“…Fibrous materials have found widespread application in the reinforcement of structural composites in recent years. 1 In the past, focus has been laid on textile fabrics made from continuous yarns and rovings. Unlike discrete particle and short-fibre fillers, textile reinforcement allows for the realization of high-performance yarns or rovings.…”

“…This combination has led to the formation of a fundamentally new class of structural materials -textile-reinforced concrete (TRC). 1,2 TRC finds diverse applications, ranging from a variety of architectural elements to load carrying reinforced concrete-based structural members. The main advantage of TRC is the minimal concrete covering required for textile fabric bonding.…”

“…Further, it has been noted that TRC exhibits different bond behaviour from that of steel-reinforced concrete owing to the inhomogeneous cross-section of rovings. 1 For the manufacturing of TRC, yarns or rovings are usually processed for warp-knitted 2D [12][13][14] and 3D 15 textile reinforcement structures. These textile reinforcements are embedded into fine-grained concrete with particle size <2 mm to absorb the applied tensile forces.…”

“…The parameters of the structure of the textile fabric, as well as the properties of its constituent yarns, affect the properties of the resulting concrete matrix. 1,10,12 Variation of these parameters can improve the adhesion to the concrete matrix and hence enhance the reinforcing effect. 12,13 For uncoated textiles, only the outer filaments are anchored in the cement matrix.…”

High-performance textiles are used for reinforcing concrete structural parts. This paper presents a technique for producing coated weft-inserted warp-knitted fabrics for concrete applications. Three types of reinforced fabrics differing in coating type and composed of alkali-resistant-glass rovings resulting in a cement composite matrix were produced. The investigated coatings include potassium silicate, carboxylated styrene butadiene rubber and epoxide. The mechanical properties of the developed fabrics and cement composites were determined according to the coating type. Thereafter, the mechanical performance of the warp-knitted reinforced fabrics was investigated using tensile tests. Finally, the properties of the composites were examined according to the coating type using a four-point bending test. The results of the characterization of the coated weft-inserted warp-knitted reinforced fabrics and cement composites based on them are presented and discussed. It is shown that the coating material has high influence on the composite properties. Samples with potassium silicate showed highest strength at the limit of proportionality, while samples with epoxide showed the highest flexural strength.

Carbon‐ und AR‐Glasfasern als Bewehrung für Beton sind korrosionsbeständiger als Stahl. In Form von Textilien aus Carbonfasern und AR‐Glas bilden sie in Kombination mit Beton den Werkstoff textilbewehrter Beton. Textilbewehrter Beton lässt sich im Vergleich zu Stahlbeton dünnwandiger in der Größenordnung weniger Millimeter ausführen, da er keine Mindestüberdeckung zum Korrosionsschutz der Bewehrung benötigt. Zudem sind Carbonfasern elektrisch leitend. Der Zusammenhang zwischen Dehnung und Änderung des elektrischen Widerstands der Fasern ermöglicht eine Bestimmung des Spannungszustands aufgrund der Widerstandsänderung. In Vorbereitung einer umfangreichen Grundlagenforschung wurden Versuche an unbeschichteten Carbongarnen im Beton durchgeführt. Es hat sich gezeigt, dass die Proportionalität zwischen Widerstandsänderung und Dehnung mit k‐Faktoren zwischen 1,5–3 bei Carbonfasern ähnlich der von Metall ist.

Conductive yarns are crucial for electrical connections in electronic textiles and are used in fabricating sensors, electrodes, and wearable communication devices. Challenges in conductive and elastic properties of conductive yarns, their durability and compatibility with existing manufacturing processes limit mass production and affordability of conductive yarn. This work investigates elastic, shell‐conductive, and non‐corrosive electro‐conductive yarns (ECYs) for textile‐based wearable electronics. The existing textile manufacturing processes (plaiting, coiling, and twisting) were used to fabricate different blend ratios of stainless‐steel conductive yarn and elastomeric yarn. The ECY samples were inspected for structural uniformity, conductive coverage, ability to be woven, thickness, and extensibility. The most promising ECY exhibited a breaking force of 10.87 N, a tenacity of 2.04 cN/tex, and an elongation at break of 61.1%, suitable for integration into e‐textiles where elasticity is required. ECY with conductive coverage of 85.36% provides better electrical connection points, while a thickness of 0.69 mm and linear density of 534 tex make it compatible with traditional textile manufacturing equipment. Our findings demonstrate that the fabrication method and input parameters significantly impact the properties of ECY, including their elasticity and conductive coverage. Utilising ECYs in fabric circuit boards, can enable improved smart wearables for sustainable and modular integration of electronic components.This article is protected by copyright.
