Summary: The demand for high thermal conductivity has led to the development of materials that can efficiently manipulate thermal energy. Polymer-based composites on hexagonal boron nitride (h-BN) are effective for providing thermally conductive and electrically insulating pathways, but it is difficult to establish strong interfacial connections within polymer chains using BN alone. In this study, hydroxylation of h-BN and carbon nanotubes (CNT) was achieved, followed by the formation of a urethane crosslink between the filler-filler interfaces and thermoplastic polyurethane (TPU) matrix. This unique hybrid structure achieved an unprecedented thermal conductivity of 4.52 Wm-1K-1 at just 60 wt% loading of h-BN and 2 wt% of CNT, as well as outstanding yielding strength and Young's modulus by tension.

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.
