Summary: This study investigates the weld root fatigue strength of complex structures with severe force concentrations along the weld seam. Fatigue tests were conducted on a pillar assembly with various weld configurations. A comparative analysis was performed using the local nominal weld stress (LNWS), structural weld stress, and effective notch stress (ENS) approaches. The results show that the LNWS approach provides the best prediction, with a scatter range index of 1.26 to 1.68 depending on the weld type. The accuracy of the structural weld stress approach and ENS was significantly lower, with a scatter range index of 4.98 and 5.40, respectively.

Summary: The effects of carbon nanotubes (CNTs) on bitumen's load-induced cracking process were investigated using molecular dynamics (MD) simulation. It was found that CNTs can enhance load transfer efficiency and mechanical performance, elongate the crack propagation path, and increase overall fracture resistance. However, debonding and sliding at the bitumen-CNT interface weakened the interfacial bonding and reduced the strengthening effect. Future research will focus on improving load-transfer efficiency at the interface to fully exploit CNTs' superior mechanical properties.

Summary: This paper presents a polymer/SiO2 hybrid waveguide micro-ring filter based on a short carbon nanotube (CNT) nano-film. The nano-film is coated on the top surface of the polymer waveguide, and both the nano-film and polymer waveguide serve as the core of the device. The nano-film effectively improves the coherent depth and quality factor values of the filter. The filter shows good all-optical tunable performance due to the excellent light absorption characteristic and large thermo-optic effect of the CNT nano-film.

Summary: This study experimentally investigated the monotonic and cyclic properties of CFEP laminate specimens modified with MWCNTs and GNPs, revealing a remarkable synergistic effect of hybrid nanoparticles on the mechanical properties. The addition of hybrid nanoparticles effectively reduced stiffness-based degradation and improved fatigue strength, showing benefits in interlaminar properties and resistance to delamination propagation. The pushout mechanism of MWCNTs and crack deflection effect of GNPs played crucial roles in suppressing microcrack growth and enhancing the resistance to interfacial debonding.

Summary: The synergistic effect of applying hybrid nanoparticles in improving the fatigue property of fiber reinforced polymer composites is studied in this paper. The experimental results show that fiber reinforced polymer composites modified with hybrid nanoparticles under proper nanofiller ratios have higher fatigue strengths. The observation of fracture surfaces reveals that the pullout/bridging effects of carbon nanotubes and the crack deflection effect of graphene nanoplatelets are the main reinforcement mechanisms in enhancing the fatigue strength of the composites.

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.

Summary: The vulnerability of natural fibers to heat and fire poses a significant challenge for their substitution of traditional fiber reinforcements in composite materials. Natural fiber/polymer composites (NFCs) are regarded as potential candidates for engineering applications due to their environmental friendliness and low-impact sourcing. Thus, appropriate approaches need to be implemented to enhance the fire safety of NFCs. This review summarizes and discusses the latest understanding of flammability and thermal properties of natural fibers, with a special focus on their interaction with polymer matrix in fire behavior. Additionally, the latest developments in flame-retardant approaches for NFCs are reviewed, covering both flame retardancy and fire structural integrity. Finally, future prospects and perspectives on fire safety of NFCs are proposed, providing insights into further advancements of NFCs.

Summary: Real-time monitoring of carbon fibre composites during Automated Fibre Placement (AFP) manufacturing remains a challenge for non-destructive evaluation (NDE) techniques. This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
