A review of non-destructive testing (NDT) procedures for the assessment of composites is given. The review takes into account the capabilities of the most popular techniques used in composite NDT applications, including Visual Testing (VT or VI), Ultrasonic Testing (UT), Thermography, Radiographic Testing (RT), Electromagnetic Testing (ET), Acoustic Emission (AE), and Shearography Testing, as well as the benefits and drawbacks of each technique. Additional techniques are categorised based on their inherent qualities and applicability. Typically, an NDT evaluator performs the evaluation using just one non-destructive test method. Using just one test technique is allowed if the scope of the job is simple. A mixture of several test methods is necessary because there are situations when a single test method does not give sufficient information about the material integrity Following that, approaches were grouped according to their inherent qualities and applicability. Non-destructive testing is frequently used in power plants, the aerospace, nuclear, military, and defence industries, as well as storage tank inspection, pipe and tube inspection, and the characterisation of composite flaw. The extent of NDT use for composite materials is the primary emphasis of this paper.
