Abstract
Non-Destructive Testing (NDT) methods are essential for assessing the integrity and reliability of composite materials without causing damage. Composite materials are widely used in industries such as aerospace, automotive, and civil engineering. Therefore, the demand for advanced inspection techniques has increased. This article provides an overview of various NDT methods, including Visual Testing (VT) and Visual Inspection (VI), ultrasonic testing (UT), infrared thermography (IRT), and acoustic emission (AE). The advantages, limitations, and applications of these techniques are discussed. Their role in detecting defects such as delaminations, porosity, and fiber breakage observed in composite structures is highlighted.
