The multi-scale porosity model
depicting infiltration induced changes of carbon fiber preform and the
mathematical model depicting ICVI process for fabrication of C/SiC composites
were developed. The integrated model was proposed to simulate densification
behavior of C/SiC composites. The correspondences of calculation results and
the experimental data indicate that the model is reasonable and feasible to
characterize ICVI process of C/SiC composites. The calculated results, such
as distribution of local porosity, uniformity of densification and evolution
of global porosity during infiltration process, lay foundation of further
research and optimization of ICVI process for fabrication of C/SiC composites.
