Abstract
Thermostructural composite structure having a compositional gradient, formed from a porous core () made of a refractory having a pore volume content of greater than or equal to 80%. The core () lies between two intermediate layers () comprising the carbon fiber reinforcement, densified by a matrix composed of the carbon phase and of a ceramic phase, and a refractory solid filler. Two monolithic ceramic shells () cover the intermediate layers in order to give stiffness to the entire structure.
