Abstract
Method for manufacturing a part made from carbon/carbon composite material, comprising: the formation of a carbonaceous preform, partial densification of the preform by a pyrocarbon matrix thus forming a partially densified blank, the impregnation of the partially densified blank with an impregnation solution including ceramic particles or ceramic precursors, and the drying of the impregnated blank. Furthermore, the viscosity of the dispersion or impregnation solution is controlled in order to control the homogeneity of the distribution of the ceramic particles in the part of the impregnated composite material during drying.

A method for manufacturing a part made from carbon/carbon composite material, comprising:
- formation of a fibrous carbonaceous preform;
- partial densification of the preform by a pyrocarbon matrix in order to obtain a partially densified blank;
- impregnation of the partially densified blank with an impregnation solution including ceramic particles or ceramic precursors;
- and,
- drying of the impregnated blank,
- wherein a viscosity of the impregnation solution is controlled in order to control a homogeneity of a distribution of the ceramic particles in at least a part of the impregnated blank during drying, the viscosity of the impregnation solution being controlled so as to maintain a dynamic viscosity value of between 12 and 700 mPa s.
