Low Energy Impact Detection on Carbon Fiber Reinforced Materials

摘要

Impact damages, even of small magni-tude, affect the mechanical properties of a composite material by reducing its structural integrity. Low energy impacts are not always visible to the naked eye, and they need to be accurately localized for safety and quality reasons. The results of low energy impact detection (0.5-6.0 J) on carbon fiber reinforced materials, carried out with four different NDT techniques— visual, infrared, X-rays, and eddy current—are presented in this paper.
