| titleOfInvention | Carbon-containing composite material part protected against oxidation and its production process |
| abstract | DESCRIPTIVE ABSTRACT Carbon-containing composite material part protected against oxidation and its production process. The process consists of forming a fibrous preform or blank of the part by superimposing layers of carbon-containing fibres (12), the fibres of each layer being parallel to one another and the fibres of the N outermost layers being oriented in the same plane in accor-dance with a first or a second direction, with N > 2, said directions being perpendicular to one another; densifying the preform by a carbon-containing densification material (26); chemically reacting, at a temperature above ambient temperature, the N-1 outermost densi-fied layers of the densified preform with at least one chemical compound in order to form an outer coating of refractory carbonitride or carbide; allowing the assembly to cool in order to form in the outer coating cracks (28) in the direction (z) of its thickness (e) issuing towards the outside, said cracks being oriented in said directions (x,y) and defining between them parallelepipedic carbide or carbonitride blocks (30), followed by the filling of the cracks.
