Porosity inspection system for composite structure with non-parallel surfaces

摘要

A method and apparatus for inspecting a composite structure. A thickness profile of a portion of a region of a composite structure is identified. The region has a cross-section with non-parallel surfaces. An estimated thickness for a location within the region and outside of the portion is identified using the thickness profile. An indication of whether the location has undesirable porosity is generated based on information about attenuation of response sound signals and the estimated thickness for the location.
