Summary: In this work, the interlaminar fracture toughness of carbon fiber reinforced epoxy composites has been enhanced by the self-interlocked network arisen from Ti3C2Tx/polyvinyl alcohol aerogel. The results show that the surface-modified MXene effectively improved the mechanical properties of the aerogels. The enhanced fracture toughness can be attributed to cohesive failure at the interface facilitated by stitching-like effect of the aerogel, deflection and twisting of the main crack, and the generation of numerous microcracks.

Summary: Polymer nanoclay composites have significant improvements in mechanical, thermal and barrier properties. However, their effect on dynamic fracture resistance during fast fracture events has not been studied. In this study, the addition of nanoclays to HDPE was found to enhance its rapid crack propagation resistance and improve its properties. The increase in energy consumption and toughening effect of nanoclays prevailed, making it suitable for applications requiring prevention of rapid crack propagation.

Summary: The recent developments in pseudo-ductility have shown that it is possible to make composites safe and suitable for high-performance applications. Repairing damage in composites is a challenging task that can increase their reliability and reduce waste. In this paper, we used polyamide 12 (PA12) films in discontinuous carbon/epoxy - continuous glass/epoxy hybrid composites to improve their toughness and repair delamination damage. The developed repairing method successfully restored the original pseudo-ductile behavior in the tested hybrid laminates. The study presents a detailed design process to facilitate the introduction of reparable pseudo-ductile composites in the industry.

Summary: This study investigates the influence of hybridization on the fatigue limit of bio-composites made of flax, glass/flax, Kevlar/flax, and carbon/flax. The evaluation is done using the critical self-heating temperature and acoustic emission approaches, as well as microscopic characterization for analyzing fracture mechanisms. The results show that hybridization opens new possibilities for controlling the fatigue and fracture properties of composites, and the critical self-heating temperature determined during fatigue tests can serve as an alternative indicator of the fatigue limit of a composite structure, as justified by microscopic examination.

Summary: The article investigates the interlaminar fracture toughness (IFT) of CFRP modified by SWCNT with concentrations of 0.1-0.5 wt%. The addition of SWCNTs negatively affects Mode I IFT, resulting in a decrease of 16-46% depending on the content. However, Mode II IFT testing shows a positive influence of SWCNTs, improving the IFT by up to 35%. The results are analyzed in conjunction with SEM data and previous research, leading to proposed explanations for this behavior.

Summary: A new sustainable approach using a multifunctional devulcanizing agent was proposed for the development of value added devulcanized rubber, which can enhance its application in the tire industry and play a significant role in product quality, production economy, and market competition. By utilizing bis(3-triethoxysilylpropyl)tetrasulfide as the devulcanizing agent, ground tire rubber (GTR) can be mechanochemically devulcanized, allowing for the homogeneous dispersion of silica in the revulcanized rubber compound. The optimal devulcanization time of 40 minutes was determined through swelling experiments and Horikx theory, resulting in better-quality devulcanized rubber and improved mechanical and thermal performance of the revulcanized rubber. Scanning electron microscopy images further confirmed the homogeneous silica dispersion in the rubber matrix. This technology has shown potential for rubber reclamation, contributing to advancements in ecological sustainability.

Summary: Metal-semiconductor nanostructures are widely used in photodetection, photocatalysis, and photovoltaics. In photodetection, the resistance typically decreases with the generation of charge carriers upon illumination, but an opposite response, an increase in resistance, is observed in interconnected metal-semiconductor gratings. This study presents a fabrication method using wrinkle structuring and oblique angle material deposition to create photoresistors with large-area periodic structures and cracks that serve as connections for two-point contact measurements. It is also found that an additional deposition of an amorphous titania layer further enhances the current reduction on photoexcitation.

Summary: Silica and other metal oxides are potential substitutes for carbon black in reinforcing elastomeric materials, offering various additional properties. In this study, the efficacy of in-situ zirconia in enhancing the properties of a rubber blend consisting of natural rubber and nitrile rubber was investigated. The controlled incorporation of in-situ zirconia resulted in improved dispersion, rubber-filler interaction, and crosslinking densities, leading to enhanced thermal stability, flame retardancy, and chemical resistance. The dielectric properties were also improved, especially with surface modification of in-situ zirconia. This study provides valuable insights for the development of high performance elastomeric composites.

Summary: An affordable and promising device called TENG has attracted attention for harvesting energy from mechanical forces. However, its output power is often insufficient for long-term use. In this study, a new fabrication method using 3D printing and transfer printing was proposed to create a hybrid BTO/PDMS film with adjustable piezoceramic layer thickness. The resulting hybrid sensor showed higher charge separation and better impedance matching, leading to improved power density and reproducibility. It also demonstrated high precision in tire wear monitoring and force/pressure sensing.

Summary: This report presents an insightful investigation of the cold crystallization behavior of sulfur-crosslinked polybutadiene elastomers. The influence of crosslink density on the cold crystallization activities of sulfur-crosslinked polybutadiene rubber (BR) is investigated using differential scanning calorimetry, dynamic mechanical analysis, and X-ray techniques. A significant increase in storage modulus (E') is observed at a temperature just above the glass transition temperature (Tg). This behavior was found to be highly dependent on the crosslink density of the rubber. The dynamic mechanical behavior of the sulfur crosslinked BR is supported by further studies using differential scanning calorimetry and low-temperature X-ray diffraction. This study could contribute to a better understanding of the behavior of BR-containing tire tread rubbers at lower temperatures.

A fatigue life model is proposed to predict the S-N curves of the laminates based on energy dissipation approach. The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined. The validity of the proposed model is verified through fatigue tests under different stress ratios and impact energy levels.
