Description
High power halogen lamp induced multimodal radar thermography techniques for thermal nondestructive testing uses linear frequency modulated pulse or continuous thermal flux excitation and pulse compress matching filtering characteristic extraction, which provide a novel approach for rapid detection and tomography. In this present investigation, high power halogen lamp induced multimodal radar thermography was proposed to detect the impact damage of thermoplastic matrix fiber metal laminates (TFMLs). Initially, the principle of multimodal radar thermography and time/frequency characteristic extraction algorithms were introduced. Furthermore, TFMLs were manufactured using a one-step hot press compression molding process, meanwhile, low-velocity impact tests were performed for TFMLs specimens using a falling dart impact testing machine. Subsequently, water immersion ultrasonic imaging, X-ray detection and multimodal radar thermography were employed to detect the TFMLs impact damage, respectively.
