System and method for inspecting secondary bonds in laminated parts

Abstract

Disclosed herein is a method of inspecting a secondary bond of a laminated part. The method comprises positioning the laminated part within a sealed chamber. The method also comprises 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 comprises, 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 comprises determining a condition of the secondary bond based on the gradient of change of the surface profile of the laminated part.
