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.
Claims6
A cooled refractory structure having a front face intended to be exposed to very high temperatures, wherein said structure is formed of a composite material having a fibrous preform including a fibrous reinforcement texture and a matrix, the composition of the matrix varying substantially without discontinuity along a thickness direction of the structure, from being an essentially refractory material, in the region of a front face intended to be exposed to very high temperatures, to being an essentially heat conductive material said fibrous preform comprising fibers having a nonuniform density distribution.
