Abstract:
An impregnation mandrel for production of gas turbine casings made from composite material, the mandrel including: an annular wall with a profile of an outer surface that corresponds to that of an internal surface of the casing to be produced; two side plates, with profiles that correspond to those of external casing flanges to be produced; and a removable device for clamping a layer having a fibrous texture, which is wound around the mandrel.
