Thermographic Detection of Artificial Flaws in Polymer Matrix Composite Panel

초록

The thermographic detection of artificial flaws on epoxy polymer matrix composites (PMCs) was performed using the infrared thermography method with a high-speed infrared camera. The pulsed thermography with flash lamp was used for the integrity evaluation of PMC panel. The spherical artificial flaws with different diameters and depths were prepared from the panel of glass fiber reinforced epoxy polymer matrix composites. In this investigation, the pulsed thermography was employed to develop a nondestructive evaluation tool for the detection of flaws in PMC panel.
