Abstract

This dataset contains X-ray computed tomographic data of a ceramic matrix composite (CMC) single tow mini-composite specimen collected at four tensile load levels (40, 80, 120, 160 N). The specimen was prepared from Hi-Nicalon™ Type S (HNS) fibres with an average diameter of 12 microns (Nippon Carbon Co., Ltd., Tokyo, Japan), which were coated through a chemical vapor infiltration (CVI) process with boron nitride (BN). Subsequently the fibres were overlaid with a silicon carbide (SiC) matrix also applied via the CVI process. The sample was loaded in situ at the Advanced Light Source at the Berkeley National Laboratory in Beamline 8.3.2, where X-ray scans were collected at four tensile load levels, i.e., 40, 80, 120 and 160 N. Tomographic data collection was carried out in white light mode with photon energy of 43 keV, with 180 degree rotation and 1024 steps. The voxel size in reconstructions was 0.67 µm and image files were output as 32 bit.
