Abstract
A method of forming a ceramic matrix composite component. The ceramic matrix composite component is adapted for use in a gas turbine engine. The method including forming the component using ceramic materials and infiltrating the component with a matrix material.
Claims8
A method of forming a ceramic matrix composite component,
- the method comprising providing a first set of ceramic tows that each have a first filament composition,
- providing a second set of ceramic tows that each have a second filament composition that is different from the first filament composition by varying at least one of a mean filament size of filaments included each tow, a filament size distribution of each tow, and a number of filaments per each tow,
- forming a first section of the component using tows from the first set of ceramic tows,
- forming a second section of the component that is different from the first section using tows from the second set of ceramic tows,
- infiltrating the component with matrix material to produce a first intra-tow porosity in the first section of the component and a second intra-tow porosity in the second section of the component that is different from the first intra-tow porosity of the first section.
