Analysis of the Isothermal Forced Flow Chemical Vapour Infiltration Process. Part I: Theoretical Aspects

In this paper the densification of a cylindrical pore due to a first order heterogeneous deposition reaction on the wall is described. The basic understanding of these mechanisms can aid in the prediction of the infiltration time and composite porosity after derkjication. The results of the modeling are com-pared with experimental results which are reported in an additional paper, i.e. Part 2 of this study. The main characteristic parameter that determines the in$ltration behaviour is the gas velocity.
