    초록 Two types of nondestructive evaluation (NDE) methods, such as infrared (IR) thennography and acoustic emission (AE) techniques, were used for the damage analyses during tensile testing of Nextel fiber reinforced Blackglas matrix composites. During tensile testing, AE sensors and an IR camera were used for in-situ monitoring of the progressive damages of the samples. AE provided the amounts of damage evolution in terms of the AE intensity and/or energy, and the IR camera was used to obtain the temperature changes during the test. Microstructural characterization using scanning electron microscopy (SEM) was performed to investigate the fracture mechanisms and modes of Nextel/Blackglas samples. Moreover, SEM characterization results provided the substantial evidence of failure behavior, and showed comparable results with NDE signatures.
