbon, includes forming pyrocarbon by a calefaction process from at least one C 2 to C 6 alcohol or polyalcohol precursor, the precursor being ethanol, rough laminar pyrocarbon being obtained by imposing a temperature of between 1250° C. and 1325° C. during calefaction.

Claims (5)

1. A process for manufacturing pyrocarbon, comprising a step of forming pyrocarbon by a calefaction process from at least one C 2 to C 6 alcohol or polyalcohol precursor, the precursor being ethanol, rough laminar pyrocarbon being obtained by imposing a temperature of between 1250° C. and 1325° C. during calefaction.

2. A process for coating a substrate, comprising at least the following step:

forming a pyrocarbon coating on a surface of a substrate by carrying out a process as claimed in claim 1 .

3. A process for densifying a fiber preform, comprising at least the following step:

forming a pyrocarbon matrix in the porosity of the fiber preform by carrying out a process as claimed in claim 1 .
