Beschreibung
Zusammenfassung:	Chemical vapour infiltration apparatus (600) for infiltrating three-dimensional porous preforms (20) mainly extending in a longitudinal direction, the apparatus comprising: a parallelepipedal reaction chamber (610), the side walls (612, 613) of the reaction chamber comprising heating means (615); and a plurality of stacks (50) of loading devices (10) placed in the reaction chamber (610), each loading device (10) being formed from a parallelepipedal recipient equipped with supporting elements intended to receive the porous preforms (20) to be infiltrated. Installation d'infiltration chimique en phase vapeur (600) de préformes poreuses (20) de forme tridimensionnelle s'étendant principalement dans une direction longitudinale, l'installation comprenant : - une chambre de réaction (610) de forme parallélépipédique, les parois latérales (612, 613) de la chambre de réaction comprenant des moyens de chauffage (615), - une pluralité de piles (50) de dispositifs de chargement (10) disposées dans la chambre de réaction (610), chaque dispositif de chargement (10) étant formé d'une enceinte parallélépipédique munie d'éléments de support destinés à recevoir des préformes poreuses (20) à infiltrer.
