“…In [ 4 ] Meghashree Padhan suggested some examples of hybrid ‘PEEK + PAEK’-based composites loaded with 30% short carbon fibers (SCFs) and 10% graphite (Gr) nanoparticles as primary solid lubricants (SLs), as well as 10% noncarbon secondary SLs such as WS 2 , MoS 2 , h-BN, etc. When interpreting the results, the effect of synergism between both types of SLs and the best efficiency of nanoparticles over microsized inclusions were considered.…”

“…However, the number of asperities on the sliding surfaces, determining CoF levels, also depends on the contact area. Three contact types are typically distinguished in tribology: point, line, and area ( Figure 3 ) [ 4 ]. It is not too difficult to form a TF that is uniform in thickness and relatively firmly adhered on the surface of a steel ball at a point contact; however, this task becomes highly complicated for area contact types.…”

High Performance Polymer Composites: A Role of Transfer Films in Ensuring Tribological Properties—A Review

2022

View full text Add to dashboard Cite

The purpose of this review is to summarize data on the structure, mechanical and tribological properties, and wear patterns of composites based on high-performance polymers (HPPs) intended for use in friction units. The review includes three key sections, divided according to the tribological contact schemes regardless of the polymer matrix. In the second part, the analysis of composites is carried out in point contacts. The third section is devoted to the results of studies of HPP-based composites in linear ones. The fourth section summarizes information on flat contacts. Particular attention is paid to the formation of transfer films (TFs) in the contacts and their influence on the tribological patterns of the studied rubbing materials. As a conclusion, it is noted that the challenge of experimental methods for analyzing TFs, stated by K. Friedrich, is effectively solved in recent studies by the XPS method, which enables us to accurately determine their composition. Although this determination is completed after the tribological tests, it allows not only a more accurate interpretation of their results considering specific conditions and loading schemes, but also the ability to design HPP-based composites that form required TFs performing their preset functions.

“…Studies on tribological behavior of polymer nanocomposites up to the year 2017 were reviewed [ 27 , 28 ]. Later, review papers on tribological properties of polymer nanocomposites were limited to epoxy-, polyurethane-based nanocomposites coatings [ 29 ] and poly(ether ketone) nanocomposites [ 30 ]. However, to date, a comprehensive and up-to-date review for the tribological studies on thermoplastic and thermoset polymer nanocomposites conducted since 2017 has not been reported.…”

Polymer nanocomposites with enhanced performances are becoming a trend in the current research field, overcoming the limitations of bulk polymer and meeting the demands of market and society in tribological applications. Polytetrafluoroethylene, poly(ether ether ketone) and ultrahigh molecular weight polyethylene are the most popular polymers in recent research on tribology. Current work comprehensively reviews recent advancements of polymer nanocomposites in tribology. The influence of different types of nanofiller, such as carbon-based nanofiller, silicon-based nanofiller, metal oxide nanofiller and hybrid nanofiller, on the tribological performance of thermoplastic and thermoset nanocomposites is discussed. Since the tribological properties of polymer nanocomposites are not intrinsic but are dependent on sliding conditions, direct comparison between different types of nanofiller or the same nanofiller of different morphologies and structures is not feasible. Friction and wear rate are normalized to indicate relative improvement by different fillers. Emphasis is given to the effect of nanofiller content and surface modification of nanofillers on friction, wear resistance, wear mechanism and transfer film formation of its nanocomposites. Limitations from the previous works are addressed and future research on tribology of polymer nanocomposites is proposed.

“…Despite their many benefits, however, CF‐reinforced PEEK composite materials are limited by the following characteristics 10,11 CF and PEEK surfaces are inert and do not bond chemically. PEEK has a high melting viscosity that renders the resin matrix unable to infiltrate the CF surface completely. The surface of CF is relatively smooth, and the mechanical interlocking between the resin matrix and CF is poor. Aiming to improve the interfacial interaction between PEEK and CF, scholars have mainly carried out research from three aspects 12,13 : (1) modification of PEEK resin matrix, (2) modification of CF surface, and (3) preparation of high‐performance sizing agents to improve the adhesion between PEEK and CF. Zhang et al 14 prepared soluble phenylethynyl–PEEK (PEP‐PEEK) and obtained a new CF/PEEK composite material by the melt impregnation method.…”

The interfacial interactions of carbon fiber (CF)‐reinforced polymer composites is a key factor affecting the overall performance of the material. In this work, we prepared a sulfonated poly(ether sulfone)–graphene oxide mixed sizing agent to modify the interface of CF/PEEK composites and improve the interfacial properties between the PEEK matrix and CF. Results showed that the mechanical and interfacial properties of CF/PEEK composites are improved by the sizing agent. Specifically, the flexural strength, flexural modulus and interlaminar shear strength of the materials reached 847.29 MPa, 63.77 GPa, and 73.17 MPa, respectively. Scanning electron microscopy confirmed markedly improved adhesion between the resin matrix and fibers. This work provides a simple and effective method for the preparation of high‐performance CF/PEEK composites, which can improve the performance of composites without degrading the mechanical property of pristine CF.
