“…1-5 However, due to the surface smoothness and chemical inertness, PBO bers have poor adhesion and low compatibility with resin matrices. 18 Qian et al directly introduced nano-TiO 2 coating to improve the interfacial properties of PBO ber composites, and the test results suggested that the nano-TiO 2 particles on PBO ber surface acted as chocks, which made the ber implanted into resin matrix better. [6][7][8][9][10][11][12] Compared with plasma treatment, high-energy irradiation and chemical oxidation, surface coating, a facile technique of forming a layer of coating with special properties on the material, is very attractive owing to its uniformity.…”

A new method combining surface coating with chemical grafting to prepare poly(p-phenylene benzobisoxazole) fiber-silica-graphene oxide (PBO-SiO 2 -GO) hybrid fiber was proposed. The chemical composition, surface morphology, surface roughness (R a ), surface energy, interfacial shear strength (IFSS), single filament tensile strength (TS) and ultraviolet (UV) resistance of PBO fibers before and after modification were investigated. Experimental results revealed that the PBO fiber surface was covered by a silica coating, onto which GO was successfully grafted through chemical bonds. The R a and surface energy of PBO-SiO 2 -GO were obviously increased in comparison with that of an untreated one. The IFSS of its composites was greatly improved due to the excellent wettability and mechanical interlocking of GO. Meanwhile, TS had no obvious decrease after the surface coating and grafting process.Moreover, the introduction of silica coating on the fiber surface led to a better UV resistance than that of an untreated one. We believe this effective method may provide a novel surface modification strategy for developing multifunctional fibers.

“…However, composite materials also have certain drawbacks, such as poor interfacial adhesion between the reinforcement and the matrix resin, which is a critical factor in the properties of composite materials 5–7. To improve the wettability and adhesion of the carbon fibers to the matrices, much work has been done on the modification of the surface structure of the fiber to improve the interfacial bonding between the fiber and matrix;6, 8 this has included surface treatment of the carbon fiber via various dry and wet oxidation methods,9–11 plasma treatment,5 electrochemical oxidation,12 fiber sizing, and coating 13–15. Among these methods, fiber sizing is effective in improving the shear properties of carbon fiber/resin composites and is preferred because it allows the continuous processing of the carbon fibers.…”

Novel epoxy-modified waterborne polyurethanes (EPUs) were synthesized from toluene 2,4-diisocyanate, poly(ethylene glycol) (PEG), dimethylolbutyric acid, and 2,3-epoxy-1-propanol (glycidol). The chemical structures of the EPU products were characterized by 1 H-NMR and Fourier transform infrared spectroscopy. The thermal properties of the EPUs were examined by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). TGA showed that the EPUs had good thermal stability, with an initial decomposition temperature higher than 250 C. DSC analysis showed that the glass-transition temperature of EPU1 was higher than that of EPU2. When the EPUs were heated above 150 C, the curing reaction took place. In this study, the EPUs were used for carbon fiber sizing. The mechanical interfacial strength between the fibers and the matrix was evaluated by scanning electron microscopy (SEM) and interlaminar shear strength (ILSS) testing. The SEM images of the fracture sections of the composites proved that the interfacial adhesion between the fibers and the matrix improved after the EPU sizing treatment. The composites exhibited the highest value of ILSS after the EPU1 sizing treatment. The excellent properties of the EPUs confer it with potential applications in carbon fiber sizing. EXPERIMENTAL MaterialsHigh-modulus carbon fibers (BHM3, 3K) with tensile strength and elastic modulus values of 3.2 and 420 GPa, respectively, were prepared. PEG (numberaverage molecular weights ¼ 200 and 400) was Correspondence to: Z. Liu (buct1985@126.com).

“…One is to modify the conventional sizing agents, which are mixed with reinforcing nano-fillers such as nano-clays, SiO 2 nanoparticles, carbon nanotubes (CNTs), graphene sheets, and their hybrids [7][8][9][10][11][12]. Even though many works showed good improvements on the interfacial strength, the modification of the sizing agent usually requires unsized-fibers or desizing treatment to reach the best performance.…”
