There's this stuff that people have been using for centuries in a wide variety of applications. It comes in sheets and strips of various thicknesses, can easily be cut to shape, and is pretty strong. Usually it's rather flexible, and can be treated to be made more flexible or hard and rigid. It takes glues well, and can also use mechanical fasteners (rivets, screws, etc.)
