Abstract: In this paper, the microstructure of the bond between cementitious matrix and multi-filament yarn is characterized using both experimentally and numerically. The 3D geometrical model is constructed using a sequence of SEM-images. The filament-matrix bond is characterized using filament-pull-out-tests. The bond behavior is investigated using the pull-out tests accompanied with acoustic emission analysis. Numerical models of a yarn pull-out are used to reproduce the damage process of the yarn during the loading
