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.
