Abstract
Bonded ceramic matrix composite structures such as ceramic panels or beams, and a method for making them, are described, the structures comprising ceramic facing sheets to which are bonded one or an array of relatively thin-walled, hollow, high-stiffness channeled ceramic support elements, the support elements being of modular design with each support being formed by a continuous composite ceramic wall incorporating multidirectional fiber reinforcement and defining a central channel extending, in the bonded structure, in a direction generally parallel with the ceramic facing sheets.
