Question: 1 / 1030

During a composite panel inspection using the rung test/tapping method, a dull thud may indicate:

Moisture content

Proper adhesion

Separation of the laminates

When performing a composite panel inspection, the rung test or tapping method is used to detect any separation or delamination between the layers of the panel. A dull thud during this test indicates that there is likely a separation of the laminates, meaning that the layers are not properly bonded together. It is important to address this issue as it can impact the structural integrity of the panel. Moisture content, proper adhesion, and no significant findings would not produce a dull thud during the rung test/tapping method.
