Abstract

A rapid, non-destructive technique called optical coherence tomography (OCT) is used to image the microstructure of an epoxy/e-glass composite. The raw OCT data is processed and converted to a binary image, and then input into a lattice Boltzmann simulation for permeability prediction. Calculated permeabilities fall within the experimentally determined range for the same fiber volume fraction. The effect of different image processing algorithms which convert the raw grayscale OCT image to a binary image is discussed.
