Damage Detection in Sandwich Composite Materials
Summary
Researchers at Purdue University have developed a component inspection method that can locate subsurface damage in sandwich composite materials. Damage detection is achieved with a three-dimensional laser vibrometer that collects forced frequency response data on a component that is being excited by a piezoelectric actuator. Using this data, damage can be reliably detected throughout a component without having to remove it from its structure.
