Thermographic method of detecting delamination in a composite part using ohmic heating by applying an electric current through the composite part itself
Thermographic method of detecting delamination in a composite part using ohmic heating by applying an electric current through the composite part itself
A method of detection of delamination in a composite part having a conductive layer. The method comprising the steps of passing a current through the composite part to cause ohmic heating of the part, removing the current from the part, detecting thermal images of the part as it cools over a specified time interval and viewing thermal images to identify areas of delamination.
