THE ROLE OF GAS-PHASE REACTIONS IN MODELING OF THE FORCED-FLOW CHEMICAL-VAPOR INFILTRATION PROCESS uri icon

abstract

  • An analytical model is presented, which includes the effects of both gasphase and surface reactions, and the pressure changes due to the chemical reactions in the forcedflow chemical vapor infiltration (FCVI) process. For the FCVI process controlled by the gasphase reactions, improvements of the process by using the forcedflow are limited. However, for the FCVI process controlled by the surface reactions, the process can be improved with the use of the forcedflow technique. For the surfacereactioncontrolled FCVI process, the degree of improvement increases with increasing permeability of the composite preform. In other words, advantages due to the forcedflow are higher at the initial stage of the process when the porosity of the composite preform is high. 1993, The Electrochemical Society, Inc.
