Abstract

Optical coherence tomography (OCT) is a non-destructive and non-contact technique that images microstructure within scattering media. In this work, the versatility of OCT for non-destructive evaluation is demonstrated through imaging of composite microstructure and damage. Imaging of composite microstructure is demonstrated through tomographic reconstructions of an epoxy/unidirectional E-glass composite and an epoxy/0-90° woven E-glass composite. Imaging of damage is shown by tomographic reconstruction of impact damage in a epoxy/unidirectional E-glass composite. The volumetric reconstruction of the composite is re-sliced along the thickness axis to reveal the propagation of cracks though the reinforcement layers. Advantages and limitations of OCT are discussed.
