Abstract
The piece made of composite material comprises a plate and a plurality of stiffeners integrally formed with the plate. A metal wall is fixed to the edges of the stiffeners and is provided with passages for circulating the fluid. The plate exposed to the heat flux radiates towards the metal wall through the gaps between the stiffeners, and it also performs the structural function. The invention can be used with structures that are exposed to very high heat flux: the walls of jet combustion chambers, the walls of space plane vehicles, the walls of nuclear fusion reactors.
