Summary: The authors proposed a novel approach based on Diels-Alder (DA) chemistry to tackle the challenge of manufacturing highly filled composite materials. By crosslinking PCLolig and connecting it to maleimide functionalized Al2O3 particles, a covalent adaptable composite network was formed, enabling effective dispersion of high-concentration fillers and increased strength in the final composite material.

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: 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 effects of cooling rates on the crystallization behavior, interfacial bonding strength, interlaminar fracture toughness and low-velocity impact performance of carbon fiber reinforced poly(aryl ether ketone) (PAEK) and poly(ether ether ketone) (PEEK) composites. The results show that PAEK has lower crystallinity and smaller crystals compared to PEEK at the same cooling rate. The lower crystallinity and smaller crystals of PAEK contribute to improved matrix ductility and interfacial bonding strength in the composites. Under water cooling conditions, the impact damage area of CF/PAEK is about 71% lower than that of CF/PEEK, while the CAI is about 14% higher.

Summary: Inspired by the double-helicoidal structure of coelacanth fish scales, engineering composite materials with enhanced toughness were designed and fabricated in this study. The double-helicoidal composites exhibited higher dynamic energy absorption and more complex failure modes compared to single-helicoidal counterparts, allowing for greater design flexibility without being sensitive to fiber orientations. Additionally, interlaminar stresses were found to be responsible for delamination in the double-helicoidal composites. These findings contribute to the development of next-generation impact-resistant composite materials.

Summary: This paper investigates the tool-ply friction behavior of jute/PLA biocomposites in thermoforming. A pull-through friction testing device was developed to characterize the tool-ply friction behavior of jute/PLA prepreg at elevated temperature. The effects of alkali treatment, fiber orientation, normal force, and slipping velocity were studied, and a quantitative definition of tool-ply friction behavior was achieved. The results indicate a strong relationship between tool-ply friction behavior and woven and fiber structures, indicating hydrodynamic lubrication.

Summary: Micro-arc oxidation (MAO) treatment was used to modify aluminum (Al) alloys in order to improve bond strength with carbon fiber reinforced polymer (CFRP). The treatment successfully created a porous surface with better hardness, roughness, and wetting, and introduced resin pre-coating (RPC) and carbon nanotube (CNT) fiber bridging to improve the bonding interface. The combined treatments significantly increased the bond strength by up to 156.1%, indicating the feasibility of MAO as an alternative method for manufacturing high-performance Al-CFRP composites in industrial production.

Summary: Faster heating rates and higher process temperatures can reduce the total process time while achieving the same degree-of-cure. Thermal analysis shows that thermoplastic interleaf particles melt at the recommended curing temperature. A short dwell at a lower temperature can prevent the mixing of thermoplastic particles and thermoset pre-polymer.
