<p>A method for producing an aerodynamic part comprising: - producing a preform (300) from a composite material made of a fibrous structure densified by a matrix, said preform having dimensions smaller than those of the aerodynamic part to be produced, - placing the preform made from composite material into a mould (400) having the same internal dimensions and shape as those of the aerodynamic part to be produced, - interposing a ceramic powder (50) between the preform made from composite material and the internal surface (402a) of the mould, said ceramic powder having a thermal expansion coefficient varying, at most, by 4.10"6.K_1 relative to the thermal expansion coefficient of the composite material of the preform, said ceramic powder further having a particle size of between 0.25 µm and 25 µm, - stabilising said powder in such a way as to form, around the preform made from composite material, a ceramic shell having the dimensions and the shape of the aerodynamic part to be produced.</p> |
