title = "Heat induced damage detection in composite materials by terahertz radiation",
abstract = "In recent years electromagnetic Terahertz (THz) radiation or T-ray has been increasingly used for nondestructive evaluation of various materials such as polymer composites and porous foam tiles in which ultrasonic waves cannot penetrate but T-ray can. Most of these investigations have been limited to mechanical damage detection like inclusions, cracks, delaminations etc. So far only a few investigations have been reported on heat induced damage detection. Unlike mechanical damage the heat induced damage does not have a clear interface between the damaged part and the surrounding intact material from which electromagnetic waves can be reflected back. Difficulties a{\ss}ociated with the heat induced damage detection in composite materials using T-ray are discu{\ss}ed in detail in this paper. T-ray measurements are compared for different levels of heat exposure of composite specimens.",
