Abstract

Composite has become an important material in various industries. It is used widely in diverse applications such as aerospace, light and heavy industrials. Composite materials are currently a prominent topic in the industrial field, because they are lightweight, become less expensive and easier to manufacture, and have strong mechanical properties. Nondestructive testing (NDT) is one of the modern technologies used for inspection and evaluation of material integrity, it does not damage inspected components, either directly on the surface or deeply in the components. Phased Array Ultrasonic Testing (PAUT) is an advanced NDT technique that depends on multiple elements for detecting defects, with "phase" referring to time and "array" referring to elements. A PAUT system can be set from 16 to 256 elements, and each element can pulse separately. In testing, PAUT data is based on time and amplitude information derived from waveforms. These waveforms and the information extracted from them will commonly be presented in one or more of four formats: A-scans, B-scans, C-scans, or S-scans.
