Summary: An organic-inorganic hierarchical structure was formed by self-assembled MXene and chitosan on carbon fiber surfaces, improving the interfacial performance of CF/epoxy composites. The enhanced wettability and surface energy from active groups of MXene and CS greatly boosted interfacial adhesion. The increased roughness and the formation of hydrogen and covalent bonds contributed to better mechanical interlocking and crack deflection at the fiber-matrix interface.

Summary: In this study, carbon fibers were oxidized with concentrated hydrochloric acid and then modified in two steps. First, ?-aminopropyltriethoxysilane (KH550) was grafted on the oxidized carbon fibers to build a platform on the fiber surface, followed by grafting of epoxy functionalized elastomer (EVMG) on the carbon fiber surface. Chloroprene rubber/natural rubber/carbon fiber (CR/NR/CF) composites were prepared by mechanical blending process. Characterization of carbon fibers was conducted using different techniques, including X-ray photoelectron spectroscopy (XPS), thermal gravimetric analysis (TGA), scanning electron microscopy (SEM), and dynamic mechanical analysis (DMA). The results revealed that the EVMG modification enhanced the interface adhesion between the fiber and rubber. The presence of a macromolecular film on the carbon fiber surface by EVMG increased surface roughness and introduced epoxy groups, facilitating physical entanglement between carbon fiber and rubber and enhancing interfacial bonding through chemical interactions. Furthermore, the EVMG modification resulted in a significant increase in tensile strength, 300% constant tensile stress, and wear resistance of the CF composite.

Summary: Different rigid-flexible structures were studied to understand their influence on the interface strength of carbon fiber/epoxy composites. The optimal interfacial shear strength and interlaminar shear strength were 86.7 MPa and 85.4 MPa, respectively, with a polymerization time of 12 hours. The impact toughness and tensile strength of the composites increased with polymerization time growth, while the conductivity decreased.

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: A multi-scale reinforcement material of carbon fiber/carbon nanotubes (CF/CNTs) was prepared using a one-step dipping method, with significant improvements in wettability, chemical activity, and tensile strength of the modified CFs. The synergistic effect of the silane coupling agent and CNTs enhanced the interfacial properties of the composite material. The bridging effect of CNTs as an interfacial reinforcing mechanism was proposed, showing promising potential for surface modification and interfacial enhancement of CF materials.

Summary: Carbon fiber-reinforced polymer (CFRP) composites have ultra-strong and lightweight characteristics, but the weak interfacial interaction between untreated carbon fiber surface and the polymeric matrix leads to catastrophic failure of the composite material. Graphene oxide (GO) has been applied to improve the interfacial adhesion between fiber and matrix and enhance CFRP properties. The peculiar structure of GO nanoparticles allows strong interaction with the matrix and reinforcing carbon fibers, leading to improved interfacial adhesion and enhanced properties of the composite material.

Summary: In this study, the modulus difference between carbon fiber (CF) and resin was reduced and a gentle modulus transition was achieved through the structural design of CF and resin, which resulted in enhanced interfacial properties of the CF/EP composite. A multi-stage modulus gradient decreasing structure was constructed, dispersing external stress effectively for excellent interface properties. The bi-directional structural design increased the ILSS of CF/EP composites, providing new ideas for improving the mechanical properties of CF composites.

Summary: A hierarchical structure consisting of carbon nanotubes (CNTs) grown on carbon fiber (CF) was prepared using a novel vacuum-assisted chemical vapor deposition (CVD) method. The CNTs-grown CF significantly improved the interfacial adhesion of epoxy composites by enhancing the mechanical interlocking between the fiber and the resin and inducing the formation of interphase. The CNTs also exhibited energy absorption and increased the difficulty of separation between the fiber and resin.
