Composite Sandwich Structure Digital Tap Test Technology Research
the tap force time criterion theory of digital tap test was introduced. The portable tap test imaging system was designed. To different type and damage dimension sandwich structure
the tap test validate experiment was studied
and the NDT experiment results were discussed and analyzed. The experiment proves that the digital tap test technique can effectively detect the delamination and debonding defects of honeycomb and foam sandwich structures.
