Microstructure of 3d Textile C/pyc/sic Composites Prepared by Chemical Vapor Infiltration
Ceramic matrix composites (CMCs) is one of the most promising candidates for high temperature structural material, in which SiC matrix exhibits an excellent oxidation resistance because of the formation of a protective layer of silica which limits further oxidation [1]. CMCs with continuous fibers exhibit attractive properties such as low densities, high elastic moduli, and high strengths at el...
متن کاملGrinding Effect of C/C-SiC Composites Prepared by Isothermal Chemical Vapour Infiltration during Braking Process
A kind of 2.5-dimensional C/C-SiC composites was fabricated by using Isothermal Chemical Vapour Infiltration process (ICVI). Frictional properties of this material were evaluated by using MM-1000 under dry condition. Average dynamic friction coefficient of it was 0.16, static friction coefficient and average coefficient stability were 0.15 and 0.56, respectively. However, weight wear rate was l...
متن کاملModelling of Pyrocarbon Chemical Vapor Infiltration
The chemical vapor infiltration (CVI) of pyrocarbon is used to produce carbon matrix of C/C composites. This process involves complex physico-chemical phenomena such as the transport of gas mixtures (hydrocarbons and hydrogen) in the reactor and inside the fibrous preform, chemical reactions (pyrolysis and deposition), and the structural evolution of the preform. A global modelling approach has...

متن کاملModeling and simulation of materials synthesis: Chemical vapor deposition and infiltration of pyrolytic carbon
Chemical vapor deposition and infiltration of pyrolytic carbon for the production of carbon fiber reinforced carbon is studied by modeling approaches and computational tools developed recently. Firstly, the development of a gas-phase reaction mechanism of chemical vapor deposition (CVD) of carbon from unsaturated light hydrocarbons (C2H4, C2H2, and C3H6) is presented. The mechanism consisting o...
