X-Ray Tomographic Study of Pore Volume Fraction in Samples of Polymer Composite Materials. Scanning and Reconstruction of Tomographic Data

A description of the X-ray tomographic studies of samples made of polymer composite materials for the purpose of quantitative determination of the pore volume fraction is presented. The tomographic examination includes two stages: scanning and image reconstruction. A subpixel scanning method was applied at the first stage to increase the image resolution. The corrections provided in the software of the tomograph were applied when reconstructing the image. The results of evaluating the volume fraction of pores obtained by subpixel and cylindrical scanning showed their complete convergence.
