Abstract
A method of manufacturing a ceramic matrix composite component includes casting a tool and placing a ceramic matrix composite layup on the tool. The method further includes sintering the ceramic matrix composite layup at a predetermined sintering temperature at atmospheric pressure while the ceramic matrix composite layup is supported on the tool.
Claims20
A method of manufacturing a ceramic matrix composite component, the method comprising
- casting a tool comprising fused silica materials,
- placing a ceramic matrix composite layup on the tool, and
- performing pressureless sintering to the ceramic matrix composite layup at a predetermined sintering temperature at atmospheric pressure while the ceramic matrix composite layup is supported on the tool so that heat applied to the ceramic matrix composite layup is evenly distributed across the ceramic matrix composite layup during the pressureless sintering.
A method comprising
- treating a mold with a release agent,
- casting a tool comprising fused silica in the mold,
- placing a ceramic matrix composite layup on the tool, and
- sintering the ceramic matrix composite layup at a predetermined sintering temperature while the ceramic matrix composite layup is supported on the fused silica tool so that heat applied to the ceramic matrix composite layup is evenly distributed across the ceramic matrix composite layup.
