摘要：The invention relates to a method for the densification of porous substrates bymeans of chemical vapour infiltration. The inventive method consists in: loading theporous substrates to be densified into the loading area of a chamber (10); heating theinternal volume of the aforementioned chamber; and introducing a reactive gas into saidchamber via an inlet which is disposed at one end of same. Before being brought intocontact with the substrates (20) located in the loading area, the reactive gas admittedinto the chamber is pre-heated at least partially by being passed through a conduit (30)which is connected to the gas inlet. Said conduit extends through the loading area and isbrought to the internal temperature of the chamber. The pre-heated reactive gas isdelivered into the loading area by means of one or more openings (33) which aredisposed along the length of the side wall (32) of the conduit.
