A method of preparing samples of a E-glass-epoxy composite material for moscopic examination thereof comprising the steps of first rough grinding the sample to produce a flat surface, fine grinding the sample in a series of grinding steps, each step accomplished with a finer grit of fine grinding material to obtain a relatively flat, scratch-free surface and then polishing the sample in a single polishing step to produce a sample with a scratch-free polished surface.
