A stiffened panel made of a composite includes a skin and at least one stiffener having a more or less closed volume. In order for the fibres of the composite to be held in place during fibre deposition and during pressure application while the resin of the composite is being cured, a moulding core is placed between the fibres at the position of the more or less closed volume of the stiffener. The moulding core includes a flexible bladder filled with a granular solid material, the thermal expansion coefficient of which is close to that of the composite used to produce the stiffened panel. The pressure in the bladder is increased before the composite is cured, so as to compensate for the forces applied for compressing these fibres during production of the panel.

An etchable plate-shaped material is used as a vacuum suction pad 31. On one surface thereof, a large number of independent protruded portions and recessed portions are formed to provide a suction part 33b. Further, a periphery of the suction part is annularly formed to provide an airtight part 33a.
