Comparison of X-Ray Micro-Tomography Measurements of Densities and Porosity to Traditional Techniques for Carbon-Carbon Composites

摘要

The porosity in carbonaceous materials affects many of their properties. For this reason, the characterization of this porosity is very important. Many diverse techniques have been utilized to characterize the pores in carbon materials. Some of these technique along with the use of X-ray micro- computed tomography (muCT) have been utilized in this study to provide significant insight into the pore structure of carbon-carbon composites. muCT is not only capable of providing information on the size, shape, and distribution of both open and closed pores in 3-dimensions but in conjunction with mercury porosimetry, it is also able to explain artifacts in the samples.
