A method of manufacturing a part out of impervious thermostructural composite material, the method comprising forming a porous substrate from at least one fiber reinforcement made of refractory fibers, and densifying the reinforcement by a first phase of carbon and by a second phase of silicon carbide. The method then continues by impregnating the porous substrate with a composition based on molten silicon so as to fill in the pores of the substrate.

Method of manufacturing a part out of impervious thermostructural composite material

To provide a thermal connection that can withstand mechanical stress in a high temperature structure comprising a panel having one face carrying a circuit made up of tubes in which a fluid flows, the outside walls of the tubes are covered in respective high thermal conductivity textile layers. The structure further comprises holding means for holding the tubes pressed in non-rigid manner against the panel. The structure enables heat exchange to take place between the panel and the fluid in order to cool the panel, to heat the fluid, or indeed in order to do both.
