Testing of Composite Materials Using Advanced NDT Methods

Today modern industry make very extensive use of various composite materials. Because of complexity of such structures, abilities of commonly used NDT methods sometimes are not sufficient. More advanced techniques should be utilized. In this paper both T-Ray (terahertz radiation) and low energy DR (Digital Radiography) methods are compared for the purposes of various composite materials evaluation. Different types of tested materials (glass fiber and carbon fiber composite structures) and defects such as delaminations will be analysed.
