“…However, when it comes to CF‐SiO 2 /PA6 and CF‐PDA‐SiO 2 /PA6 composites, the T g was increased to about 80.0°C, approximately. The increment in Tg might result from the two reasons: the enhanced mechanical interlocking between CFs and PA6 restrained the mobility of the molecular chains of matrix; Moreover, the improved interaction between CF and PA6 caused the change in molecular chain mobility near the nano‐SiO 2 particles and a reduction in free volume 35,40–42 …”

Carbon fiber (CF) reinforced matrix composites have been applied widely, however, the interfacial adhesion of composites is weak due to smooth and chemically inert of CF surface. To solve this problem, A polydopamine/nanosilica (PDA-SiO 2 ) interfacial layer on carbon fiber surface was constructed via polydopamine and nano-SiO 2 (CF-PDA-SiO 2 ) by a facile and effective method to reinforce polyamide 6 composites (CFs/PA6). The effects of PDA-SiO 2 interfacial layer on crystallization structure and behavior, thermal properties, and mechanical properties of CFs/PA6 composites were investigated. Furthermore, interfacial reinforcement mechanism of composites has been discussed. This interfacial layer greatly increased the number of active groups of CF surface and its wettability obviously. The tensile strength of CF-PDA-SiO 2 /PA6 composites increased by 28.09%, 19.37%, and 26.22% compared to untreated-CF/ PA6, CF-PDA/PA6, and CF-SiO 2 /PA6 composites, respectively, which might be caused by the increased interfacial adhesion between CF and PA6 matrix. The thermal stability, crystallization temperature, crystallinity, and glass transition temperature (T g ) of CF-PDA-SiO 2 /PA6 composites improved correspondingly, attributing to the heterogeneous nucleation of nano-SiO 2 in the crystalline area and hydrogen bonds with molecular chains of PA6 in the amorphous area. This work provides a novel strategy for the construction of interfaces suitable for advanced CF composites with different structures.

For the purpose of improving the interface and mechanical properties of carbon fiber reinforced polymer (CFRP) composites, a new strategy was proposed to graft the graphene oxide (GO) onto carbon fiber (CF) surface fast and effectively via thiol‐ene click chemistry reaction using vinyl‐terminated hyperbranched polyester (VHBP) as bridging agent. The successful synthesis of the CF‐VHBP‐GO hybrid reinforcement was verified through Fourier transform infrared spectroscopy (FT‐IR), x‐ray photoelectron spectroscope, thermogravimetric analysis, and scanning electron microscopy. The simultaneous introduction of GO and hyperbranched polymers changed the fiber surface morphology and improved the wettability and surface energy of CF. Judging from the results of the micro‐droplet test, the interfacial shear strength for epoxy (EP) based composite reinforced with CF‐VHBP‐GO was significantly increased by 137.8% compared to untreated CF/EP composite owing to the synergistic effect of VHBP and GO. In addition, the tensile and flexural strength for CF‐VHBP‐GO/EP composite were improved by 47.6% and 65.8%, respectively, compared to untreated CF/EP composite, respectively. This work offers a promising technique for developing high‐performance CF composites with excellent interface properties.

“…Therefore, CFRTP has been increasingly used in aerospace, transportation, semiconductor and biomedical fields for secondary‐force‐bearing and non‐force‐bearing components. [ 5– 7 ] Examples include, tail elevators and rudders, floor panels of Gulfstream Aerospace G650, [ 8 ] engine cowlings for the Airbus A380, [ 9 ] composite hip prostheses, [ 10 ] and implant components for orthopedic and trauma applications. [ 11 ] Although CFRP is mostly processed by the near‐net shapes methods such as filament winding, autoclave molding or compression molding, secondary machining operation is often necessary to meet stringent assembly requirements in terms of dimensional tolerance and surface quality.…”

“…[25] Significant differences exist in the mechanical and thermal properties of the constituent phases, and the fiber/matrix interface is also an important factor to consider, leading to the complex interactions between the matrix and CFs during grinding. [7] Existing research on the grinding of CFRP tends to focus on the grinding forces, grinding temperature, surface quality and material removal mechanism. For example, Hu et al [26,27] performed grinding of unidirectional and multidirectional CF/epoxy on a surface grinder MININI M286 CN, focusing on the chip formation, material removal mechanism, grinding surface features and grinding force characteristics.…”

Grinding performance study of CF/epoxy and CF/PEEK composites

In order to distinguish the grinding performance of the thermoset and thermoplastic carbon fiber‐reinforced plastic (CFRP) composites, carbon fiber‐reinforced epoxy resin (CF/epoxy) and carbon fiber‐reinforced poly‐ether‐ether‐ketone (CF/PEEK) composites were employed in this study. Different process parameters were set to grind the two materials. Then the surface morphologies and roughness of the workpieces with different process parameters were observed and measured. Experimental results indicated that the grinding forces were positively correlated with the grinding depth and feed speed, and negatively correlated with the wheel speed. The grinding depth was the main influencing factor of the maximum temperature of the grinding. The heat distribution of the grinding process was dependent on the fiber direction. In addition, the chip formation mechanism of CF/epoxy and CF/PEEK were investigated. Compared with CF/epoxy, the grinding forces and temperature were higher and the wheel was more prone to be clogged under the same grinding parameters, indicating that it was more difficult to process CF/PEEK. However, the surface quality of CF/PEEK with high ductility was much better than CF/epoxy.
