Abstract
A method of inspecting a secondary bond of a laminated part includes positioning the laminated part within a sealed chamber. The method also includes reducing a pressure within the sealed chamber to below a pressure outside the sealed chamber when the laminated part is positioned within the sealed chamber. The method further includes, when the pressure within the sealed chamber is reduced to below the pressure outside the sealed chamber, measuring a gradient of change of a surface profile of the laminated part. The method additionally includes determining a condition of the secondary bond based on the gradient of change of the surface profile of the laminated part.
