| Abstract: | Principle of infrared thermal wave non destructive evaluations (NDE) is presented. Debonding flaws of aluminum honeycomb core composites and foam core composites are inspected by an infrared thermal wave imaging system. The results show that the NDE method is rapid, effective and intuitive for detection of debonding flaws in these composites. A mathematic model is founded to analyze thermograms of composites debonding flaws. It is simple and useful to analyze the results with this model theoretically. |
