Definitions
- the present invention relates generally to turbines. More specifically, to a ceramic matrix composite (CMC) component and a method of attaching a metal seal to the ceramic matrix composite component.
- CMC ceramic matrix composite
- CMC ceramic matrix composites
- One method of manufacturing CMC components relates to the production of silicon carbide matrix composites containing fibrous material that is infiltrated with molten silicon, herein referred to as the Silcomp process.
- the fibers generally have diameters of about 140 micrometers or greater, which prevents intricate, complex shapes, such as turbine blade components, to be manufactured by the Silcomp process.
- CMC turbine blades are the method known as the slurry cast melt infiltration (MI) process.
- MI slurry cast melt infiltration
- CMCs are produced by initially providing plies of balanced two-dimensional (2D) woven cloth comprising silicon carbide (SiC)-containing fibers, having two weave directions at substantially 90° angles to each other, with substantially the same number of fibers running in both directions of the weave.
- CMC ceramic matrix composite
- a ceramic matrix composite component includes a first end and a second end.
- the ceramic matrix composite component includes a CMC metal interface member attached to the second end.
- the CMC metal interface member is operable to join to a static seal in a gas turbine.
- a method of attaching a static seal to a ceramic matrix composite component includes providing a ceramic matrix composite component having a first end and a second end.
- the method includes providing a CMC metal interface member.
- the method includes attaching the CMC metal interface member to the second end of the ceramic matrix composite component.
- the method includes providing a static seal and joining the static seal to the CMC metal interface member.
- the CMC metal interface member forms a plenum for purging rotor air.
- FIG. 1 is a perspective schematic section view of a CMC component of the present disclosure.
- FIG. 2 is a perspective schematic section view of a CMC component of the present disclosure.
- FIG. 3 is a schematic top partial view of a CMC component of the present disclosure.
- FIG. 4 is a flow chart of the method of attaching a static seal to a CMC component of the present disclosure.
- CMC ceramic matrix composite
- One aspect of an embodiment of the present disclosure includes providing a honeycomb seal attachment for a CMC component. Another aspect of the present disclosure is that the system allows for different thermal growth of the CMC component and the CMC metal interface member.
