“…Compared to CF‐PDA/PA6 composites, more adhered PA6 on the CF surface was observed in CF‐PDA‐SiO 2 /PA6 composites (Figure 7d), which reflected stronger interfacial adhesion between CF and PA6 matrix. The above results illustrated that the amount of PA6 adhesion on the CF surface was relevant to the varying trend of their tensile strength 39 …”

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.

A double grafted interfacial layer on CF surface was constructed via PDA and nano-SiO2 (CF-PDA-SiO2) by a facile and effective method to reinforce polyamide 6 composites (CFs/PA6). The effects of double grafted interfacial layer on crystallization structure and behavior, thermal properties, and mechanical properties of CFs/PA6 composites were investigated. This interfacial layer greatly increased the number of active groups, roughness and wettability of CF surface, the tensile strength of CF-PDA-SiO2/PA6 composites increased by 28.09%, 19.37%, and 26.22% compared to untreated-CF/PA6, CF-PDA/PA6, and CF-SiO2/PA6 composites, respectively, which might be caused by the increased interfacial adhesion between CF and PA6 matrix. The thermal stability, crystallization temperature, crystallinity, as well as glass transition temperature (Tg) of CF-PDA-SiO2/PA6 composites improved correspondingly, attributing to the heterogeneous nucleation of nano-SiO2 in the crystalline area and hydrogen bonds with molecular chains of PA6 in the amorphous area. Furthermore, interfacial reinforcement mechanism of composites have been discussed.

“…The coating is characterised by a stable structure and performance at high temperature, good compatibility with CF and matrix, low shear strength and certain thickness. 16,30,31 Generally, the interfacial properties of CFRTCs are characterized by interfacial shear strength (IFSS) and interlaminar shear strength (ILSS). We summarize the flexural strength, ILSS and IFSS of CF/PEEK composites after treating CF with different sizing agents (Table 1).…”

As a high‐performance thermoplastic polymer, poly(ether‐ether‐ketone) (PEEK) has excellent thermal stability and mechanical properties; it is widely used in the aerospace field. However, PEEK has high viscosity, high processing temperature and poor fluidity in the molten state. In preparing carbon fibre (CF)/PEEK composites, poor impregnation performance will occur, resulting in high porosity and poor mechanical properties of the CF/PEEK composites. This mini‐review focuses on improving the interface of the CF/PEEK composite by coating the CF surface and introduces the preparation of CF/PEEK composites by coating CF with a resin‐based sizing agent, a mixed sizing agent and nanoparticles. Meanwhile, the properties of CF/PEEK composites prepared by different coating methods are compared. © 2022 Society of Industrial Chemistry.
