DEFECT DETECTION IN WIND TUBINE BLADE COMPOSITE BY USING INFRARED THERMO GRAPHY

摘要

This study was conducted to investigate the nondestructive infrared-thermography assessment of composite materials for wind power blades, by simulating defects likely to occur during the manufacture and operation of blades and designing artificial quantitative-sized defects. Through the optical-infrared thermography, this study was able to detect void defects and even inclusion defects inside GFRP, a blade material.
