Summary: Electrothermal processes were investigated in pyroresistive composites of high-density polyethylene with carbon black and carbon fibers. The kinetic heating curves showed an exponential dependence with a heating rate constant for each composite. Equilibrium temperature was reached after a short heating time, and decreased with the presence of positive temperature coefficient of resistance (PTC) effect. The composites exhibited self-regulating capability and the equilibrium temperature depended on the applied voltage and electric power with different relationships. An application of using HDPE-CB composite as a heating element for resistance welding was demonstrated.

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: In this study, a small amount of conductive copper micro-particles were added to multi-walled carbon nanotube/polydimethylsiloxane composites to enhance their electromagnetic wave shielding performance. The addition of copper micro-particles increased the propagation paths of electromagnetic waves inside the composites, resulting in a remarkable improvement in electromagnetic wave shielding. The diameter and content of the copper micro-particles were investigated, and the shielding mechanism of the composites was simulated and verified by electromagnetic simulation. The composites exhibited an absorption-type shielding mechanism with low reflection loss and reflectivity coefficient.

Summary: Elastomer composites with temperature and strain-induced tunable EMI shielding effectiveness were successfully obtained by introducing temperature-sensitive microspheres (TSM) into PDMS/CNT mixture. The mechanism of temperature and strain-induced regulation on EMI shielding was investigated, showing that TSM particles could rearrange the CNT conductive network at specific temperature and strain levels. Temperature-induced regulation led to a decrease in EMI SE at 120°C, partially recovering at 150°C, while strain-induced regulation resulted in reduced EMI SE after 70% compression, partially recovering at 120°C.

Summary: This paper investigates the effect of impact damage on the fatigue behavior of CF/PEEK-titanium hybrid laminates. A fatigue life model is proposed to predict the S-N curves of the laminates based on energy dissipation approach. The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined. The validity of the proposed model is verified through fatigue tests under different stress ratios and impact energy levels.
