Summary: The copolymer membrane and AHHFP grafted onto the surface of PBO fibres enhances the interfacial strength and reduces interfacial polarization of the wave-transparent laminated composites. The resulting 6F-PBO@P-GMA fibres/modified cyanate ester composites exhibit higher flexural strength and interlaminar shear strength compared to composites with pristine PBO fibres, with excellent wave-transparency properties at X-band.

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: 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: Graphene oxide (GO) or reduced graphene oxides (RGO) have shown great potential as reinforcements in epoxy composites for enhancing their mechanical and thermal properties. However, the preparation of GO and RGO is challenging. This study proposes the use of milled graphite nanoparticles (GrNPs) as an alternative reinforcement due to their porous structure and ease of oxidation. The use of economical silanized milled GrNPs significantly improves the thermo-mechanical behavior of the epoxy nanocomposites without sacrificing other important properties.

Summary: In this study, flexible and rigid polyurethane/copper composites were prepared via a simple solution casting process. The dispersion and chemical bonding of the filler were investigated, and the thermal properties and mechanical properties of the composites were analyzed. The results showed that the thermal conductivity of the composites was significantly improved compared to the pure polyurethane, and the mechanical properties were also enhanced. The study suggests that copper microparticles can serve as an active filler in both flexible and rigid polyurethane matrices.

Summary: This study compares the thermomechanical behavior of different materials under accelerated ageing conditions, including insulation materials using recycled rubber and other comparison materials. Among them, aerogel-based materials showed superinsulation behavior and good flexibility, while extruded polystyrene exhibited permanent deformation under compression. In general, ageing conditions led to a slight increase in thermal conductivity, which disappeared after drying of the samples in an oven, and a decrease in Young's moduli.

Summary: Through a simple manufacturing technology, we have successfully developed 4D printed shape memory biocomposites with controllable transition temperature, and realized the shape memory process under near-body temperature conditions. These biocomposites fill the gap in 4D printed intestinal stents and have the characteristics of customization, reconfigurability, biodegradability, and biocompatibility. Compared to metal intestinal stents, the biodegradability of these biocomposites can avoid the need for a second endoscope removal. This work not only provides an efficient and simple methodology for fabricating NBT-triggered 4D printing shape memory biocomposites, but also demonstrates the application potential of 4D printed intestinal stents in next-generation intelligent implants.

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.
