“3D computational simulation and experimental validation of structured materials: Case studies of tissue papers

The development and optimization of structured materials, such as tissue paper benefit from modeling strategies that take into consideration its structural hierarchy at the fiber levels. use an innovative three-dimensional voxel approach to model both 3D structure were validated by comparison computational structures with laboratory-made structures. main goal this work was obtain a implementation adapted for products. fibers modeled in according their dimensions, produced them characterized using Representative Elementary Volume (REV) image analysis tools. This methodology made it possible morphology, flexibility, collapse, resulting thickness, porosity, relative bonding area, coverage, among other properties. experimental design plan included production characterization isotropic laboratory basis weights 20, 40, 60 g/m2 different eucalyptus beating degrees. With aid these advanced tools, mathematic models predictive capacity properties softness, strength, absorption can be developed.
