ABSTRACT:
The invention relates to apparatus for use in chemical vapor infiltration and deposition (CVI/CVD) processes. More specifically, the invention relates to a preheater for heating a reactant gas inside a CVI/CVD furnace, and a fixture for depositing a matrix within a stack of porous structures by a pressure gradient CVI/CVD process. The invention is particularly suited for the simultaneous CVI/CVD processing of large quantities (hundreds) of aircraft brake disks.
