摘要：Multifilament yarns made of alkali-resistant glass are used as reinforcement element in textile reinforced concrete. To analyse the bond between concrete-matrix and yarn, cross-sections of a specimen are successively taken by a scanning electron microscope (SEM). Positions and diameter of the filaments are detected by image analysing methods in each cross-section. For the reconstruction of the yarn structure (third dimension) the filament-positions are matched between the different cross-sections by using measured distances of the cross-sections. Transforming methods like an iterative closest point set (icp) algorithm and a kalman-filter are used to find the right matches. The bond area, which is represented by the contact area of concrete and filament, is detected after an idealisation of the image in three types: filament, concrete and pores. The section around each filament is tested of bond areas. The locations of the bond areas are interpolated between the cross-sections, so that a kind of canals of bond are generated, which visualizes the spatial bond characteristics
