Summary: This study focuses on the functionalization and distribution of conductive fillers, as well as the interfacial compatibilization of polymer blends, in order to improve the electrical conductivity and electromagnetic interference shielding efficiency of composites. By modifying the carbon nanotubes (CNTs) with an ionic liquid copolymer and controlling the blending process, selective localization of CNTs at the interphase and the formation of effective conductive networks at the interface were achieved. This resulted in a significant increase in electrical conductivity and a maximum EMI shielding efficiency of 41 dB for the PLA/PCL/PIL/CNT composites.

Summary: The shape and particle size of the filler play a crucial role in determining the performance of composite materials. In this study, the effects of boron nitride (BN) shapes and sizes on the rheological properties, thermal conductivity, and passive cooling of polyethylene composites were investigated. Large-sized fillers negatively influenced the formation of a rheological network in the composites, but positively affected the thermal conductivity with a maximum increase of 256% compared to the matrix. Additionally, the composites exhibited excellent cooling performance due to their high solar reflectance and thermal emittance. This research provides valuable guidance for the optimization of BN fillers in thermal management and passive cooling applications.

Summary: In this study, an empirical correlation between the tack of phenolic prepregs and the rheological state of the base resin was established through multivariable analyses. The interaction between resin and filler was found to effectively change the resin viscosity, regulating the prepreg tackiness level. By systematically varying the conversion state and operating temperature, inherent phenolic resin properties were thoroughly determined to understand their impact on final composite tack property.

Summary: Carbon nanotubes have great potential for use in microelectronic packaging due to their excellent thermal conductivities. However, their high electroconductibility and poor radial conductivity limit their application in insulating materials. In this study, a heterostructured brushlike hybrid was prepared by anchoring amine-functionalized multiwalled carbon nanotubes onto insulating montmorillonite. The resulting composites exhibited improved thermal conductivity, mechanical properties, and thermal stability, providing a promising strategy for fabricating polymer 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: 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.
