Summary: We investigated the liquid crystal phase behaviors of sodium cholate-stabilized single-walled carbon nanotube (SWCNT) aqueous dispersions with different SWCNT aspect ratios. The isotropic-to-nematic phase transition occurs at a lower concentration for the SWCNT dispersion with a larger aspect ratio, as expected by the Onsager theory. A well-aligned film was successfully fabricated from the dispersion with a higher SWCNT aspect ratio using simple blade coating. We also prepared SWCNT dispersions with different surfactants, sodium deoxycholate, and sodium taurodeoxycholate, to change the surface condition of SWCNTs, which may affect the LC transition concentrations.

Summary: Barium ferrite (BaFe12O19) is a potential microwave absorption material, but the performance is limited by the poor dispersion of carbon nanotubes (CNTs) in the composites prepared by ball-milling method. In this study, CNTs were uniformly introduced into the precursor of BaFe12O19 during the auto-ignition process and calcined under different atmospheres. The resulting CNT/BaFe12O19 composites exhibited significantly improved microwave absorption performance compared to pure BaFe12O19 and CNT/BaFe12O19 composites prepared by ball-milling method.

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: 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.
