Summary: This study investigated the low-velocity impact and interfacial bonding properties of weft-knitted ultra-high-molecular-weight-polyethylene (UHMWPE) filaments reinforced epoxy resin and vinyl ester resin composites. It was revealed that the composites with interlock air space stitch reinforcement exhibited the highest mechanical properties and puncture resistance. The tensile and flexural properties of the epoxy matrix composites were better than vinyl ester matrix composites, but their low-velocity impact resistance was slightly inferior. The interfacial bonding ability between vinyl ester resin and weft knitting structure reinforcement was stronger.

Summary: This paper investigated the degradation of sisal fiber in ultra-high performance concrete (UHPC) under steam curing or standard curing conditions, and studied the interfacial bonding between sisal fiber and UHPC. The results showed that the bonding between sisal fiber and matrix under steam curing conditions was lower than that under standard curing conditions, which was caused by the thermal contraction of sisal fiber at high temperatures. The experimental results also revealed that the degradation of sisal fiber in UHPC was limited during the curing period and the long-term performance should be further studied.

Summary: This study investigated the effects of three different treatments on abaca fibers, including hornification, 3% NaOH concentration solution, and a coating of silica fume with natural latex into cementitious composites. The fibers were characterized before and after the treatments using SEM, XRD, FT-IR, TGA, and tensile tests to analyze structural and chemical changes. The setting time and flexural strength of the cementitious composites (at 7, 14, and 28 days) were analyzed to determine the optimal treatment, dosage, and length. It was found that the hornification treatment with a length of 30 mm and a dosage of 0.2% showed a flexural strength of 8.2 MPa.

Summary: The impact-induced bonding can be a foundation for rapid solid-state additive manufacturing. However, the mechanisms behind this bonding process are not well understood due to the complexity caused by the transient process and extreme loading conditions. In this study, a novel impact-induced bonding process of copper flakes is reported, which has the advantages of longer duration, macroscopic length, and low ambient temperature. Finite element simulation and microstructure characterization reveal that the bonding strength can reach the strength of bulk material, and the embedding between microstructures and the recrystallization of grains are significant factors for impact-induced bonding.

Summary: A new method called nano-scale electrochemical sculpture (NES) has been developed to enhance the bonding strength of fiber metal laminates (FMLs-NES). Through systematic investigation and comparison with traditional surface treatments, it has been found that FMLs-NES exhibits the smallest damage area and energy absorption, while maintaining structural integrity after impact. Finite element simulations have also provided insights into the impact damage progression and failure mechanisms, and the validated finite element model can be used to optimize the stacking sequence and predict residual strength after impact.

Summary: Ultra-high molecular weight polyethylene (UHMWPE) composites are commonly used in protective armor systems, and the design of such systems has traditionally relied on empirical studies, which can be costly and time consuming. A multi-scale, finite element-based representative volume element (RVE) approach has been developed to capture the ply-level material nonlinearity and strain-induced fiber reorientation of UHMWPE composites subjected to low-velocity impact (LVI) loading. This approach accurately predicts the impact performance of UHMWPE composite materials and can be used to evaluate various laminate architectures and processing conditions.

Summary: Fiber-reinforced rubber composites (FRRC) are widely used, but the traditional dipping method using resorcinol-formaldehyde-latex (RFL) poses health and environmental risks. In this study, a new dipping system based on low-toxic and low-volatile resin was developed to achieve equivalent interfacial adhesion. By optimizing the phloroglucinol/terephthalaldehyde (P/T) ratio, a uniform dipping layer with suitable pick-up was achieved, resulting in strengthened interfacial adhesion.

Summary: Among natural fibers, basalt fibers have recently emerged as the main candidate to replace glass fibers in composite materials. The aim is to optimize the load transfer efficiency between the two different phases in the composite by growing carbon nanostructures on the surface of unsized basalt fibers using less common catalysts. By lowering the synthesis temperature, the intrinsic properties of the basalt fibers were preserved and dense and uniform carbon nanostructures were obtained. These less common catalysts provide an expanded design strategy for obtaining composites with improved interfacial bonding and multifunctional properties.

Summary: In this study, the transport of ions through graphene nanopores driven by concentration gradients is investigated using molecular dynamics simulations. The diffusion coefficients of K+ and Cl- are calculated for various pore sizes and porosities. The results show that the diffusion coefficient is sensitive to the pore size when the diameter is smaller than 3 nm, while it remains largely independent for relatively large pores. The dependence of the diffusion coefficient on porosity exhibits a near-linear relationship. The findings provide useful information for the design and fabrication of nanoporous structures for ion transport.

Summary: This letter examines the performance of on-silicon inductor coils with integrated buck dc-dc converters made using a 180 nm CMOS process. A parallel shunting structure with different metal layers was chosen for its lower resistance and higher inductance in low-power IoT scenarios. Simulation results demonstrate stable values of more than 230 nH for the fabricated inductors within the expected frequency range. The proposed dc-dc converter achieves an efficiency of 69.1% at 30 MHz for a 12.9 mA load, operating at voltage levels of 2.4 to 1.2 V. Our approach enables high-inductance integration without the need for costly postprocessing techniques, expanding the application of power inductor and dc-dc converter integration.

Summary: We introduce novel zone-based hybrid laminate concepts to enhance the high-velocity impact (HVI) response of baseline carbon fibre-reinforced polymer (CFRP) composites. By keeping approximately 80% of the baseline CFRP mass in the hybrid concepts, similar areal weights and substantial in-plane mechanical properties are maintained. Three zones are identified along the laminate thickness, and tailored materials are incorporated to improve the HVI response. Various materials, including carbon (thin- and thick-plies), glass, Zylon, ultra-high molecular weight polyethylene (UHMWPE), shape memory alloy/carbon fabric, and ceramic, alumina, and titanium sheets, are studied. All laminate concepts have comparable areal weights for meaningful comparison. Experimental results demonstrate up to 95% improvement in energy dissipation compared to the baseline quasi-isotropic (QI) CFRP configuration.

The diffusion coefficients of water, Li+, and Cl- were calculated in 3D-NGSs with different LiCl concentrations, porosities, and surface charge densities. The results showed that the diffusion coefficients followed the Arrhenius Equation and power laws for the dependence on temperature and porosity, respectively. They decreased with increasing salt concentration.
