Abstract
A core structure () for a composite panel for an aircraft, for example a door fairing for a landing gear bay, including a sandwich structure in which core cells () are sandwiched between first and second body sides (skins). The core cells are square or rectangular in shape and each have a void formed by cell walls (). The first and second body sides and the cell walls include laminated composite material of multiple layers. Drainage holes () in the cell walls form one or more direct drainage paths (P, P) for the flow of fluid from the core structure. The core cells include first and second sheets of cells reversibly mounted to each other, such that the void of each cell is formed in part by the first sheet and in part by the second sheet.
