Vibrothermographic NDE of Fiberous Composites
Is Version Of
Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.
This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.
Vibrothermography refers to the process of mapping the temperatures on the surface of a component while the component is undergoing forced mechanical vibration. Damaged zones in a polymeric fiber reinforced composite more efficiently convert kinetic energy to heat. Hence, at certain frequencies, delaminations and other damage appear to a scanning infrared camera as hot zones.
