Summary: The challenge of incorporating carbon fiber and thermoplastic resin in wind turbine rotor-blades lies in their behavior during lightning events. A comparative study using lightning and dielectric strength tests was conducted, revealing that the behavior of the resins was similar. The integration of earth terminals in carbon fiber laminates was crucial for proper lightning discharge, and the fiber-to-fiber and fiber-to-terminal contact affected the electrical resistance of the laminates.

Summary: A novel continuous NiTi Shape Memory Alloy Fiber Reinforced (SMAFR) B2-FeAl based metal-intermetallic laminate (MIL) composite was prepared and characterized. The composite exhibited a multi-layer structure comprising a stainless steel layer, an intermetallic layer, and an intermediate transition layer. The SMAFR MIL composite demonstrated superior mechanical properties compared to the MIL composite without NiTi fibers, attributed to the high tensile properties of NiTi fiber, the good interfacial bonding, strong interfacial reaction products, and pullout effect of NiTi fibers.

Summary: The sensitivity of buckling behavior in structures to imperfections, particularly fiber misalignments in composite structures, is addressed in this paper using random field analysis. By quantifying the effects of misalignments and making small changes to the local fiber orientation, the structure's performance can be improved and its robustness to misalignments increased. Stochastic analyses show an overall increase in buckling load and a reduction in variability, demonstrating the effectiveness of the approach in enhancing structural performance.

Summary: In a fiber optic gyroscope rotational inertial navigation system, attitude errors may change due to the change of misalignment angles. It is difficult to calibrate different kinds of misalignment angles using traditional methods. Therefore, a calibration method based on fine alignment algorithm is proposed. The accuracy of this method is proven through simulations and experiments, and it has been found that this method can significantly reduce position errors.

Summary: The study focuses on the relationship between electric properties and structural features in newly designed laminated Al/Cu conductors manufactured through rotary swaging and subjected to two post-process heat treatments. Structural analysis was conducted using scanning and transmission electron microscopy, mechanical properties were investigated through microhardness measurements, and both experimental examination and numerical simulation were used to analyze the electric properties during direct and alternating current transfers. The fabrication of the laminate via rotary swaging resulted in advantageous combinations of electric and mechanical properties, and the laminate design effectively reduced power losses during alternating current transfer. The specific electric resistivity was mainly affected by structural features, such as grain size, grain boundaries and twinning, and texture orientations and intensity. The lowest specific electric resistivity (22.7 omega mx10-9) was observed in the swaged laminate heat treated at 350 degrees C with structure restoration. Annealing at 250 degrees C partially restored the structure, resulting in a bimodal grain size distribution and significant deterioration of the electric properties.

Summary: This paper identifies a phenomenon of "feigned death" induced by partial delithiation in silicon composite electrodes, which can be completely recovered by providing a reboot with full delithiation, confirming the integrity of the electrode. The feigned death is caused by asymmetric phase transformation between crystalline and amorphous phases in silicon electrodes, triggered by a high depth of lithiation generating the c-Li3.75Si phase but a low depth of delithiation not eliminating the crystalline phase.

Summary: The influence of contact loss at the interface on the stress and stress gradient in the active particle during delithiation and relaxation is significant, affecting the mechanical-chemical coupling. In the later stage of delithiation, stress is mainly affected by incomplete interfacial constraint, while the effect of concentration gradient becomes negligible.

Summary: This study investigates the impacts of irregular electrode shape on lithiation performance. It finds that uneven lithiation and edge effects occur in square electrodes, leading to poorer cyclic performance. Numerical simulations reveal that strong electric fields near the electrode edges result in highly inhomogeneous lithium flux, causing fast lithiation saturation and dendrite growth. The same edge effects are also observed in face-to-face electrodes, leading to a fake lithiation saturation phenomenon. Strategies to minimize edge effects, such as reducing electrode sharp tips, are suggested to improve electrochemical performance.

Summary: This study optimized an in situ method for measuring the mechanical behavior and properties of silicon-based electrodes during electrochemical cycling. The research found that the swell strain and partial molar volume of Si electrodes increase with the Li concentration, while the elastic modulus generally decreases. The in-plain stress transforms from tensile stress to compressive stress during lithiation and shows an increasing tendency, but reverses during delithiation. These findings provide input parameters for battery modeling and help understand capacity fading of Si electrodes.

Summary: This paper investigates the tool-ply friction behavior of jute/PLA biocomposites in thermoforming. A pull-through friction testing device was developed to characterize the tool-ply friction behavior of jute/PLA prepreg at elevated temperature. The effects of alkali treatment, fiber orientation, normal force, and slipping velocity were studied, and a quantitative definition of tool-ply friction behavior was achieved. The results indicate a strong relationship between tool-ply friction behavior and woven and fiber structures, indicating hydrodynamic lubrication.

Summary: Micro-arc oxidation (MAO) treatment was used to modify aluminum (Al) alloys in order to improve bond strength with carbon fiber reinforced polymer (CFRP). The treatment successfully created a porous surface with better hardness, roughness, and wetting, and introduced resin pre-coating (RPC) and carbon nanotube (CNT) fiber bridging to improve the bonding interface. The combined treatments significantly increased the bond strength by up to 156.1%, indicating the feasibility of MAO as an alternative method for manufacturing high-performance Al-CFRP composites in industrial production.

Summary: Faster heating rates and higher process temperatures can reduce the total process time while achieving the same degree-of-cure. Thermal analysis shows that thermoplastic interleaf particles melt at the recommended curing temperature. A short dwell at a lower temperature can prevent the mixing of thermoplastic particles and thermoset pre-polymer.
