Numerical investigation on the mechanical behaviors of 2D woven composites under complex in-plane stress states

Using finite element method (FEM), the mechanical behaviors of 2D woven composites with different weave structures are investigated with considering the complex in-plane stress states. Periodic boundary conditions for arbitrary off-axis loading scenarios are established, and a progressive damage model based on Linde criterion is proposed, which is subsequently validated by the previous experiments. In addition, the failure envelopes predicted by classical failure criteria are compared to the results obtained by FEM. The effects of woven structures on elastic properties and failure behavior are also discussed, which demonstrates that the plain woven composites have inferior mechanical performance than twill and satin woven composites. Based on the assessment of the failure criteria, this study provides recommendations for selecting relevant failure criteria to anticipate mechanical properties under various loading conditions. The findings in this paper are expected to encourage the development of damage constitutive models and their engineering applications for 2D woven composites.

Effect of woven structure and aramid binder yarn on the flexural performance of carbon/aramid fiber hybrid three‐dimensional woven composites

AbstractThree‐dimensional (3D) woven textile‐reinforced composites have drawn much attention because of their specific geometries, improved composite interlayer strength, and impact‐resistance performance. In this study, three types of 3D woven structures with different binder‐yarn ratios and paths were designed based on a traditional dobby‐weaving loom with a special weft‐interlock structural design. Carbon/aramid fiber‐reinforced plastic (CAFRP) composites with carbon warp, weft, and aramid binder yarns, as well as carbon fiber‐reinforced plastic (CFRP) composites were reinforced using the three types of woven structures and consolidated with epoxy resin. The quasi‐static and dynamic flexural performance of these 3D woven composites were experimentally investigated using a three‐point bending test and a low‐velocity drop‐weight impact test. Nondestructive ultrasonic C‐scan and X‐ray microcomputed tomography were applied to characterize the failure mode of the impacted composites. Woven structure and aramid binder yarn with a coarse count have a coupling effect on the quasi‐static flexural performance of the 3D woven CAFRP composites. A larger volume combined with a smaller through‐thickness waviness degree of aramid binder yarn has a similar effect with a smaller volume combined with a larger waviness degree. Introducing aramid binder yarn in the hybrid composites lowered the quasi‐static flexural performance to a certain extent (0.28%–47.74% and 5.29%–49.63% for flexural modulus and strength, respectively) but increased the impact performance significantly (e.g., increasing 23.6%–92.7% peak‐load values under 6‐J impacts). A larger volume combined with a smaller waviness degree of the aramid binder yarn introduced in these woven structures contributed more to impact‐resistance and damage‐tolerance performance.

Factors of Weave Estimation and the Effect of Weave Structure on Fabric Properties: A Review

This paper provides a review of recent studies on the weave factor along with the effect of weave parameters and particularly the weave structure on various properties of woven fabric. The weave structure can be considered as one of the prime parameters that contributes to the dominant physical and qualitative properties of the woven fabric. This study analyzed not only the parameters that significantly influence the properties of the woven fabric, but also the weave factors for the estimation of the weave that were proposed by earlier scientists. This review paper highlights the impact of weave structure on the physical and mechanical, thermo-physiological and comfort properties, and some special application properties of woven fabrics. This work seeks to serve as a future reference for related research.

Effect of weave structure and yarn fineness on the coolness and thermal-wet comfort properties of woven fabric

It is difficult to meet the needs of multi-functional comfortable fabric through the single functional fibers on the market. The aim of this work was to develop a kind of summer comfortable woven fabric with coolness through the combination of different functional fibers. Blended yarn of bamboo and polyester with grooves was chosen as the warp yarn, which was responsible for moisture absorption and transportation. Nylon filament with a cross-section and fine-denier polyester filament was chosen to twist reversely as a composite weft yarn to provide the coolness function and moisture conduction for fabric. As a comparative weft yarn, polyethylene was chosen as another type of weft yarn. Twelve samples were prepared containing three structures. The effects of fabric structure, weft yarn composition and fineness on the coolness and thermal-wet comfort were evaluated and investigated, including thermal-physiological comfort properties, moisture management properties, the wicking effect and the drying performance. The result showed that the weave structure, weft yarn composition and fineness had a significant influence on the coolness and thermal-wet comfort properties. Fabric woven with plain weave structure contributed to heat dissipation and dynamic coolness. The float yarn in the 2/1 twill and mesh structure was beneficial to promote water transportation vertically. The results also suggested that polyethylene yarn was preferred for coolness fabric, but the liquid moisture management and drying performance of polyethylene fabric should be further improved.

Methods of increasing the stretchiness of cotton fabrics

In response to getting more stretch and elasticity from 100% cotton fibers as woven fabric not made from lycra or spandex yarns and so on. In this survey, the researcher examines the relationship between different spinning methods for Egyptian cotton using twill fabric structure under a variety of weave factors on different weft densities to study the stretch and recovery from cotton fiber. The dependencies of the weft yarn spinning method and weft density were established. The effect of weave structure was determined. It founded that stress on the yarn will relax as a function of time due to the viscoelastic character of textile materials.

Effect of Weave Structure on Comfort Property of Fabric

ABSTRACT The air permeability, thermal resistance, water vapor permeability, water absorption, and Stiffness were measured to determine the comfort property of the fabric. For this study, the plain, twill, and satin structures were produced from warp ring-spun yarn and weft open-end spinning yarns. Using ANOVA statistical analysis, the weave structures on the comfort properties of these fabrics were investigated. The finding of this study revealed that from plain to twill and satin structure the result leads to an increasing of Water Vapor Permeability, Water absorption rate, and air permeability. On the contrary, from plain to twill and satin the thermal resistance and stiffness of fabrics were reduced. Plain weave structure was superior thermal resistance and stiffness, whereas Satin weaves have higher air permeability, water vapor permeability, and water absorption rate.

Effect of weave structure on the slicing cut resistance of woven fabrics

Cutting processes using blades have found applications in many industries; for example, in garments, fiber–polymer composites, and high-performance fabric forming. In recent decades, the process of cutting the material using a robotic-controlled blade has raised concern about the value of the pressure and the cut force required for a certain type of woven fabric and the estimation of its value before the pressing and cutting process. A simple theoretical relation was established based on the fabric structure and yarn shear stress. The model formulation and experimental results to describe the basic theory of blade cutting fracture for woven fabric of different designs was derived. In this work, the experimental investigation of the effect of the fabric specifications, normal load, and the cutting speed on the cutting force was carried out, which indicates that the value of the specific cutting resistance of the fabric was found to be highly correlated with the fabric structure, warp and weft yarn count, Young’s modulus of the fabric, and fractional cover factors ratio ζ.

Studies on the Mechanical Characterization of Jute Fiber Reinforced Unsaturated Polyester Resin Based Composites: Effect of Weave Structure and Yarn Density

This paper represents a comparative study of the different weave structures of jute woven fiber reinforced unsaturated polyester resin (UPR) composites. The weave structures were selected as plain (1/1), twill (2/1), twill (3/1) and basket (2/2). Composites (50% fiber by wt.) were prepared by using hand lay-up technique. The mechanical properties such as tensile strength (TS), bending strength (BS) and impact strength (IS) of the composites were evaluated and compared. It was found that basket weave/UPR based composite showed the highest mechanical properties. The optimum value of TS, BS, TM, BM and IS of the composite were found to be 47 MPa, 80 MPa, 1.4 GPa, 4.8 GPa and 27 KJ/m2.To find out the effect of yarn density on mechanical properties of the composites, 2/1 twill structure was selected and found significant improvement in the mechanical properties with the increase of Ends/Inch (EPI) and Picks/Inch (PPI) in the fabric. Water uptake and degradation behavior in aqueous medium of the composites was also observed.

The effect of weave structure on the quality of inkjet polyester printing

In this study, the print quality of lines were investigated in warp and weft directions that were inkjet printed on various weave structures of polyester such as plain, 2/2 twill, 3/1 twill, 3/2 twill and 4/1 twill. In order to study the effect of weave structure on the quality of inkjet printing on polyester fabrics, lines having a width of 1 mm, 2 mm, and 4 mm were inkjet-printed and the print quality was measured as the line width. The quantitative analysis of lines width was performed by scanning the fabrics with a scanner. The obtained result showed that the weave structure is effective on the lines width and print quality, and the plain weave structure had the worst print quality in both directions. Also, the width of lines printed in the weft direction was more than lines printed in the warp direction which is possibly due to more density of warp than weft. The effect of weave structure and print direction on lines width and print quality was also confirmed by the analysis of variance (ANOVA) results. The image processing was shown that the ink spreading shape on the various fabrics is different and is affected by the weave structure and the print direction.

Mechanical and abrasive wear performance of woven flax fabric/polyoxymethylene composites

We report an investigation on the abrasive wear behaviors of flax fabric-reinforced polyoxymethylene (POM) composites. The effect of weave structure on the friction coefficient and wear rate of the composites varied according to the level of applied load and sliding speed. Incorporation of the flax fabrics could reduce the wear rate by as much as 4-fold at high load and high sliding speed conditions and could improve the mechanical properties of POM significantly. By careful choice of the weave structure, this low wear rate could be achieved without increasing the friction coefficient. The wear mechanisms of the composites were discussed in detail based on evidences from scanning electron microscopy. It was concluded that the formation of transfer film and the weave structure of flax fabric had an important impact on the wear performances of the composites.

Water uptake and degradation behavior in aqueous medium of the composites was also observed.

Analysis of Frictional Behavior of Woven Fabrics by a Multi-directional Tactile Sensing Mechanism

The frictional property of woven fabrics is one of the prominent surface characteristics which influence the performance of fabrics in a variety of applications. In this paper a novel methodology and instrument is proposed to measure the tactile force between fabric and simulated skin in different directions, and the obtained data are used for assessing fabric frictional property. In this regard, nine groups of woven fabrics consisting of three weave structures and three different weft densities were tested. By fitting the data with a proper equation, the tactile force in terms of fabric direction was predicted. The mentioned equation is also utilized for estimation of frictional behavior of fabric in various directions. Moreover, a single, new parameter called “frictional energy” is defined which has the ability to properly quantify the fabric frictional behavior. Statistical analysis of results reveals that the effect of weave structure and weft density is significant on the fabric friction. Being aware of the effect of fabric construction on friction is a guide for selecting the suitable fabric for various end uses.

Modeling the effect of weave structure and fabric thread density on the barrier effectiveness of woven surgical gowns

Surgical gowns are the shielding cloths worn by the surgical team throughout a surgery to save them from blood pathogens of the patient being operated, and to avoid bacterial infections. Barrier effectiveness of a fabric depends upon the liquid penetration resistance and pathogen resistance of the fabric. The objective of this study was to analyze the effect of different weave structures and fabric thread densities on the barrier effectiveness of the woven surgical gowns. Twelve fabric samples were produced using three different weave structures, i.e. 1/1 plain, 2/2 z-twill, and 3/3 z-twill, and four different fabric constructions and then completed with a water repellent finish. Water repellency spray test and air permeability test were conducted on each of the 12 woven samples. The results of fabric samples were analyzed in Minitab statistical software. The coefficients of determinations (R2 values) of the regression equations show good prediction ability of the developed statistical models. The findings of the study may be helpful in deciding appropriate manufacturing specifications of surgical gowns to attain maximum barrier effectiveness.

Characterization of thermoplastic natural fibre composites made from woven hybrid yarn prepregs with different weave pattern

This paper focuses on the effect of weave structure on mechanical behaviour and moisture absorption of the PLA/hemp woven fabric composites made by compression moulding. The unidirectional woven fabric prepregs were made from PLA (warp) and PLA/hemp wrapped-spun hybrid yarn (weft) with two different weave patterns; 8-harness satin and basket. Unidirectional composites with 30mass% hemp content were fabricated from these prepregs, and compared to winded PLA/hemp hybrid yarn laminates with same composition. The composite from the satin fabric had significantly lowest porosities and best mechanical properties compared to the composite made from the winded hybrid yarn and basket fabric. The tensile, flexural, and impact strength were 88MPa, 113.64MPa, and 24.24kJ/m2, respectively. The effect of weave pattern on water absorption is significant. Although the composite from hybrid yarn laminate has larger water absorption than that of the pure PLA, it exhibits lower moisture absorption than both weaves.

Effect of Weave Structure on Thermo-Physiological Properties of Cotton Fabrics

Abstract This paper aims to investigate the relationship between fabric weave structure and its comfort properties. The two basic weave structures and four derivatives for each selected weave structure were studied. Comfort properties, porosity, air permeability and thermal resistance of all the fabric samples were determined. In our research the 1/1 plain weave structure showed the highest thermal resistance making it suitable for cold climatic conditions. The 2/2 matt weave depicted the lowest thermal resistance which makes it appropriate for hot climatic conditions.

Effect of weave structure on the side-emitting properties of polymer optical fiber jacquard fabrics

Instead of mechanical and chemical treatments, the side-illuminating effect of polymer optical fiber (POF) jacquard fabric was achieved by using the bending of POF in the weave structure. The relationship between side-emitting intensity and bending radius of POF was explored via theoretical derivation, simulation experiments and POF fabric experiments. A theoretical equation was deduced to quantify the correlation between the light emission efficiency and the bending radius of POF based on the bending losses theory in optical fiber. The results of simulation and fabric experiments reached good agreements with the theoretical analysis. In the real fabric structure, the side-emitting intensity was mainly determined both by the bending radius and the float of POF. Significantly, it was just right for designing side-illuminating figure POF jacquard fabric with the effect of a relative degree of lightness or darkness based on the weave and side-emitting intensity database.

CFD analysis on fluid flow through multifilament woven filter cloths

The effects of woven structures on fluid flow through the basic weaves of multifilament woven filter cloths were studied numerically by using the fluid-flow software fluent™. From results of the numerical solution, the flow pattern and the resistance to flow in the interstices were obtained. Results of this work show that the construction of the fabric pores has a significant influence on the flow pattern in the interstices and the downstream. It is also shown that the plain weave gives the highest fluid-flow resistance while the satin weave gives the lowest under the same thread count. Furthermore, in the case of tightly woven filter cloths, the flow is predominantly through the yarns of the cloth; while the flow will generally be directed around the yarns of a loosely woven cloth, especially if the yarns are twisted tightly. A comparison of fluid flow through multifilament woven filter cloth with that of monofilament woven filter cloth is also discussed.
