Abstract: The composite of a concrete matrix combined with technical textiles is investigated for several years now in the Collaborative Research Centre 532 (SFB 532) at RWTH Aachen University. The anisotropic properties of the material and the thin concrete layer lead to a spalling effect under high tensile load. The experimentally observed failure patterns are first classified and the performed experiment design is explained and discussed. A variety of tensile tests provided the basis for numerical analysis of the effect. The applied numerical model was designed in order to capture the initiation and propagation of longitudinal cracks leading to the separation of concrete from the textile fabrics. In consequence an experimental method was developed in order to confirm the numerically identified failure mechanisms. The paper presents the study of spalling based on both experimental and numerical investigations.
