Abstract:
The reinforcement of concrete with composite technical textile creates a tensile load-bearing capacity. It allows the elimination of steel reinforcement and minimisation of concrete cover. Based on this, the concrete cover is designed with respect to the cohesion of reinforcement with concrete. By using of textile reinforcement very thin structures could be created. The aim of this paper was to determine the interaction conditions of carbon and basalt composite reinforcement in a matrix of epoxy resin with high performance concrete (HPC). The tensile strength of used composite reinforcement and the other mechanical parameters of HPC were determined by experimental tests. Experiments copied the production method of technical textiles. These two combinations of materials present the influence on the design of the structures with textile reinforcements.

Abstract:
A series of flexural tests were performed in order to investigate the effect of steel fiber reinforcement (SFR) in textile-reinforced concrete (TRC) plates. Some of the specimens were reinforced only with textile, some of them only with fibers, and some of them were provided with both textile and fiber reinforcement. The concrete matrix was a self-developed ultrahigh performance concrete (UHPC) mixture with a compression strength over 160 MPa. The tensile strength of the used textiles was around 1500 MPa for glass fiber textile and over 3000 MPa for carbon fiber textile. In case of fiber reinforcement, the concrete was reinforced with 2 vol% of 15 mm long and 0.2 mm diameter plain high strength steel fibers. The dimensions of the rectangular plate test specimens were 700 × 150 × 30 mm. The plate specimens were tested in a symmetric four-point bending setup with a universal testing machine. The tests were monitored using a photogrammetric measurement system with digital image correlation (DIC). The paper presents and evaluates the test results, analyses the crack patterns and crack development, and compares the failure modes. The results showed a general advantageous mechanical behavior of specimens reinforced with the combination of fibers and textiles in comparison to the specimens reinforced with only fiber or textile reinforcement.

Abstract:
Abstract Numerical simulation tools are increasingly used for developing novel composites and composite reinforcements. The aim of this paper is the application of digital elements for the simulation of the mechanical behaviour of textile reinforcement structures by means of a finite element analysis. The beneficial computational cost of these elements makes them applicable for the use in large models with a solution on near micro-scale. The representation of multifilament yarn models by a large number of element-chains is highly suitable for the analysis of structural and geometrical effects. In this paper, a unit cell generating method for technical reinforcement textiles, using digital elements for the discretization, is introduced.

This paper presents an experimental verification of impregnated textile reinforcement splicing by overlapping using tensile test of small textile reinforced concrete slabs before its using in the product. The specimen dimensions were designed 80×360mm and thickness approximately 18 mm. This specimen was reinforced using two pieces of impregnated flat technical fabric from carbon roving and epoxy resin. Two overlap lengths were designed using data from previous cohesion tensile tests and necessary anchoring length. The purpose of this experiment was experimental verification before flat reinforcement splicing by overlapping on the final product – furniture with textile reinforcement. This paper shows possible problems and complications in the anchoring of the textile reinforcements and in splicing by overlapping, the importance of the accuracy reinforcement position in the thin concrete cross-sectional area.

In this study, one reinforced concrete specimen and six textile reinforced concrete (TRC) specimens were produced to analyze the flexural behavior of steel-textile-reinforced concrete. The TRC specimen was manufactured using a total of four variables: textile reinforcement amount, textile reinforcement hook, textile mesh type, textile lay out form. Flexural performance increases with textile reinforcement amount, textile reinforcement hook type and textile reinforcement mesh type. The flexural performance was improved when physical hooks were used. Furthermore, textile reinforcement was verified as being effective at controlling the deflection.

Abstract:
Abstract The underlying process for the production of textile reinforced thermoplastics is the impregnation of dry textile reinforcements with a thermoplastic matrix. The process parameters such as temperature, time and pressure of the impregnation are mainly determined by the permeability of the reinforcement. This results from a complex interaction of hydrodynamic compaction and relaxation behavior caused by textile and process parameters. The foundation for the description and optimization of impregnation progresses is therefore the determination of the pressure-dependent permeability of fibre textiles. Previous experimental investigations have shown that the dynamic compaction behavior during the impregnation of fibre reinforcements with thermoplastics or thermosets can be successfully characterized. However, for most cases, an analytical representation has not been possible due to the complexity of the process. Although it may be possible to reproduce this behavior by numerical calculations, the results need to be confirmed by experiments. This paper lays the analytical foundation for building a scaled model system, based on the theory of similarity, to observe, measure, and evaluate the dynamic compaction behavior of textile reinforcements under controlled process conditions.

Abstract:
Demand for very thin concrete elements, which can’t be reinforced with usually used steel reinforcement, gave rise to a new type of non-traditional reinforcement with technical textiles in matrix of epoxy resin. This type of reinforcement together with concrete is called textile reinforced concrete (TRC). Composite reinforcement is very chemically resistant, so the concrete cover is proposed to regard the durability. It allows a significant saving of concrete and design of thinner elements. For TRC structures is used high performance concrete (HPC) with its fine grained structure and high compressive strength. Textile reinforcement and TRC in general are developed at the Faculty of Civil Engineering and the Klokner Institute, CTU in Prague.

Abstract:
The needs of environmental protection led to the introduction of composites based on the use of plastics reinforced with biodegradable materials or other easily accessible materials. The overall purpose of the research was to experimentally investigate the possibilities of using some accessible reinforcement materials. Textile based on plants fibers and glass fibers were used as reinforcement materials, while the matrix was a polymer type material. An empirical mathematical model was proposed to highlight the effect of the number of glass fiber reinforcements on the tensile strength. The determined mathematical empirical model and graphical representations highlight how the number of glass fiber reinforcements affects the modulus of elasticity of the composite materials.

Abstract:
Mechanical tests were performed at the Klokner Institute on samples of a textile glass reinforcement. These tests will be used for determining the modulus of elasticity of textile glass reinforcements and for assessing the maximal stress that the samples will withstand. Both of these quantities are required for further modeling of the structures and for designing elements made from textile reinforced concrete (TRC). The tests were carried out on a total of 10 samples made from a single piece of 2D net (produced by V. FRAAS, GmbH, Germany). The tests were carried out on AR-glass reinforcement (alkali - resistant glass) textile glass with 2400 TEX [g/km] fineness, which is often supplied with dimensions of 1 x 2 m. The first 5 samples were prepared in the direction of the warp (the direction of the load-bearing reinforcement), and the remaining 5 samples were prepared from the transverse direction (the direction of the weft). These samples were loaded by a constant force increasing up to collapse. Then the modulus of elasticity of the textile glass reinforcement and the stress at the strength limit were determined from the monitored data.

Abstract:
Development of extremely thin concrete structures and demand for extremely thin elements are the reason of using composite non-traditional materials as reinforcement. Steel reinforcement is not very chemically resistant and it limits the thickness because of the required concrete cover as protection. This is the reason why textile reinforced concrete (TRC) going to be very famous and modern material. TRC in combination with fine grain high performance concrete (HPC) allows a significant saving of concrete. Due to its non-corrosive properties of composite technical textiles it is possible to design very subtle structures and elements. TRC and HPC in general are developed at the Faculty of Civil Engineering and the Klokner Institute, CTU in Prague. This present paper investigates the cohesion influence of textile reinforcement on four point bending test. All small experimental panels were reinforced with the same 3D technical textile from AR-glass roving with different type of cover layer. Different conditions of interaction between technical textiles and HPC were ensured by modified surface using silica sand and silica flour.

Abstract:
Fibre reinforcement has been used to reinforce concrete members for decades. It has combined well with concrete to help control cracking and increase toughness and other properties such as corrosion resistance. The use of traditional fibre reinforcement has led to the development of a new material called textile reinforcement (multifilament continuous fibre) which can also be used as the main reinforcement instead of steel reinforcement. This study experimentally investigates concrete beams reinforced only with carbon textile material (TRC beams). The tensile strength of textile reinforcement and pull out strength of TRC were measured. Four-point bending tests were performed on 76 beams (small and large scale beams). Several parameters such as volume fraction and reinforcement layout were studied in order to investigate their effect on TRC beam behaviour. The results showed that with the correct layout and geometry of textile reinforcement, these reinforced concrete beams, providing they had sufficient cover thickness, would perform well. Also, the results confirmed that the bond between the concrete and textile reinforcement plays a vital role in TRC beam performance. The behaviour of the TRC beams was compared with that of the steel reinforced concrete (SRC) beams; a major advantage of the TRC beam was the reduced crack widths. This study finishes by proposing a design methodology for TRC beams. Guidance covers flexural design, predictions for moment-curvature, and predictions for crack width of TRC beams.

Abstract:
Hybrid systems with two or more fiber materials were used to combine the benefits of each fiber into a single composite product. Strength and toughness optimization of hybrid thin sheet composites has been studied extensively using combination of different fiber types with low and high modulus of elasticity. Hybrid reinforcement is more significant when the reinforcing structure is in fabric geometry. Fabric structure provides full control on the exact location of each yarn and its orientation in the composite during production, thus maximizes the reinforcing efficiency. A high-strength, high-modulus fiber primarily tends to increase the composite strength with nominal improvements in toughness. A low-modulus fiber expected to mainly improve toughness and ductility. Combination of two or more types of fiber can produce a composite that is both strong and tough as compared to a mono fiber composite. The purpose of the current work was to study hybrid warp knitted fabrics as reinforcement for cementbased composite, having AR (Alkali Resistance) glass and Polypropylene (PP) as the reinforcing yarns. The examined ratios between the two different yarns were 0:100, 25:75, 50:50, 75:25, 100:0 (glass: PP, by percentage). It was found that in the hybrid system, the fracture mechanism is a superposition of the mono systems, and the tensile behavior is a combination between the two materials.

Abstract:
Dans plusieurs industries, les composites 3D sont largement utilisés pour fabriquer les pièces composites épaisses et complexes. La technologie de piquage permet de lier des renforts secs ensemble ou de renforcer les composites dans l’épaisseur grâce à des fils structuraux. Cette thèse est consacrée au développement de cette technologie et à l'analyse de l'influence des paramètres de piquage sur les comportements de préformage et les propriétés mécaniques de la préforme et du composite piqués.Le procédé de piquage est décrit dans la thèse. La configuration d'équipement est conçue pour réaliser ce procédé. Les paramètres de piquage peuvent être contrôlés par l'utilisateur. L’influence de la profondeur de piquage sur les propriétés mécaniques des 3D préformes renforcées par le piquage est analysé. Des 3D échantillons composites sont piqués avec des profondeurs de piquage variées. Les résultats d’essais mécaniques en traction et l’analyse microscopique sur la section transverse de l’éprouvette montrent que la profondeur influence fortement les performances mécaniques des composites. Le contrôle de ces paramètres est indispensable pour optimiser l’utilisation du piquage et améliorer les propriétés des renforts assemblés. Les comportements de préformage du renforcement piqué dans le procédé d'emboutissage hémisphérique sont aussi analysés. L'influence des fils de piquage sur l’avalement des plis, le glissement entre les couches et le phénomène de plissement lors de la formation est démontrée. De plus, les orientations du fil de piquage ont affecté les résultats de formage, qui ont conduit à un défaut de désalignement dans la zone où le cisaillement dans le plan est fort
Three-dimensional fabrics are widely used in several industries to manufacture thicker and more complex composite parts. Tufting technology is employed to bond dry reinforcements together or to reinforce the composites in the thickness by structural yarns. The thesis is dedicated to the development of tufting technology and the analysis of the influence of tufting parameters on preforming behaviours and mechanical properties of tufted preform and composite. The tufting process and the self-designed equipment configuration are described in detail in the thesis. The tufting parameters can be completely controlled by user. Influence of tufting length through the thickness on mechanical properties of 3D tufted preform and composite is analysed in this study. 3D composite samples are prepared with varied tufting length. Tensile tests are carried out to determine the influence of the tuft length on the mechanical performance of tufted samples. The tensile results and microscopic analysis on the cross section of 3D specimen show that the tuft length strongly influences on the mechanical properties of composite. Therefore, the control of these parameters is necessary to optimize the tufting process and thus improve the mechanical performance of assembled thick reinforcements. The preforming behaviours of tufted 3D reinforcement in the hemispherical stamping process are also analysed. The experimental data demonstrates the influence of tufting yarns on the material draw-in, interply sliding, and winkling phenomenon during forming. Furthermore, the orientations of tufting yarn affected the forming results, which leaded to misalignment defect in the zone of strong in-plane shear

Abstract:
Multilayer composite materials have a high tendency to interlaminar delamination when they are subjected to out-of-plane loading, because of their low-stiffness in the through-thickness (T-T) direction. The main aim of this research was to improve the interlaminar fracture toughness (IFT) of textile composites by using stitching as a T-T reinforcement technique. The intention was to provide greater delamination resistance and also to enhance the interlaminar fracture toughness between adjacent layers. In this research, E-glass 2x2 twill weave structure fabric layers and an epoxy resin were chosen as the base materials. Three different types of stitching; including the commonly-used modified lock-stitch and orthogonal-stitch (OS) geometries, the single-yarn orthogonal-stitch (SOS) and a newly-developed double-yarn orthogonal-stitch (DOS), as well as five different stitch densities were used to reinforce the multilayer preform lay-ups. The resin infusion moulding method was used to manufacture the E-glass/Epoxy 3D textile composites. The effect of stitched reinforcement on the Mode I-IFT mechanism was examined by performing double cantilever beam (DCB) tests and the Mode II-IFT mechanism by performing four-point bend end-notched flexure (4ENF) tests, respectively. Optical microscopy and scanning electron microscopy (SEM) imaging techniques were used to study the fracture surfaces of the stitched composite specimens, to assess the improvement in IFT mechanisms imparted by the stitched reinforcement used. The effect of stitching was analysed by comparing the various stitching geometries, stitch densities and the mechanical properties highlighted by the Mode I-IFT and Mode II-IFT results. It was found that the use of the novel double-yarn orthogonal-stitch (DOS) reinforcement allied with the use of high stitch densities gave the greatest improvement on both Mode I-IFT and Mode II-IFT tests. Moreover, in every case, the use of DOS and high stitch densities gave a significant improvement of 74.5% in Mode I-IFT and 18.3% for Mode II-IFT tests when compared with unstitched samples. It has been shown that the novel DOS stitch geometry yields significant benefits over established stitching techniques in respect of stitched reinforcement for laminated composite preforms. Besides this, the double column 5x5 mm stitch pattern reveals the highest delamination resistance performance among all the stitching formations tested for Mode I-IFT and II-IFT.

Abstract:
Aerospace structural components made from polymer matrix composites (PMCs) offer numerous advantages. Their high stiffness and high strength combined with low densities enable lower fuel consumption coupled with higher payloads. As a result, PMCs provide an important economic advantage over typical metallic airframes. Textile reinforcements for PMCs are made by assembling reinforcement fibres, typically carbon. Then, the textile reinforcements are typically cut into smaller pieces, stacked, draped and assembled into a dry assembly called a preform, the shape of which generally approaches that of the PMC part to be made. This manufacturing process is labour intensive and expensive. Novel thick, net-shape, drapable, high vf textile reinforcements used toward manufacturing aerospace PMCs are being developed at the University of Ottawa. The technology enables the manufacturing of flat, drapable multilayered near net-shape preforms. The bending and in-plane shear behaviours of such novel thick reinforcement textiles was investigated to understand and define the behaviour of such thick fabric reinforcements when formed into required shapes. A bending apparatus was developed for investigating the bending behaviour of these novel thick reinforcement fabrics and an articulated frame shear rig was used for investigating the in-plane shear behaviour. A non-destructive inspection method using infrared imaging was used for investigating and identifying flaws and defects in these thick, dry textile reinforcements, aiming at increasing the quality and reproducibility of the final PMC parts made from these reinforcements.

Ce travail de thèse est consacré à l'étude des renforts textiles techniques 2D à l'échelle mésoscopique. La méthode des éléments finis est utilisée pour résoudre un problème aux limites, fortement non linéaire, dans le domaine du renfort fibreux. Deux nouveaux modes de déformations pour le comportement des mèches de renforts ont été développés et caractérisés. Le premier mode est la compression longitudinale, qui permet de traduire la faible rigidité des mèches lorsqu'elles subissent une dilatation négative dans le sens des fibres. La relation conflictuelle sur le plan numérique entre la rigidité en tension, très forte, et la rigidité en compression longitudinale, très faible, peut être résolue via trois méthodes : réduction du pas de temps critique, addition de la contribution en tension ou avec une nouvelle stratégie pour l'actualisation du champ de contrainte. Le second mode de déformation est la dilatation transversale des mèches considérée comme conséquence directe de la compression longitudinale. Ce phénomène d'expansion de matière dans les directions transverses peut être observé avec un essai de compression longitudinale in-situ sous tomographie X et est communément ignorer. Un protocole expérimental a été mise en place pour mesurer cette dilatation transversale des mèches et un coefficient de Poisson a pu être caractérisé par identification inverse. Une campagne expérimentale a permis d'identifier les paramètres matériau du modèle mésoscopique et les résultats de simulations sont comparés aux images issues d'essai mécanique in situ sous tomographe
This thesis is devoted to the mesoscopic study on the performance of textile reinforcements. F.E. simulation is carried out on a mesoscale model for the fibrous material, based on which two kinds of new deformation modes are developed. The first one is a longitudinal compression mode, which is used to reflect the small stiffness when the yarn is compressed longitudinally. The incompatibility problem between the small longitudinal compression stiffness and the large tension stiffness are solved by three different strategies: constraining the critical step time, adding the nonlinear tension part, or using a new strategy to update the stress. The second one is transverse expansion mode that could reflect the influence from longitudinal deformation to transverse deformation. This deformation could be found in tomography view but was ignored by the former researches. An experiment is designed to measure the expansion magnitude, and the geometrical inverse fitting process is applied to measure the value of the longitudinal-transverse Poisson ratio. The parameters of the mesoscale model are measured by a series of mechanical experiments and the simulation results are verified by the tomography methodology

Abstract:
The present research aims to develop a novel technique for creation of composite riot helmet shells with reinforcing fibre continuity for better protection against low velocity impacts. In this research an innovative, simple and effective method of making a single-piece continuously textile reinforced helmet shell by vacuum bagging has been established and discussed. This technique also includes the development of solid collapsible moulding apparatus from non-woven fibres. Angle-interlock fabric due to its good mouldability, low shear rigidity and ease of production is used in this research. Several wrinkle-free single- piece composite helmet shells have been manufactured. Low-velocity impact test on the continuously reinforced helmet shells has been carried out. For this purpose an in-house helmet shell testing facility has been developed. Test rig has been designed in such a way that the impact test can be carried out at different locations at the riot helmet shell. Low-velocity impact test has been successfully conducted on the developed test rig. The practical experimentation and analysis revealed that the helmet shell performance against impact is dependent on the impact location. The helmet shell top surface has better impact protection as compared to helmet shell side and back location. Moreover, the helmet shell side is the most at risk location for the wearer. Finite Element models were created and simulated in Abaqus software to investigate the impact performance of single-piece helmet shells at different impact locations. Models parts have been designed in Rhinoceros software. Simulated results are validated by the experimental result which shows that the helmet top position is the safest position against an impact when it is compared to helmet back and helmet side positions.

Abstract:
Textile reinforced concrete (TRC) is an innovative composite material, which is being intensely and practice-oriented investigated on national and international level. In the last few years this material has gained increasing importance in the field of civil engineering. In the context of the collaborative research project SFB 532 at the RWTH Aachen University, research was carried out to understand and to predict the behaviour of different yarn structures in fine grained concrete. Based on the results, innovative commingling yarns were made of alkali-resistant glass fibres and water soluble PVA. These hybrid yarns have an open structure, which improves the penetration of the textile reinforcement by the concrete matrix. Hence, the load bearing capacity of TRC structural elements was significantly improved. This paper presents a technique for the production of such commingling yarns for concrete applications. The mechanical properties of the new yarns are determined due to tensile stress tests. The bond behaviour of the commingling yarns was investigated by pull-out- and tensile stress tests on TRC-specimens. The results of the different tests are being presented and briefly discussed.

Die kontinuumsmechanische Untersuchung der Lastübertragungsmechanismen zwischen den Rovings im textilbewehrten Feinbeton trägt wesentlich zum Gesamtverständnis des mechanischen Verhaltens des Verbundmaterials bei. Neben der Erfassung der gegenseitigen Beeinflussung sich kreuzender Rovings erfordert insbesondere die mechanische Modellierung und numerische Simulation von Bewehrungsstößen und Endverankerungen die Kenntnis dieser Übertragungsmechanismen. Die numerischen Simulationen sollen u. a. zeigen, welche Endverankerungslängen und welche Übergreifungslängen an Bewehrungsstößen erforderlich sind und wie die Querbewehrung die Rissbildung beeinflusst
This paper concerns with the investigation of stress transfer mechanisms between yarns and concrete matrix and their influence on the overall behavior of textile reinforced concrete (TRC). This investigation considers textile reinforcement splices and textile reinforcement development lengths and carried out by means of Finite-Element simulations and fracture mechanic approaches. A first modeling procedure is made towards analyzing and investigating the damage mechanisms in TRC specimen under tension loading which are mainly characterized by matrix cracking and yarn pullout. This modeling approach allows for considering the yarn crack bridging which is a main characteristic behavior of TRC. In the same manner, 3D Finite-Element models are conducted for calculating the required reinforcement development lengths and the reinforcement overlapping lengths. The conducted approach takes into account different damage mechanisms observed in the corresponding experimental investigations which are also used for calibrating the modeling procedures. Moreover, the presented approach covers a wide range of required textile reinforcement overlapping lengths and development lengths and provides the corresponding ultimate loads

Abstract:
When strengthening reinforced concrete slabs with textile reinforced mortars (TRM), the “correct” consideration of the global bond behaviour between textile and cementitious matrix is identified as the main challenge in determining the most appropriate global analytical model. The first model evaluated here is based on classical assumptions for structural concrete design. The second model, as another extreme assumption, is completely neglecting textile bond in the cracked zone, thus assuming it as unbonded, end-anchored, external reinforcement. The third model is based on the simplifying assumption of the textile reinforcement being only significantly activated when the internal steel reinforcement is yielding. Analytical results from these approaches are compared to a database containing more than 130 test results reported in literature, and are statistically evaluated.

Abstract:
Composite textile reinforcement draping simulations aid in determining the processing conditions for a quality part and in finding the positions of the fibers after forming. This last point is essential for the structural computations of the composite part and for resin injection analyses in the case of LCM processes. Because the textile composite reinforcements are multiscale materials, continuous (macro) approaches and discrete (meso) approaches that model the yarns have been developed. The finite element that is proposed in this paper for textile fabric forming is composed of woven unit cells. The mechanical behaviour of these is analyzed by 3D computations at the mesoscale. The warp and weft directions of the woven fabric can be in an arbitrary direction with respect to the direction of the element side. This is very important in the case of multi-ply deep drawing and when using remeshing. The element is efficient because it is close to the physics of the woven cell while avoiding the very large number of unknowns in the discrete approach. A set of validation tests and forming simulations on single-ply and multi-ply fabrics is presented and shows the efficiency of the approach.

Abstract:
Variability in fiber architecture and content introduces randomness in transport and mechanical properties of textile reinforcements and composites. Assessment of robustness of both manufacturing processes and composite parts require to link fabric variability to dominant properties. Irregular injection flow patterns or defects in the final products often occur due to the high variability in the fibrous media. Therefore, manufacturing robustness and part reliability have to be studied to avoid trial and error procedures. This study focuses on spatial variability in the fiber volume fraction and architecture and their influence on permeability of fiber reinforcements and mechanical performance of textile composite, relating these important properties to variation in reinforcement architecture. Methods to capture experimentally and model numerically the fabric randomness are presented and illustrated on typical non-woven fabrics. An efficient numerical approach is presented for the simulation of mold filling process with random fibrous permeability as input. Numerical examples for different injection schemes are presented to demonstrate the ability of the current approach in predicting the variability in mold filling results.

Abstract:
<p>The bond behaviour of concrete specimens with carbon textile reinforcement was investigated in the presented research programme. Pull-out specimens were cast from self-compacting concrete with expansive admixtures and in this way chemical prestress was introduced. The aim of the research was to compare bond behaviour between prestressed specimens and non-prestressed control specimens. During pull-out tests, the pull-out force and notch opening were measured with a load cell and laser sensors. Further, bond - slip and pull-out force - crack width relationships were drawn and compared for prestressed and non-prestressed specimens. Chemically prestressed specimens reached 24% higher bond strength than non-prestressed ones. It can be therefore concluded, that chemical prestressing positively influences the bond behaviour of concrete with textile reinforcement and thus better utilisation of its properties can be provided.</p>
