ABSTRACT:
The structure consists of a composite material having a reinforcement texture and a matrix. The composition of the matrix varies practically without discontinuity, in the structure's thickness direction, from an essentially refractory material (13) in the region of the front face intended to be exposed to very high temperatures, up to a material that is essentially heat conductive (16). Cooling fluid circulation conduits (15) can be arranged within the structure at a portion where the matrix is essentially heat conductive.
