CERAMIC MATRIX COMPOSITE MANUFACTURING
A method of manufacturing a ceramic matrix composite component may include introducing a gaseous precursor into an inlet portion (312) of a chamber that houses a porous preform and introducing a gaseous mitigation agent into an outlet portion (313) of the chamber (312) that is downstream of the inlet portion of the chamber (310). The gaseous precursor may include methyltrichlorosilane (MTS) and the gaseous mitigation agent may include hydrogen gas. The introduction of the gaseous precursor may result in densification of the porous preform(s) and the introduction of the gaseous mitigation agent may shift the reaction equilibrium to disfavor the formation of harmful and/or pyrophoric byproduct deposits, which can accumulate in an exhaust conduit (340) of the system.
