Within hollow structures, such as blade structures in a gas turbine engine, traditionally rigid girdered reinforcement has been utilised to define structure and shape. Such rigid definition can inhibit utilisation of damping fillers within the hollow structure. By providing a web former comprising spaced bond areas suspended upon angled interconnecting membranes a hollow structure is achieved which is flexible and can be used in conjunction with a damping filler to achieve desired performance. The web former supports skins defining the shape and takes some load such that the damping filler does not separate within the hollow structure.
