Determination of local deformation in paper from 3D tomography data via pore network analysis
The 3D microstructure of paper recorded at micrometer resolution reveals the pore space available for transport in paper. When dry paper is exposed to water, the total pore space expands in volume even though the paper fibers double in volume at the same time. Yet it remains unclear how the pore space locally changes. To answer that, this project utilizes image analysis to map pore structure on pore networks. Monitoring pore networks associated to paper before and while being contact with water shall reveal whether water-induced changes can decisively affect transport.
