This article presents a microscale modelling approach coupled with X-ray
computed micro-tomography for the evaluation of material properties of polylactic acid (PLA)
reinforced by birch pulp fibers under the effect of moisture. The results in terms of elastic
moduli and hygroexpansion deformation were found in good agreement with the measurements
taken at different levels of water uptake.

Use of micro-tomography for validation of method to identify interfacial shear strength from tensile tests of short regenerated cellulose fibre composites
Hajlane, A.; Miettinen, Arttu; Madsen, B.; Beauson, J.; Joffe, R. (Institute of Physics Publishing Ltd., 2016)The interfacial shear strength of short regenerated cellulose fibre/polylactide composites was characterized by means of an industry-friendly adhesion test method. The interfacial shear strength was back-calculated from ... -
Analysis of fluid flow through porous media based on x-ray micro-tomographic reconstructions

Effects of defects on the tensile strength of short-fibre composite materials
Joffre, Thomas; Miettinen, Arttu; Wernersson, Erik L.G.; Isaksson, Per; Gamstedt, E. Kristofer (Elsevier BV, 2014)Abstract. Heterogeneous materials tend to fail at the weakest cross-section, where the presence of microstructural heterogeneities or defects controls the tensile strength. Short-fibre composites are an example of heterogeneous ... -
