Oxidation Resistance of 2D C/SiC Composites Fabricated by FCVI

Abstract:

Two-dimensional waved carbon fiber preforms were chemical vapor infiltrated under forced flow, thermal gradient mode for preparation of 2D C/SiC composites. In order to improve the oxidation resistance of the C/SiC composites, B4C powders were added into the preforms and aqueous silica sol-B4C compound coating was claded on the surfaces of composites. It was found that the oxidation resistance of 2D C/SiC composites at temperatures lower than 1273K was improved because of the formation of B2O3 and borosilicate glass by preventing the diffusion of oxygen.
