Computed Tomography (CT) is on its way to becoming the de facto standard for fibrous materials analysis. It provides full 3D details of the interior of your materials. CT also enables non-destructive analysis, which may be coupled with either in situ experiments or numerical simulations to assess the physical properties of materials.

This paper focuses on the distribution of individual fiber orientations within a material. Experts from Thermo Fisher Scientific highlight three unique approaches that may operate at different resolutions to provide insights about the fiber orientations.
