Research Progress of Numerical Simulation of Chemical Vapor Infiltration Used to Prepare Composites

The chemical vapor infiltration is a mature method for preparing continuous fiber reinforced ceramic matrix composites.The research progress of numerical simulation of chemical vapor infiltration is reviewed from three aspects: model of preform structure, simulation of I-CVI, simulation of TG-CVI. The hypothesises, process of mode-ling and degree of agreement with experiments of some important model are reviewed chiefly.
