Abstract
An aircraft panel is disclosed having a ply of composite material, the ply of composite material curved around an axis such that a free end of the ply extends more than 180 degrees around the axis and defines a wall of a channel for receiving a hinge member of an aircraft component.
Claims15
An aircraft panel having an upper surface and a lower surface, comprising:
- an inner ply of composite material having a free end,
- wherein the inner ply of composite material is curved around an axis such that the free end of the ply extends more than 180 degrees around the axis defining a wall of an elongated channel opening along the axis and for receiving a hinge member of an aircraft component,
- at least one continuously extending surrounding outer ply of composite material in a laminated arrangement with the inner ply of composite material,
- wherein the at least one continuously extending surrounding outer ply forms
- the upper surface of the panel,
- a transition portion,
- a curved portion that curves around the axis and continuously extends to the transition portion,
- wherein the transition portion extends to the lower surface of the panel, and
- wherein the outer ply extends longitudinally along an entire length of the lower surface of the panel.
