US 12,584,214 B2 · Embedded wire chemical vapor deposition (EWCVD)

Abstract

Methods of forming a ceramic matrix, as well as fiber preforms and methods of forming fiber preforms to facilitate formation of a ceramic matrix are provided. The method includes obtaining a fiber preform to facilitate forming the ceramic matrix. The fiber preform includes a fiber layer with a plurality of fibers and a heating element embedded within the fiber preform. The method also includes heating the fiber preform via the heating element embedded within the fiber preform, and depositing matrix material into the fiber preform by embedded wire chemical vapor deposition (EWCVD) of the matrix material during the heating of the fiber preform by the heating element. The chemical vapor deposition of the matrix material within the fiber preform facilitates formation of the ceramic matrix.
