Abstract
A method of forming a fan blade includes the step of positioning a piece of low density filler in a cavity of an inner exposed surface of a fan blade body. An upper surface of the piece of low density filler is located above the inner exposed surface of the fan blade body, and the low density filler has a density lower than a density of a material of the fan blade body. The method further includes the steps of positioning the fan blade body in a lower die of a press and applying pressure to the inner exposed surface of the fan blade body with an upper die of the press to compress the low density filler such that the upper surface of the piece of low density filler is approximately flush with the inner exposed surface of the fan blade body.
