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: 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.

Summary: In this study, high-performance polyimide (PI) fibers with excellent interfacial adhesion and mechanical properties were successfully developed by introducing 4,4'-diamino-(1,1'-biphenyl)-3,3'-diol (HAB) diamine into the molecular chains. The fibers exhibited an interfacial shear strength (IFSS) value of 46.33 MPa, tensile strength of 2.62 GPa, and modulus of 100.15 GPa. The introduction of HAB moiety contributed to the reduction of microvoid radii in the fibers, leading to significant enhancement in their mechanical properties. The surface activity of the synthetic fibers was confirmed by X-ray photoelectron spectroscopy and static contact angle measurements, and the enhanced interfacial adhesion in PI fiber/epoxy resin composites was demonstrated. This study provides an effective strategy to address the long-standing challenges in the PI fiber-reinforced polymer matrix composites industry.

Summary: This study investigated the relationship between surface properties of CFs and interfacial properties of CF/PPS composite. The results showed that desizing of CFs led to increased roughness and decreased content of functional groups on the CF surface. The dispersive component of surface energy increased, while the polar component decreased after desizing. The interfacial shear strength of CF/PPS composite remained almost constant after CF desizing. It was concluded that surface energy of CFs plays a role in interfacial crystallinity but is not the critical factor for interfacial strength of CF/PPS composite.

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: Polyacrylonitrile (PAN) nanofiber-sheathed Basalt fibers (BFs) were prepared using the electrospinning method and further used to synthesize novel BFs-reinforced epoxy composites with enhanced interfacial properties, showing a 31.33% increase in interfacial shear strength (IFSS). The improvement mainly comes from the formation of a gradient interfacial layer, enabling uniform stress transfer and promoting interfacial adhesion between BFs and the epoxy matrix. This method is suitable for cost-efficient, continuous large-scale production.
