Summary: The introduction of hyperbranched structure and fluorine groups in epoxy-preFHBPBO significantly improved the mechanical properties and wave-transparent performance of PBO fibers reinforced BADCy resins composites. The addition of 7 wt% epoxy-preFHBPBO increased the flexural strength and interlaminar shear strength, while reducing dielectric constant and dielectric loss compared to PBO fibers/BADCy composites. Moreover, the volume resistivity and breakdown strength were also enhanced in PBO fibers/FHBPBO-co-BADCy composites.

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: In order to meet the diversified requirements for polymer-based composites in modern electronic devices and electrical systems, the simultaneous enhancement of thermal-electrical-mechanical properties is a great challenge. The gradient structured composites, designed by adjusting the distribution of temperature, electric and stress fields in polyethylene (PE) based composites with different Al2O3 contents, demonstrated superior through-plane thermal conductivity, high breakdown strength, and good tensile strength. Finite element simulation provided evidence for the action mechanism on gradient structure regulating temperature and electric field. The strategy of constructing gradient structure provides a feasible route to meet the comprehensive performance requirements of PE based composites in massive manufacture scenario for practical insulation applications.

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: 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.
