A method of manufacturing a hollow component (130), such as a fan blade for a gas turbine engine, comprises the steps of: (a) providing first (112) and second (116) panels and a membrane (114); (b) providing a stop-off material on at least one of the first and second panels and the membrane to define regions where no diffusion bonding is to take place; (c) assembling the panels (112,116) and the membrane (114) together so the membrane (114) is between the panels (112,116); (d) diffusion bonding the panels (112,116) and the membrane (114) together. The method is characterised in that when assembled in step (c) the membrane (114) does not extend to at least one edge (144) of the first and second panels (112,116) , so that in that region the first and second panels are diffusion bonded directly to each other. A hollow component formed by the method described above is also disclosed. |
