A composite sandwich panel comprising:
- at least one web disposed between an inner skin and an outer skin, each skin being made from a composite material from a plurality of fibrous plies,
- wherein part of the structural plies constituting the inner skin and the outer skin each extend at least partially through the web, at an interrupted zone of the latter, so as to form, together, at least one through-reinforcement extending from the inner skin to the outer skin of the composite sandwich panel, and
- wherein the through-reinforcement comprises a plurality of first plies and a plurality of second plies, the plurality of first plies and the plurality of second plies each being independent from remaining plies among the plurality of fibrous plies, the remaining plies being excluded from the through-reinforcement.
