Products that exhibit some kind of collapse may cause serious problems for end-users. This can for example be fiber-based materials, where the fibers can fall in on themselves due to changes (with time) in their microscopic network. These failures or changes can be revealed through 3D X-ray techniques, which can accurately show e.g. fiber orientation, length, directionality, and possible changes. The techniques thus offer supplementary information – and “extended workbench” – that may be highly useful for the development of more durable products.
