摘要 |
The invention relates to a film-boiling densification method for a porous structure (mixed gas-liquid method) ( 5 ) consisting in immersing of the porous structure into a liquid precursor, a hydrocarbon, for example, and heating the system in order to deposit the decomposition product of said liquid precursor, for example carbon, into the pores of the porous structure, characterized in that the flow of the liquid precursor entering the porous structure is reduced, for example by means of a filter ( 52 ) made of polytetrafluorethylene surrounding the structure so as to reduce the vaporization phenomenon of the liquid precursor around the porous structure to be densified. |
