Abstract
There is disclosed a method of manufacturing a fan blade for a gas turbine engine, the method comprising: providing a root insert comprising quasi-isotropic short fibre reinforced resin, providing a first sub-laminate of a fibre-reinforcement pre-form for the fan blade on a first mould surface, placing the root insert on the first sub-laminate at a position corresponding to a root of the fan blade, providing a second sub-laminate of the pre-form over the root insert and the first-sub-laminate, so that the root insert is at an intermediate position between the first and second sub-laminates; and applying heat and pressure to form the pre-form.
