Abstract
A transpirational cooling panel comprises a porous ceramic matrix composite layer and a porous high-temperature fabric layer. A machined ceramic fiber batting is located between the porous ceramic matrix composite layer and the porous high-temperature fabric layer. A ceramic stitching joins the porous ceramic matrix composite layer and the porous high-temperature fabric layer through the machined ceramic fiber batting.
Claims20
A polymer-containing intermediate for a transpirational cooling panel, comprising:
- a ceramic fabric layer;
- a porous high-temperature fabric layer;
- a ceramic fiber batting comprising a machined outer surface, the ceramic fiber batting located between the ceramic fabric layer and the porous high-temperature fabric layer;
- a homogeneous cellulosic matrix that binds fibers of the ceramic fiber batting to provide rigidity to the ceramic fiber batting;
- and
- a ceramic stitching joining the ceramic fabric layer and the porous high-temperature fabric layer through the ceramic fiber batting.
A polymer-containing intermediate for a transpirational cooling panel, comprising:
- a ceramic fabric layer;
- a porous high-temperature fabric layer;
- one or more layers of a ceramic fiber batting comprising a machined outer surface, the ceramic fiber batting located between the ceramic fabric layer and the porous high-temperature fabric layer;
- and
- a homogeneous cellulosic matrix that binds fibers of the ceramic fiber batting to provide rigidity to the ceramic fiber batting.
A stitched polymer-containing intermediate for a transpirational cooling panel, comprising:
- a porous ceramic matrix layer;
- a porous high-temperature fabric layer;
- one or more layers of a ceramic fiber batting comprising a machined outer surface;
- a homogeneous cellulosic matrix that binds fibers of the ceramic fiber batting to provide rigidity to the ceramic fiber batting;
- and
- a ceramic oxide stitching joining the porous ceramic matrix layer and the porous high-temperature fabric layer through the ceramic fiber batting.
A method of forming a transpirational cooling panel, comprising:
- providing a polymer-containing intermediate for the transpirational cooling panel, the polymer-containing intermediate comprising
- a porous ceramic fabric layer,
- a porous high-temperature fabric layer,
- one or more layers of a ceramic fiber batting comprising a machined outer surface,
- a homogeneous cellulosic matrix that binds fibers of the ceramic fiber batting to provide rigidity to the ceramic fiber batting, and
- a ceramic stitching joining the porous ceramic fabric layer and the porous high-temperature fabric layer through the ceramic fiber batting;
- and
- removing the homogeneous cellulosic matrix from the ceramic fiber batting to restore flexibility to the ceramic fiber batting.
