In this article, with the demand of composite sandwich NDT, 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.
