Abstract
A two-dimensional axisymmetric model for the densification behavior of C/SiC composites in isothermal chemical vapor infiltration was developed according to the structural feature of C/SiC composites and the physico-chemical phenomena of the isothermal chemical vapor infiltration process. A mathematical model was proposed to characterize the densification behavior of a small scale thruster liner component of C/SiC composites for a rocket engine by the finite element method. The density was measured and X-ray CT was inspected in order to validate the model. The analogical regularities represented by the calculation results and the experimental data show that the model developed in this article is reasonable and feasible to characterize the densification behavior of C/SiC composites in ICVI process. The calculated results, such as distribution and evolution of porosity and density of thruster liner component, lay the foundation of further research and optimization of ICVI process for fabrication of C/SiC composites components.
