Summary: Studies have shown that the fraction of the secondary filler inducing the maximum synergistic effect decreases with increasing total filler content, leading to an anti-synergistic effect at high fractions. Effective phonon transfer and high thermal conductivity can be achieved at the optimum fraction due to improved filler network formation. The Kim-Jang-Lee model was proposed for both the synergistic and anti-synergistic effects based on the ratio of fillers in the composites.

Summary: This study aims to obtain a sustainable nanocomposite by incorporating graphene nanoplatelets (GNP) into a bio-based polyamide 11 and biodegradable poly (lactic acid) blend matrix. The results show that the inclusion of GNP increases the crystallinity of polyamide 11 and the thermal degradation temperature of poly (lactic acid), while enhancing the storage modulus and glass transition temperature of the matrix. However, a high amount of GNP leads to a decrease in the tensile strength of the matrix.

The displacement of the core and shell of the fibers had significant effects on the characterization, antibacterial properties, and cytotoxicity of the bicomponent fibers. The bicomponent nanofibers with PLA-Ag NPs in the core were thinner, while those with PLA-Ag NPs in the shell were more hydrophobic.

Summary: Although petroleum-based polymers have a lengthy decomposition process, they are still widely used. However, due to environmental pollution concerns, there is growing interest in biodegradable polymers. Poly(lactic acid) (PLA) is a biopolymer with similar performance to traditional polymers, but its poor properties limit its application. This study aimed to expand the usage of PLA by improving its properties through the addition of graphene nanoplatelets (GnP) and/or Joncryl (R) to carbon fiber (CF) reinforced PLA composites. Tensile tests, adhesive wear tests, DSC, TGA, and SEM analyses were conducted to investigate the effects of CF, GnP, and Joncryl (R) addition to PLA. The composite composition with simultaneous addition of 10 wt.% CF, 0.5 wt.% GnP, and 2 wt.% Joncryl (R) showed the best performance in all tests and analyses.

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.

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.
