CERAMIC MATRIX COMPOSITES AND METHODS FOR PRODUCING CERAMIC MATRIX COMPOSITES

摘要

A ceramic matrix composite includes a plurality of fibers embedded in a matrix. The composition of the matrix is selected to achieve a desired relationship between the mechanical and thermal properties of the matrix and the fibers.

主权项

1. A method of producing a ceramic matrix composite, comprising the steps of:
forming a network of fibers; and depositing a matrix material comprising silicon and carbon onto the fibers to form silicon carbide; wherein the depositing the matrix material comprises at least one of the group consisting of (1) depositing substantial amounts of silicon or carbon in excess of silicon carbide stoichiometric amounts, (2) introducing an oxygen containing gas, (3) introducing a halogen gaseous species, (4) introducing an organometallic gaseous species, or (5) a combination thereof.
