- stereologic microscopy techniques;
The microstructure of a chemical vapor infiltrated SiC/SiC ceramic matrix composite is quantitatively characterized using standard two-dimensional destructive and three-dimensional non-invasive stereologic microscopy techniques. The three-dimensional data used for the quantitative analysis was collected using an X-ray tomographic microscope (XTM). The XTM creates a three-dimensional map of the linear absorption coefficient in samples of approximately 1 cm3. Phase volume fractions, densities, and surface area to volume ratios are reported. Also, features that can only be obtained by non-invasive three-dimensional characterization, such as number of pores per unit volume, true feature size, and shape, are reported. These parameters are critical to accurate modeling of composite fabrication and deformation properties.
