Thermal Method for Depth of Damage Determination in Insulating Materials
Impact damage often may produce little visible surface damage, yet extensive subsurface delaminations, greatly reducing the load carrying capacity of the composite part . For large composite structures typical of aerospace applications, thermal NDE techniques have been shown to provide quantitative information regarding the area and depth of hidden damage in composite samples  . For a quantitative assessment of damage, where a noncontacting method capable of imaging large areas at a time is required, thermal techniques have some advantages.
