Summary: This manuscript presents a rapid surface modification method for carbon fibers using small molecules in polypropylene composites. The attachment of n-butylphenyl species onto the fiber surface improved the toughness by 32% and 30% at 10% and 40% weight fractions respectively. The embedded fiber length, fiber weight fraction, and polymer thermal properties were not affected by the modification, suggesting that the mechanical performance changes originated from the installed surface chemistry blending with the polymer phase.

Summary: Recent studies have shown that the carbon-rich region in carbon fiber epoxy composites can be called an interphase, and that the addition of graphene nano-platelets can significantly influence the properties of the interphase. The effects of graphene nano-platelets on transverse loading and in-situ strains during longitudinal tensile loading have been investigated, demonstrating improved performance of composites with GNP-coated fibers. The SEM analysis further confirms that GNP addition leads to fewer fiber breaks and enhanced fiber-epoxy adhesion under shear loading.

Summary: Among natural fibers, basalt fibers have recently emerged as the main candidate to replace glass fibers in composite materials. The aim is to optimize the load transfer efficiency between the two different phases in the composite by growing carbon nanostructures on the surface of unsized basalt fibers using less common catalysts. By lowering the synthesis temperature, the intrinsic properties of the basalt fibers were preserved and dense and uniform carbon nanostructures were obtained. These less common catalysts provide an expanded design strategy for obtaining composites with improved interfacial bonding and multifunctional properties.

Summary: Addition of graphene nanoplatelets (GNP) improves mechanical properties and wear performance of carbon fiber reinforced epoxy composites. Optimum amount of GNPs coated on oxidized carbon fibers shows the least wear debris and enhanced fiber-epoxy bonding. Wear response is correlated with the size of the interphase formed between the fiber and the epoxy.

Summary: In this study, soluble phenolphthalein polyaryl-ether-ketone polymers were synthesized and used to prepare water-based sizing agents, significantly improving the interfacial adhesion of CF/PEEK composites. The sizing agents showed high solubility, excellent thermal properties, and good storage stability, leading to a significant enhancement in bending strength and interlaminar shear strength of the composites. An illustrative mechanism for the interfacial reinforcement effect of the sizing agent was proposed, providing an effective and green method for enhancing the interfacial properties of CF/PEEK composites.

Summary: Compared with traditional devices, one-dimensional coiled carbon nanotube yarn-based devices offer advantages for wearable, downsizing, and implantable applications. However, coiled CNT yarns have structural instability. To overcome this, we propose micro-scale CNT buckled core-sheathed fibers that have electrochemical multifunctionalities and maintain electrical performance under high stretchability conditions. These fibers exhibit improved capacitances and can generate electrical energy under directed tensile strain. These multifunctional CNT buckle fibers have prospects in various applications, including stretchable electrodes, energy storage, and energy harvesting.

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.

Summary: In response to the global environmental pollution crisis caused by waste plastics, recyclable design is an effective solution. A CPVC/PUA nanocomposite foam was developed using the plasticizing-foaming-reinforcing strategy, combined with catalytic carbonization. The foam exhibited high expansion ratio, robustness, solvent resistance, flame-triggered shape memory effect, and ablation resistance. The foam could be directly upcycled into functional carbon foam with attractive electromagnetic interference shielding performance.
