The present invention relates to a composite material panel (1) comprising a composite material skin (2) having two generally opposite surfaces (20, 21) and first stiffeners (30) extending over one of the surfaces (20) of the skin. Said panel is characterized in that it comprises supplementary stiffeners (31) that are arranged on the surface (21) of the skin opposite the one having the first stiffeners (30), said supplementary stiffeners moreover extending in a direction separate from that of the first stiffeners (30). The skin and the stiffeners arranged on each surface are preferably secured to each other by means of co-molding.

Stamping tooling for thermoplastic parts and method
A tooling for manufacturing by stamping parts made of thermoplastic material from a blank of the material. A hollow die is delimited by a bottom, side walls and an opening opposite the bottom, and a raised punch designed to cooperate with the die via the opening. The tooling includes at least one mobile element to cooperate with at least one recess placed in the bottom and/or side walls of the die, the recess allowing the passage of one part of the blank that is to be bent using the mobile element.
