NDT (Non Destructive Testing) Study Guide & Complete Fundamentals Revision Notes
True or False? Parts or items inspected by NDT are destroyed during the inspection process. -
ANS ✔✔False
List two types of ultrasonic methods used to inspect composite structures. - ANS ✔✔Pulse-echo
and Through Transmission
What type of composite structure can be inspected using a light table? - ANS ✔✔Thin fiberglass
What is a "tap test"? - ANS ✔✔Tap on a composite part and listen for a change in sound
List at least one limitation for "tap" testing. - ANS ✔✔Not good for deep damage.
Briefly describe how a pulsed thermography NDT system works. - ANS ✔✔The part is heated
up, as it cools down it is monitored for irregularities using a thermo camera.
True or Fase: The result of a tap test can affected by a change i hte structure of the item being
inspected. - ANS ✔✔True
Define a delamination. - ANS ✔✔A seperation of Plys.
Define disbond or debond. - ANS ✔✔A faliure to bond
Why is the dye penetrant method not suitable for composite NDT? - ANS ✔✔Because liquid can
damage the part
