Abstract: Fabric reinforced cement based composites are a new class of sustainable construction materials with superior tensile strength and toughness. They demonstrate a significant improvement in the energy absorption capacity as compared to plain concrete materials and fiber reinforced composites. In this work we studied the dynamic behavior of cement composites reinforced with Alkali Resistant (AR) glass and polyethylene (PE) fabrics under high speed tensile loading. The dynamic material properties, including Young’s modulus, tensile strength, toughness, and maximum strain are obtained. Typical stress-strain curves representing the tensile behavior of individual composites were compared. A fairly uniform tensile behavior was clearly observed for these composites, demonstrating the reliability of the high-rate testing method for cement-based composites. The differences in tensile behavior of the composites were correlated with the different structure and mechanical properties of the fabrics. A multiple cracking behavior was observed for all the fabric-cement composites, indicating good stress transfer within these composites. Test results obtained in this study provide tools to design composite elements that are expected to resist extreme loading during their service life.
