Abstract
A thermal shielding element which includes a hollow rigid panel in the form of a shell made of a thermostructural composite including fiber reinforcement densified by a matrix, and a thermal insulant filling the panel is obtained by making a rigid block (20) of thermally insulating material of low density, the block having an outside surface whose shape corresponds to the shape of an inside surface of the panel, a fiber preform (11) constituting the reinforcement of the composite material is formed on the block of insulating material, and the fiber preform is densified with the material that constitutes the matrix of the composite material.
