Summary: The study found that water-borne polyurethane (WPU) is more conducive to improving the interfacial bonding properties of CF/PC composites, while the addition of CNTs has a beneficial effect on the interfacial properties of composites, but an excessive amount of CNTs can cause agglomeration, which is unfavorable for performance improvement.

Summary: A solvent-free MWCNTs @Fe3O4 nanofluid was used to modify the water-based epoxy sizing agent for CFRPs. The addition of 2% MFNF significantly improved the mechanical properties of CFRPs, with ILSS and bending strength increased by 21.69% and 39.51%, respectively. Moreover, the Thermal conductivity was improved by 112.23% due to the excellent TC possessed by MWCNTs and the orientation of MFNF in thermal conductivity, which facilitates phonon propagation at the interface.

Summary: An aqueous polyurethane sizing agent was used to continuously treat anodized carbon fiber tow in order to enhance the interfacial properties of carbon fiber-reinforced polyurethane composites. Experimental results indicate that the sizing agent significantly improves the interfacial properties, as evidenced by the increase in interlaminar shear strength (ILSS). Further heat treatment resulted in a higher ILSS value, suggesting that the sizing agent promotes the reaction between the resin matrix and the carbon fiber surface. Overall, the polyurethane sizing agent shows promise in improving the interfacial properties of carbon fiber-reinforced polyurethane composites.

Summary: The N-(4-hydroxyphenyl) maleimide (4-HPM) modified waterborne polyurethane emulsions (MWPU) were used as surface sizing agents to improve the interfacial adhesion between carbon fibers (CF) and epoxy resin matrix. The modified MWPU showed good particle size distribution, storage stability, and thermal stability. The surface reactivity of CF increased significantly after sizing. The interfacial shear strength (IFSS) and the interlaminar shear strength (ILSS) of CFREs were greatly improved by the MWPU emulsion, especially when the 4-HPM content was 1.0 wt%.

Summary: The surface of carbon fibers is modified by a sizing agent composed of sulfonated polyether ether ketone (SPEEK) and carboxylated carbon nanotubes (MWCNTS), which improves the interfacial binding between carbon fibers and polyetheretherketone (PEEK) matrix. The flexural strength and interlaminar shear strength of the modified composites are significantly enhanced by 74.2% and 84.2% compared to CF/PEEK composites without sizing agent. Coating with SPEEK-MWCNTS is confirmed to be an essential approach to construct an excellent interface between the reinforcement phase and thermoplastic matrix.

Summary: A hyperbranched waterborne polyurethane sizing agent with high-solid content was designed to improve the interfacial adhesion of carbon fiber/polyamide-6 composites. By controlling the sizing agent concentration, the interlaminar shear strength and flexural strength of the composites were effectively increased. The preparation of this sizing agent is simple and environmentally friendly, which may reduce transportation costs.

Summary: This study developed aramid fiber-phenolic matrix composite laminates reinforced with carbon nanotubes (CNT) and systematically investigated their interfacial and mechanical properties. The results showed that short CNTs were critical to the performance of the laminates, while long CNTs did not effectively improve the properties. Excellent dispersion and functionalization of the CNTs were also beneficial for enhancing the properties.

Summary: A solvent-free GO@Fe3O4 nanofluid hybrid water-based sizing agent was prepared and applied to improve the interface properties and thermal conductivity of carbon fiber reinforced polymers. The GFNF CF/EP composites showed significantly enhanced performance compared to commercial CF/EP composites, with improvements in interfacial properties and thermal conductivity. The enhanced properties were attributed to the uniform adhesion of GFNF to the CF surface, promoting physical-chemical interaction, stress dispersion, and prevention of cracking, as well as the formation of continuous thermal conduction pathways at the interface.

Summary: In this study, a carbon nanotube (CNT)-reinforced aluminum alloy matrix composite with enhanced mechanical properties was fabricated using the Mixed Ball-Milling (MBM) technique. High-resolution scanning transmission electron microscopy (HRSTEM) imaging, combined with Raman spectroscopy, was used to investigate the microstructure and mechanical behavior of the composite. The results showed that the MBM method not only maintained the integrity of the CNT structure but also allowed for tailoring of the interfacial bonding structure. Additionally, the presence of oxide species in the MBM processing limited the formation of aluminum carbide (Al4C3).
