The patent filed by Leonardo SpA describes a method for manufacturing a stiffened panel for an aircraft. The process involves arranging a skin of pre-preg composite material on a curing surface, positioning pre-formed stringers with an open cross-section on the skin, and using mandrels to cover specific portions of the stringers. The skin and stringers then undergo a co-curing process in an autoclave with a vacuum bag to cure the components effectively.
Additionally, the method includes steps such as arranging caul plates on uncovered portions of the skin, using secondary curing flaps between mandrels, and utilizing specific materials like bismaleimide or epoxy resin with carbon, glass, or Kevlar fiber reinforcement. The resulting stiffened panel consists of the skin and stringers, which can have various cross-section shapes like T-shaped, double-T, H-shaped, or Z-shaped. The patent also specifies the maximum thickness of the mandrels and materials used in the process, ensuring the quality and structural integrity of the final aircraft panel.
