A high efficient method for introducing reactive amines onto carbon fiber surfaces using hexachlorocyclophosphazene as a new coupling agent

Influence of carbon nanotubes coatings onto carbon fiber by oxidative treatments combined with electrophoretic deposition on interfacial properties of carbon fiber composite

“…morphology ( Fig. 3(b)), the similar phenomenon was reported in Refs [29,30], oxidative treatment of CF only remove the little residual polymer sizing or a thin layer of the weakly bonded materials at apparent surface of carbon fiber, which did not affect the CF strength. As shown in Fig.…”

Improving the interfacial property of carbon fiber/PI resin composite by grafting modification of carbon fiber surface

“…Generally, they can improve the wear resistance of composites because of the increase of loading capability, while it is unclear under what conditions CFs can induce low friction coefficient . According to Wang and Zhang, the incorporation of CFs can significantly improve the friction‐reducing and anti‐wear abilities of polyimide (PI) under dry sliding conditions, while Li and Cheng found the incorporation of CFs into PI can generally reduce the wear rate of composites, but may either increase or reduce the friction coefficient with different CF contents. Aromatic PI fiber has been recognized as one of the most important high‐performance polymeric fibers with superior performances such as excellent thermal stability, good chemical resistance, radiation shielding capability, and so on .…”

Improving the interfacial property of carbon fibre/epoxy resin composites by grafting amine‐capped cross‐linked poly‐itaconic acid

“…In comparison with the reported interfacial and monofilament tensile strength improvements of CF based on other modified methods, the advantage of this work was shown in Figure . Some modified methods had successfully improved IFSS of composites but have declined the monofilament tensile strength of CFs . In contrast, the other methods increased IFSS of composites without damaging monofilament tensile strength even improving slightly .…”

“…Flaws on the CF surface can act as stress concentration points for growth and propagation of cracks, leading to fibre fracture and matrix failure within the composites . In recent decades, numerous methods have been used to increase the polarity and activity of CF surfaces to enhance the interfacial properties of CFRPs, including strong acid treatment, electrochemical oxidation, coating treatment, plasma treatment, and chemical grafting . For example, Wu et al prepared a hierarchical reinforcement (CF‐g‐SiO 2 ) through directly grafting 3‐aminopropyltriethoxysilane (APS) functionalized silica nanoparticles (SiO 2 ‐APS) onto the CF surface.…”
