Method for densification by chemical vapor infiltration
The invention relates to a method for densifying a plurality of fibrous preforms arranged in a chamber (12) of a densifying furnace (11) by chemical vapor infiltration, the method comprises at least the following steps a) and b), each repeating more than one time: a) introducing a first gas phase, the thermal decomposition of which makes it possible to form a matrix in the pores of a plurality of fibrous preforms; b) introducing a second gas phase, simultaneously decompressing the furnace chamber, such that the introduction of the second gas phase is performed simultaneously with the discharge of the first gas phase from the chamber, the temperature of the second gas phase being less than or equal to 25 DEG C when the second gas phase is introduced into the chamber of the furnace.
本发明涉及通过化学气相渗透，用于在致密化炉（11）的室（12）中所布置的多个纤维预成型件的致密化的方法，该方法至少包括以下步骤a）和b），每个步骤重复一次以上：a）引入第一气相，所述第一气相的热分解使得可以在多个纤维预成型件的孔中形成基质；b）引入第二气相，同时地减压炉室，使得第二气相的引入与将第一气相从室排出同时进行，在将第二气相引入炉的室中时，第二气相的温度小于或等于25°C。
