Summary: The study presents a structured fabric with tunable bending modulus made up of three-dimensional particles arranged into layered chain mails. When pressure is applied at their boundaries, the particles interlock and jam the chain mails, resulting in a dramatic increase in bending resistance. This property is due to the high tensile resistance of the interlocking particles, providing potential for lightweight, tunable and adaptive fabrics for various applications.

Summary: The friction between twisted yarns in textile reinforcements during manufacturing is a critical issue that affects the mechanical properties of the preform. This study developed an analytical model based on Hertzian contact theory to describe friction behavior between twisted yarns in orthogonal and non-orthogonal contact. The model considered the contact angle and fiber orientation influenced by twist. Experimental results confirmed the efficacy of the model. The developed model enables characterization of yarn-yarn friction under different conditions, optimizing the textile preform forming process and enhancing mechanical properties of composites.

Summary: Active fabrics are sought after in the development of smart textiles, and liquid crystal elastomers (LCEs) hold promise as the base materials. However, producing suitable LCE filaments for standard textile production methods has been a challenge. This study presents the crafting of active fabrics using LCE yarn woven on a standard loom, allowing control over density and structure. Different weaving patterns were tested, and the twill pattern with stiffer LCE yarn exhibited the greatest blocking force, while the weft rib pattern showed over 10% reversible actuation strain on repeated heating cycles. Circular weaving patterns enabled reversible 3D shape changes in the fabric, creating cone shapes. The seamless combination of active LCE yarns with existing passive yarns could transform the creation of stimuli-responsive textiles.

Summary: Microplastics released from textiles during washing are the most common type of microparticles found globally. Synthetic textile microfibers are released due to mechanical and chemical stresses during washing. A study found that increasing washing load led to a decrease in microfiber release, while decreasing washing load increased released microfibers due to a synergistic effect between water-volume to fabric ratio and mechanical stress.

Summary: This study investigates the impact behavior of water droplets on fabrics of different roughness and coating types. Fabrics with low roughness show lower contact angle and no roll-off, while rougher fabrics have higher contact angles and lower roll-off angles. The restitution of kinetic energy upon rebound is proportional to 1/We, indicating a constant rebound height independent of the impact velocity. Furthermore, the type of coating affects the roll-off angle, the range of Weber numbers for rebound, and to some extent, the restitution coefficient.

Summary: The development of wearable technology has led to the research of new power supply sources for battery-less wearable devices. Wearable thermoelectric generators (wTEGs) can generate energy from the temperature difference between the human body and the surrounding environment. Coating textiles with conductive polymers through electrodeposition on fabrics coated with multi-walled carbon nanotubes (MWCNT) has been developed in this study. The results show that fabrics coated with polyaniline: sulfuric acid (PANI:H2SO4) have low thermal stability and unsuitable electrical conductivity under wearable stress, while fabrics coated with poly (3,4-ethylenedioxythiophene: perchlorate) (PEDOT:ClO4) and polypyrrole: perchlorate (PPy:ClO4) exhibit good thermal stability and positive evolution of electrical conductivity, demonstrating their potential use in practical wearable applications.

Summary: Nowadays, components made of unidirectional composite materials are widely used in various engineering fields. However, the low out-of-plane properties of these materials make them susceptible to impulsive loads, such as impact events. Therefore, it is crucial to continuously assess the condition of structures and determine if damage has occurred. This study proposes a baseline-free methodology for determining the coordinates of high-velocity impacts on complex structures and evaluates the occurrence of damage during the impact. Experimental tests on carbon fibre reinforced polymers with embedded sensors demonstrate the effectiveness and reliability of the proposed method in accurately estimating impact localization and evaluating structural integrity.

Summary: This study proposes a novel baseline-free method for real-time structural damage diagnosis during low-and high-velocity impact by decomposing the propagating modes caused by impact events. The high-frequency and medium-low frequency components are separated using Hilbert-Huang Transform (HHT) to obtain amplitude and phase of two propagation modes. The Energy Ratio Xi, defined as the ratio between maximum instant energy of the extensional mode and flexural mode, is proposed as an indicator of damage probability. Experimental results on aluminium and CFRP samples demonstrate the effectiveness of the proposed method in discerning elastic and damaging impacts.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.
