This book presents the study of the temperatures at which delamination starts to occur in different samples of Carbon Fibre Reinforced Polymer (CFRP). The sensitivity of different Non-Destructive Testing (NDT) techniques of Ultrasonic Testing and Active Thermography on heat-treated composite materials would also be discussed. The composite specimens are heated by a heat gun for a time interval of 35 minutes. The process is repeated with different temperatures, maintaining the time interval. Ultrasonic Testing and Thermography will then be conducted to determine the extent of the damaged...
