Conventionally laminated spacer composites are extensively applied in many fields owing to their light weight. However, their impact resistance, interlaminar strength, and integrity are poor. In order to overcome these flaws, the zigzag-shaped 3D woven spacer composites were rationally designed. The zigzag-shaped 3D woven spacer fabrics with the basalt fiber filaments tows 400 tex (metric count of yarn) used as warp and weft yarns were fabricated on a common loom with low-cost processing. The zigzag-shaped 3D woven spacer composites were obtained using the VARTM (vacuum-assisted resin transfer molding) process. The three-point bending deformation and effects of damage in zigzag-shaped 3D woven spacer composites were studied both in experiment and using the finite element method (FEM). The bending properties of zigzag-shaped 3D woven spacer composites with different direction, different numbers of weaving cycle, and different heights were tested in experiments. In FEM simulation, the geometrical model was established to analyze the deformation and damage based on the 3D woven composite structure. Compared with data obtained from the experiments and FEM simulation, the results show good agreement and also prove the validity of the model. Based on the FEM results, the deformation, damage, and propagation of stress obtained from the model are very helpful in analyzing the failure mechanism of zigzag-shaped 3D woven composites. Furthermore, the results can significantly guide the fabrication process of real composite materials.

This study presents an experimental investigation on the low-velocity impact response of three-dimensional integrated woven spacer sandwich composites made of high-performance glass fiber reinforced fabric and epoxy resin. 3D integrated woven spacer sandwich composites with five different specifications were produced using a hand lay-up process and tested under low-velocity impact with energies of 5 J, 10 J, and 15 J. The results revealed that the core pile’s heights and diverse impact energies significantly affect the stiffness and energy absorption capacity. There is no significant influence of face sheet thickness on impact response. Moreover, the damage morphologies of 3D integrated woven spacer sandwich composites under different impact energies were analyzed by simple visualization of the specimen. Different damage and failure mechanisms were observed, including barely visible damage, visible damage, and clearly visible damage. Moreover, it was noticed that the damage of 3D integrated woven spacer sandwich composites samples only constraints to the impacted area and does not affect the integrity of the samples.

The research is focused on the design and development of woven textile-based structural hollow composites. E-Glass and high tenacity polyester multifilament yarns were used to produce various woven constructions. Yarn produced from cotton shoddy (fibers extracted from waste textiles) was used to develop hybrid preforms. In this study, unidirectional (UD), two-dimensional (2D), and three-dimensional (3D) fabric preforms were designed and developed. Further, 3D woven spacer fabric preforms with single-layer woven cross-links having four different geometrical shapes were produced. The performance of the woven cross-linked spacer structure was compared with the sandwich structure connected with the core pile yarns (SPY). Furthermore, three different types of cotton shoddy yarn-based fabric structures were developed. The first is unidirectional (UD), the second is 2D all-waste cotton fabric, and the third is a 2D hybrid fabric with waste cotton yarn in the warp and glass multifilament yarn in the weft. The UD, 2D, and 3D woven fabric-reinforced composites were produced using the vacuum-assisted resin infusion technique. The spacer woven structures were converted to composites by inserting wooden blocks with an appropriate size and wrapped with a Teflon sheet into the hollow space before resin application. A vacuum-assisted resin infusion technique was used to produce spacer woven composites. While changing the reinforcement from chopped fibers to 3D fabric, its modulus and ductility increase substantially. It was established that the number of crossover points in the weave structures offered excellent association with the impact energy absorption and formability behavior, which are important for many applications including automobiles, wind energy, marine and aerospace. Mechanical characterization of honeycomb composites with different cell sizes, opening angles and wall lengths revealed that the specific compression energy is higher for regular honeycomb structures with smaller cell sizes and a higher number of layers, keeping constant thickness.

Three-dimensional (3D) woven spacer composites are competitive materials in aerospace fields due to their excellent integrated, light-weight structure. The face sheets of the 3D woven spacer composites are crucial for the mechanical properties. In this study, 3D hybrid composites, which are composed of glass and carbon fibers in the face sheets and glass fiber in the core layer as reinforcement and epoxy resin as the matrix, were designed and fabricated. The bending test results show that with the increase of the carbon fibers in the face sheets, the normalized bending strength of hybrid spacer composites showed limited improvement, while their normalized bending moduli and bending stiffnesses were significantly improved. The optical and scanning electron microscope images of the fractured surfaces reveal that the fibers in the top face sheet, which is under compression by the indenter, are damaged first and cause the failure of the entire structure, whereas the fibers in the bottom face sheets are stretched during the bending test and slightly damaged. In addition, in the failure cross-sections, pull-out of the carbon fibers is observed due to its limited interfacial bonding with the epoxy resin. This work could help optimize 3D hybrid woven spacer composite structures for better performance and lower cost.

This paper undertakes to study the flexural behavior of 3D integrated weft-knitted spacer composites, under three-point bending. The integrated-knitted spacer fabrics were produced with various cross-sectional shapes on a computerized flat-knitting machine utilizing electrical grade glass (E-glass) fibers. The sandwich composites were manufactured by vacuum-assisted resin transfer molding using unsaturated polyester resin. Continuing the process, hand lay-up method was used to reinforce the face sheets of fabricated sandwich structure with glass woven fabrics. Bending performance of the produced composites was compared with polyurethane foam core sandwich composites. The results revealed that the cross-sectional shape has significant effect on the bending performance of the 3D integrated weft-knitted spacer composites. Also, the spacer reinforced composite with V-shape cross-section has the highest bending stiffness than composites with U-shape cross-section as well as polyurethane foam core sandwich composite. The failure modes of 3D integrated weft-knitted spacer composites include: core shear failure, compression failure of upper face sheet and tensile failure of lower face sheet.

Three-dimensional (3D) woven spacer composites have the advantage of being lightweight and strong for use in various segments of structural engineering and automobiles due to their superior mechanical properties than conventional counterparts. In this investigation, the influence of different cell geometries of 3D woven spacer fabrics, namely rectangular, triangular and trapezoidal with woven cross-links, upon their mechanical behaviors, especially compression energy, was studied through FEM (finite element method). Cell geometries were changed into different heights and widths and evaluated through simulation and experiments. Simulation of the structure was carried out by the Abaqus platform, and validation of the results was done for the rectangular structure. It was found that compression energy increases with an increment in width, while initially, it shows the tendency to increase and subsequently decrease with an increment in height for the rectangular structure. Compression energy increases with an increase in the angle of the triangular structure; however, it shows the opposite trend in the case of the trapezoidal structure. The outcome of the result shows good agreement between simulation and experimentation values of more than 94% accuracy.

Three-dimensional integrated woven spacer sandwich composites have been widely used as industrial textiles for many applications due to their superior physical and mechanical properties. In this research, 3D integrated woven spacer sandwich composites of five different specifications were produced, and the mechanical properties and performance were investigated under different load conditions. XR-CT (X-ray computed tomography) images were employed to visualize the microstructural details and analyze the fracture morphologies of fractured specimens under different load conditions. In addition, the effects of warp and weft direction, face sheet thickness, and core pile height on the mechanical properties and performance of the composite materials were analyzed. This investigation can provide significant guidance to help determine the structure of composite materials and design new products according to the required mechanical properties.

In this paper, four commonly used car seat covers, made from leather as well as from woven, knitted and 3D spacer fabrics are tested as sandwiched and separate layers to determine the effect of the lamination and layers on air and water vapor permeability. Different combinations of interlining materials are also tested to obtain the optimum comfortable car seat cover. This analysis gives us a real idea of which layer negatively affects the breathability of the car seat. The focus of this part of research was to identify the issues within the car seat material instead of factors like external cooling or the clothing of the driver. It was observed that the polyurethane (PU) foam and lamination significantly reduce the permeability of the car seats. The 3D spacer fabric shows the best top layer properties as compared to classical woven, leather or knitted car seat covers. The research shows how layers and lamination cause thermo-physiological discomfort of car seats.

The need for innovative lightweight materials are rapidly increased in the recent years, owing to their cost-effective, high-strength, environmentally-sound use of materials and process technologies, in addition to that they reduce the weight of a product. The characteristics of 3D-spacer fabrics as one of the most important lightweight materials in future are multifaceted not only owing to its extremely light materials, but also because of exceptionally high stiffness to weight ratio compared to other constructions. It is also one possible method for improving the properties of fabric-reinforced composites. It can enhance the through-the-thickness properties, such as shear strength, dimensional stability, damage, tolerance, and fracture toughness that are critical for many structural applications. Spacer fabric has been employed in high-technology applications because of its critical mechanical properties related to high tensile strength, tear strength and stiffness. Furthermore, its multidirectional structures allow with more reinforcement along the thickness direction leading to an increase in stiffness and strength properties. The fundamental aim of this thesis exists in the development of a new kind of woven spacer fabrics for the light weight composites materials, in an effort to weave spacer fabrics that can not be realized with the old technology which are mentioned above. Therefore, the work in brief focuses on two main goals: 1. Development of a new kind of spacer fabrics for composites in the lightweight constructions. 2. Development of special devices of a narrow weaving machine for standing the process of the new kind of spacer fabrics production. The slippage strength test had to be carried out for the floated warp yarns through the ground fabrics by using different elements of woven fabric structures variables represented in different fabric constructions, different weft densities and different repeats of constructions by using different materials. The importance of this test related to the backward-movement of the floated warp yarns which is the crucial stage in the weaving process of spacer fabrics during the backward-movement. The results of this test determine the required forces for the backward-movement, on the other side it is the best method to observe the behavior of structure elements during the backward movement. The results of the slippage strength had been statistically analyzed, and the weaving process for the spacer fabrics had been achieved. It was concluded that the best properties for the woven spacer fabrics and the optimum case for the weaving process on the test weaving machine had been achieved when the following items are realized: Development of the narrow weaving machine is closed in assisting operations, let-off and take-up and enhancement for take-up processes. Extra let-off and take-up devices must be constructed at the weaving machine. Extra let-off device has to be used for controlling the floated warp yarns of ground fabrics. On the other side, extra take-up and the developed take-up devices have to be used for controlling the woven spacer fabrics. The experimental results give fundamental knowledges for the next steps in research and development of woven spacer fabrics made of high-performance yarns on the wide weaving machineDie Ziele der Arbeit bestanden in der Entwicklung der Geometrie der Spacer Fabrics und der notwendigen Falteneinrichtung an der Bandwebmaschine. Spacer Fabrics werden ausschließlich aus zwei Deckflächen, die durch eingewebte Stege verbunden sind, gefertigt. Zur Entwicklung der Spacer Fabrics muss eine Doppelnadel-Bandwebmaschine mit zwei Webfächern eingesetzt werden. Für die Faltenwebeinrichtung werden der entwickelte Extra-Kettablass und der Extra-Abzug benötigt. Der Antrieb und die Steuerung des Extra-Abzuges erfolgen durch einen Synchronantrieb und der Antrieb und die Steuerung des Extra-Ablasses durch Pneumatik.Eine frei programmierbare Steuerung der Faltenwebeinrichtung ermöglicht eine sichere und optimierte Synchronisation zwischen Webprozess und Faltenbildung. Im Ergebnis einer systematischen Strukturentwicklung von Spacer Fabrics und der Simulation ihrer günstigen Herstellung mittles eines speziell entwickelten Slippage Strength Tests werden die optimalen Strukturen ermittelt. Die experimentellen Untersuchungen bringen grundlegende Erkenntnisse für die folgenden Forschungsschritte zur Entwicklung von gewebten Spacer Fabrics mit Hochleistungsgarnen auf Doppelgreiferwebmaschinen

Woven fabrics consist of at least two sets of yarns (warp and weft) that are interlaced at right angles to each other. The woven structures that only contain two systems of yarns are called simple woven fabrics, while those that include at least 3 systems are considered compound structures. There are many structural variants of compound woven fabrics (double/triple/multiple compact structures, spacer fabrics etc.). The structural characteristics of each structure induce specific properties that enable them to be used in art and design applications, but also in industries such as engineering, aerospace, automotive, biomedical, leisure etc. Compound woven fabrics (principally produced by the multiple-warp weaving method) have long been used for the manufacturing of double and triple cloths for bags, webbings and carpets. Nowadays, due to superior mechanical properties, the use of compound woven fabrics as technical textiles and especially as a reinforcing medium for composites is becoming a popular choice. As a result, some of the CAD producers which were, until recently, mainly oriented towards developing software applications for simple woven fabric design, started to pay more attention to this subject offering performing software solutions for the design of compound woven structure. This paper presents the main CAD solutions available on the market in this field (TexGen, WiseTex, ScotWeave, 3D Weave) and focuses on the TexM software, a learning-oriented solution for compound woven fabrics design, created by researchers from Faculty of Textile-Leather and Industrial Management of Iasi, Romania. In comparison to the other aforementioned software, TexM makes use of a sectioning method to obtain a graphic representation of the weave structure in each layer. TexM is now used for some time and the excellent results of the students confirm the usefulness of this kind of educational software in understanding the structure of compound woven fabric.

Every economic studies and OEM surveys show that communications and high-speed computing are the fastest growing electronics applications. The old rules for making these electronic devices are being broken such that whenever possible, space and weight are being saved, while still maintaining reliability and cost of the system. The consumer mobile phone exemplifies this technology trend. Many models are now equipped with personal organizers, multimedia, and wireless communications capabilities. To achieve these, there is much interest in homogeneous materials systems to improve mechanical and electrical performance from the semiconductor packaging to the assembled devices. System-on-chips (SOC), system-on-package (SOP), and rigid-bend-to-fit (3D) packaging are examples of the technologies being explored to get the most performance per space. Aramid substrates are used in 100% PWB and HDI microvia stack-ups in IC packaging, handheld devices, high-end computing, backplanes, and military/ avionics, while providing reliability and reduced overall costs. The talk will focus on why non-woven aramid substrates as homogeneous materials systems improve mechanical and electrical performance from the semiconductor packaging to the assembled devices. We will share data showing the versatility and applicability of aramid non-woven reinforced substrates impregnated with various resins, including why and how non-woven aramid substrates are laser ablateable; are able to be made thin and handleable, lightweight and bendable, thermally and dimensionally stable; and has low CTE able to be used in 100% PWB and HDI microvia stack-ups in IC packaging, handheld devices, high-end computing, backplanes, and military/ avionics, while providing reliability and reduced overall costs.

Abstract Men and women with lower limb amputations struggle with managing the balance between prosthesis alignment and shoe heel rise. A novel prosthetic ankle-feet system is being developed to support a wider range of footwear options for men and women with lower limb amputations. Each rigid foot is customized to fit the footwear of choice and can be rapidly attached to (or released from) an ankle unit which remains attached to the prosthesis. The ankle unit has a mass of 318g and is small enough to fit in the design volume of a 22cm foot across a range of heel rises. The ankle uses elastomeric bumpers arranged in a wiper design to maximize space efficiency. Structural testing has shown that the 3D printed custom Nylon 12 feet withstood 4584N of forefoot loading without failure based on the ISO 10328 loading parameters, indicating suitable strength to support safe human use in the laboratory. The feet have a mass of 446g. Feedback from two women Veterans with lower limb amputations reinforced the importance of improving access to shoes with different heel rises. Future activities will include cyclic fatigue testing, additional weight reduction, and incorporating suggested design refinements.

Utilizing the negative thermal expansion property of ZrW2O8, Perspirable skin, an autonomous cooling system, was designed for externally heated surfaces of reentry vehicles such as Space Shuttle. In this material system, several ZrW2O8 pegs are shrink-fit into the Reinforced Carbon-Carbon composite (RCC) skin. At working conditions, a gap or interference forms between the two materials and the compressed gas within the vehicle can blow out through the gap. The atmospheric air, rather than contributing to the frictional heat between air and skin, is mixed with the cold compressed air over the surface. Due to the nonlinear thermoelastic properties within the operating temperatures, Finite Element Analysis was used to design the geometry of the ZrW2O8 pegs and the best fiber arrangement of the RCC for this material system. The geometry of the peg with a larger radius at the top surface and a smaller radius at the bottom part ensures the secure contact of two materials at the working condition. The design with the frustum of a cone shaped top offered a better and shorter route for the coolant gas to be passed. The best type of RCC is found to be 3D woven orthogonal.

Breast cancer has a high mortality rate and caused about 13.7% of all cancer types deaths in women. Mammography imaging, having a good sensitivity to cancer, is used along with biopsy in a routinely manner, to differentiate between malignant and benign masses. Biopsy is an invasive procedure, and to reduce the necessity for performing it, ultrasound elastography was proposed. Elastography is a potential imaging technique to characterize breast masses, and to differentiate malignant from benign lesions, based on imaging estimated tissue strains under compression. This can result in lowering the number of unnecessary biopsies. Using 3D elastography, lesion relative stiffness with the surrounding soft tissue is estimated at different compression levels, and used as a classification parameter to judge the malignancy of the lesion. In addition, elastography provided a means of emphasizing the strain difference of the lesion from the surrounding soft tissue, which can be used as an additional classification parameter. A pilot study on volunteered patients was performed, and results were compared with biopsy diagnosis as a reference. Initial elastography results showed good agreement with biopsy outcomes. Moreover, we constructed different strain elastograms including first principal, maximum shear and von Mises strains. Those new types of elastographic volumes incorporated the normal axial and shear strains together, which provided better distinction of the hard lesion from the soft tissue. In summary, the proposed elastographic techniques can be used as a noninvasive quantitative characterization tool for breast cancer, with the capability of visualizing and separating the masses in three dimensional space.

Introduction: Abbreviated MRI protocols have been proposed to reduce examination time, patient discomfort, and costs for breast cancer screening. However, an abbreviated MRI protocol for assessing neoadjuvant chemotherapy in breast cancer is yet to be explored. Objective: We sought to develop an abbreviated MRI protocol to evaluate the response to neoadjuvant chemotherapy treatment for invasive breast cancer carcinoma with diagnostic performance equivalent to that of the full protocol. Methods: This was a retrospective, single-center, cross-sectional study. This study comprised 210 women diagnosed with invasive breast carcinoma of no special type who underwent breast MRI after neoadjuvant chemotherapy between 2016 and 2020 in Curitiba, PR, Brazil. Breast MRI scans were reevaluated, first with access only to axial 3D SPAIR without contrast and first post-contrast time (two sequences); next to the second post-contrast time (three sequences); then to the third post-contrast time (four sequences); and finally, to the full protocol (seven sequences). The diagnostic performance (sensitivity, specificity, positive predictive value, negative predictive value, and accuracy) of the three abbreviated protocols and the full protocol was analyzed using the Wilcoxon nonparametric test. Results: The median age of the study population was 47 years. The diagnostic performance of abbreviated protocols with three and four sequences and the full protocol was identical. The two-sequence abbreviated protocol showed higher specificity (84.6%), but a higher probability of false negatives (16.8%) and a lower sensitivity (83.2%) than the other protocols, which showed values of 81.3, 8.4, and 91.6%, respectively. The abbreviated protocol with three sequences showed an average underestimation of only 0.03 cm in the measurement of the longest axis of the residual lesion (p=0.008), but an average reduction in acquisition time of 75%. Conclusion: The three-sequence abbreviated MRI protocol showed diagnostic performance equivalent to the full protocol but with a 75% reduction in acquisition time.
