Simulation Study on the Influence of H₂ on the Carbon Deposition in ICVI of Thick-Walled Perform

Abstract:

A two dimensional model was employed to simulate the densification process of thick-walled hollow cylinder preform of C/C composite. Using the hydrogen inhibition model, carbon deposition processes under different partial pressures were compared and the efficiency of densification was analyzed. Then the density distribution of some definite time was analyzed to explain the mechanism of hydrogen inhibition. The results showed that with the adjunction of hydrogen, density distribution in preform was improved while the deposition process took a longer time.
