The paper at hand presents an investigation of the tensile behavior high-strength, strain-hardening cement-based composites (HS-SHCC), reinforced with a single layer continuous, two-dimensional textile made ultra-high molecular weight polyethylene (UHMWPE). Uniaxial tension tests were performed on bare UHMWPE textiles, plain HS-SHCC, and hybrid fiber-reinforced composites. bond properties between yarns surrounding composite investigated in single-yarn pullout experiments. In order to assess...
Abstract Despite significant weight and performance advantages over metal parts, today’s demand for fiber-reinforced polymer composites (FRPC) has been limited mainly by their huge manufacturing cost. The combination of dry textile preforms low-cost consolidation processes such as resin transfer molding (RTM) appointed a promising approach to FRPC manufacture. This paper presents an advanced weaving technique developed with the aim establish more cost-effective system manufacture FRPC. 2D...
Concrete is extremely vulnerable against impact loading due to its low tensile strength and pronounced brittleness. The application of thin strengthening layers, containing Textile Reinforced (TRC) Strain-Hardening Cement-based Composites (SHCCs) in a ductile cement-based composite, promising solution enhance the resistance existing concrete structures. Three-dimensional (3D) textile structures exhibit numerous advantages over two-dimensional (2D) ones, most importantly higher shear, bending...
Abstract Im Rahmen des DFG‐Graduiertenkollegs GRK 2250/1 „Impaktsicherheit von Baukonstruktionen durch mineralisch gebundene Komposite“ werden neuartige Verstärkungsmaterialien mit unterschiedlichen Faserbewehrungen entwickelt, die Widerstandsfähigkeit bestehender Konstruktionen gegen kurzzeitdynamische Belastungen deutlich erhöhen sollen. Des Weiteren adäquate Prüfkonzepte und Messverfahren für eine grundlegende Charakterisierung Beschreibung dehnratenabhängigen Materialverhaltens...
Abstract Ziel des seit 2017 durch die Deutsche Forschungsgemeinschaft (DFG) geförderten Graduiertenkollegs GRK 2250 ist interdisziplinäre Erforschung von Methoden zur Erhöhung Impaktwiderstands Bauwerken nachträgliche Verstärkung. Der vorliegende Beitrag gibt einen Einblick in GRK‐Forschung auf Strukturebene. Mineralisch gebundene Verstärkungsschichten wurden der dem Impakt abgewandten Bauteilseite untersucht. Als Material für diese Schichten kamen feinkörnige Matrices ohne und mit...
This research focuses on the electromechanical strain-sensing behaviour of steel wires fiber and composites scale. The properties are investigated by using a uniaxial tensile test with simultaneous electrical resistance measurement. Further, this work conducts comprehensive stress analysis textile reinforced concrete (TRC) specimen in quasistatic dynamic tests integrated 3D-weaving reinforcement as piezoresistive in-situ-sensors. results compared to optical strain measurements digital image...
