    Abstract: 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. A method for producing a ceramic matrix composite, comprising the steps of: forming a network of fibers; and depositing a matrix material having a first component and a second component on the network of fibers, wherein one of the first and second components is deposited in an amount greater than its stoichiometric amount in relation to the other component. A ceramic matrix composite, comprising: a matrix having a creep rate at a specified temperature, the matrix including a first component and a second component, wherein one of the first and second components is present in an amount greater than its stoichiometric amount in relation to the other component; and a plurality of fibers embedded in the matrix, the fibers having a lower or the same creep rate at the specified temperature than the creep rate of the matrix. Preferably the matrix material is SiC, which means that either there is more Si or there is more C. The ceramic fibers contain preferably an interface coating of silicon doped BN. The matrix material is preferably made by CVI.

    Abstract: A fiber having an environmental barrier coating is provided that includes, in one illustrative form, a Hi Nicalon preform assembled in a tooling for chemical vapor infiltration and cleaned to remove sizing char from fibers of the Hi Nicalon preform; a ytterbium doped silicon carbide coat located over the Hi Nicalon preform; a boron nitride interface coat applied over the ytterbium doped silicon carbide coat; and a silicon carbide coat applied over the boron nitride interface coat. In another embodiment the fiber has an environmental barrier coating, comprising: a Hi Nicalon S fiber; wherein the Hi Nicalon S fiber is coated in tow form with yttrium doped silicon carbide; and a silicon doped boron nitride coat applied over the yttrium doped silicon carbide. In a third embodiment the fiber has an environmental barrier coating, comprising: a T-300 carbon fiber preform assembled in tooling for chemical vapor infiltration; alternating layers of silicon carbide and boron carbide are applied over the preform; and a silicon doped boron nitride interface coat applied over the silicon carbide coat.
