3D Porosity and Fiber Orientation in Ceramic Matrix Composite Preform
November 03, 2017
The porosity and fiber orientation of a partially densified Hi-Nicalon S ceramic matrix preform were analyzed using Robo-Met.3D®. Post processing segmentation was used to reveal the pore, matrix, and fiber distribution separately, with their volume percentages. Closed porosity not detectable in micro CT analyses, as well as anomalous fiber orientations, were uncovered.
