“…This is mainly due to the formation of root‐like structures on the surface of CF after the addition of nanoparticles, which enhances the surface roughness, thereby generating nanoscale mechanical linkages at the interface.

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.

“…Experimental investigations have reported that the friction coefficient of PEEK reinforced with carbon fiber (CF) against Co-Cr-Mo alloy was effectively reduced and the wear rate was reduced compared with pure PEEK because CF could reduce shearing and bear the load preferentially [20,21]. Cao and Dong [22,23] found that a continuous and relatively uniform CF-PEEK transfer film on a textured WC-Co surface was produced via the microcutting effect of dimple texture edges on the material removal of the counterpart CF-PEEK pin, and the stable reduction in the friction coefficient was nearly 38.3% compared to the nontextured surface. Onodera and Haidar et al [24,25] elucidated the mechanism of the excellent tribological performance of a PEEK polymer composed of PTFE by investigating the microstructure and function of the transfer film via XPS analysis with the argon etching technique, and the results showed that the transfer film to metallic surfaces was probably a gradient structure accompanied by a PTFE film on the topmost surface and a PEEK film mainly on the inside to reduce the friction.…”

With the aim of promoting the qualities for total hip joint replacement, the wettability and tribological behaviors of PEEK composites pins with two sets of different fillers (PEEK/CF or PEEK/CF/PTFE/graphite) against Co-Cr alloy discs with five categories of surface textures (polished, orthogonal, spiral, r-θ, and orthogonal combined with spiral) were explored. It is revealed that the existence of CF in PEEK matrix increases the hydrophilicity in addition to the strength of PEEK, while the addition of PTFE increases the hydrophobicity of PEEK. The Co-Cr alloy discs with hydrophilic properties can be adjusted as hydrophobic, with the depth of textured grooves exceeding the critical sag height determined by the contact angle and the groove width. It can be concluded that PEEK/CF/PTFE/graphite composite has a lower wear rate than PEEK only reinforced with CF against Co-Cr alloy, both without surface texture and with shallow or deep grooves. The existence of shallow grooves on the disc surface could help the PEEK blends to achieve a steady friction against Co-Cr alloy in addition to collecting the worn debris. PEEK blend pins with 10 vol% CF, 10 vol% PTFE and 10 vol% graphite can achieve a lower friction coefficient of no more than 0.2 against Co-Cr alloy discs with shallow grooves around 3.5 μm in orthogonal or spiral textures.

“…Yang et al [15] proposed that the collision frequency between friction counter faces is the main factor affecting the tribological properties of grooved surfaces. Cao et al [16] indicated that the wear debris removed from the PEEK pin due to the microcutting effect of the dimple texture developed into tribofilms by repetitive friction cycles. Wang [17] designed and prepared circular dimples on polymer specimens, which revealed a stable friction coefficient and lower wear rates.…”

Tribological Properties of Carbon Fiber-Reinforced PEEK against 304 Stainless Steel with Reticulate Surface Texture

With the aim of improving the durability and reliability of polyetheretherketone (PEEK) composites reinforced with carbon fiber (CF) as thrust bearings without lubricants, a reticulate surface texture was fabricated by plane honing on a stainless steel (SS) counterpart to promote its tribological properties. Pin-on-disk experiments were designed, with the results showing that the reticulate surface texture effectively reduces the friction coefficient from 0.40 to 0.20 compared with the polished SS surface, within the range of the pv value from 0.185 to 1.85 MPa∙m/s. The wear mechanism of the polished SS surface against CF-PEEK, proven with SEM and EDS observations as well as AE measurements, is revealed, falling into abrasive wear with SS particles embedded in the friction interface around the CF strips, causing three-body contact. The reduction in the friction coefficient of the textured SS disk against the CF-PEEK pin can be achieved due to diminution of the CF wear debris and SS particles, which are scraped off by the groove edges and trapped by the groove valleys, reducing the three-body abrasive wear, while the honed plateau is used as a flank surface like a cutting tool to scratch more soft PEEK particles as the transferred film, owing to adhesive wear. This investigation suggests that the SS disk with a honed surface structure can be used as the counterpart of CF-PEEK bearings with a low friction coefficient and wear rate under dry friction.
