Abstract

A brake component is disclosed. In various embodiments, the brake component includes a ceramic matrix composite (CMC) structure including a plurality of nominally dense plies, interleaved with a plurality of interlayers, wherein the plurality of nominally dense plies and the plurality of interlayers are bonded by at least one of a Field Assisted Sintering Technique (FAST), a Spark Plasma Sintering (SPS) process, or a localized heating process. In various embodiments, the brake component is a rotor disk or a stator disk.

First claim

What is claimed is:

1. A brake component, comprising:
a ceramic matrix composite (CMC) structure including a plurality of nominally dense plies, interleaved with a plurality of interlayers, wherein the CMC structure comprises greater than sixty percent by volume of fiber,
wherein the plurality of nominally dense plies and the plurality of interlayers are bonded by at least one of a Field Assisted Sintering Technique (FAST), a Spark Plasma Sintering (SPS) process, a radiative heating process, or a localized Joule heating process, and
wherein the plurality of nominally dense plies are densified using an atomic deposition (ALD) process prior to bonding.

2. The brake component of claim 1 , wherein the brake component is a rotor disk or a stator disk.

3. The brake component of claim 1 , wherein the CMC structure comprises at least one of a silicon-carbide fiber/silicon-carbide matrix, a carbon fiber/carbon matrix or a carbon fiber/silicon-carbide matrix.

4. The brake component of claim 1 , wherein the CMC structure comprises at least one of an alumina matrix, a mullite matrix or a zirconium diboride matrix.

5. The brake component of claim 1 , wherein the CMC structure comprises one or more compositions, including:
borides, carbides, oxides, phosphides, nitrides or mixed phases, including oxynitrides, or oxycarbides;
carbon or silicon-based compositions;
refractory metal carbides; or
silica and phosphate-based glasses or glass ceramics.

6. The brake component of claim 1 , wherein the plurality of interlayers comprises forcespun or electrospun nanofiber mats or nanowire metal meshes, nonwoven fabrics made of preceramic polymer nanofibers or polyacrylonitrile nanofibers.

7. The brake component of claim 1 , wherein the plurality of interlayers comprises at least one of a particulate, a chopped fiber, a nanotube, a resin or a slurry.

8. The brake component of claim 1 , wherein the CMC structure is characterized by a gradation of a CMC composition among the plurality of nominally dense plies.

9. The brake component of claim 8 , wherein the gradation of the CMC composition is defined between a braking surface and a core layer of a rotor disk or a stator disk.

10. The brake component of claim 1 , wherein at least one of the plurality of nominally dense plies comprises a monolithic ceramic composition.

11. An article of manufacture, comprising:
a ceramic matrix composite (CMC) structure including a plurality of nominally dense plies, interleaved with a plurality of interlayers, wherein the CMC structure comprises greater than sixty percent by volume fiber,
wherein the plurality of nominally dense plies and the plurality of interlayers are bonded by at least one of a Field Assisted Sintering Technique (FAST), a Spark Plasma Sintering (SPS) process, a radiative heating process, or a localized Joule heating process, and
wherein the plurality of nominally dense plies are densified using an atomic deposition (ALD) process prior to bonding.

12. The article of manufacture of claim 11 , wherein the CMC structure comprises at least one of a silicon-carbide fiber/silicon-carbide matrix, a carbon fiber/carbon matrix, a carbon fiber/silicon-carbide matrix, an alumina matrix, a mullite matrix, or a zirconium diboride matrix.

13. The article of manufacture of claim 11 , wherein the CMC structure comprises one or more compositions, including:
borides, carbides, oxides, phosphides, nitrides or mixed phases, including oxynitrides, or oxycarbides;
carbon or silicon-based compositions;
refractory metal carbides; or
silica and phosphate-based glasses or glass ceramics.

14. The article of manufacture of claim 11 , wherein the plurality of interlayers comprises forcespun or electrospun nanofiber mats or nanowire metal meshes, nonwoven fabrics made of preceramic polymer nanofibers or polyacrylonitrile nanofibers.

15. The article of manufacture of claim 11 , wherein the plurality of interlayers comprises at least one of a particulate, a chopped fiber, a nanotube, a resin or a slurry.

16. The article of manufacture of claim 11 , wherein the CMC structure is characterized by a gradation of a CMC composition among the plurality of nominally dense plies.

17. The article of manufacture of claim 11 , wherein at least one of the plurality of nominally dense plies comprises a monolithic ceramic composition.

18. A method of manufacturing a layered component, comprising:
densifying, using an atomic layer deposition (ALD) process, a feedstock to generate a plurality of nominally dense plies, wherein the plurality of nominally dense plies include ceramic matric composite (CMC) structures;
assembling the plurality of nominally dense plies, interleaved with a plurality of interlayers, to generate a preform structure; and
bonding the preform structure via at least one of a Field Assisted Sintering Technique (FAST), a Spark Plasma Sintering (SPS) process, a radiative heating process, or a localized Joule heating process.
