“…As matrices, various polymers are being used, with epoxy, the most commonly used thermosetting polymer due to its high mechanical characteristics, moisture, and corrosion resistance. The fiber reinforcement improves the loadbearing capability in the polymer matrix [9][10][11]. In addition, polymer composites reinforced with woven fiber have better wear properties [12].…”

In this research, carbon fiber and Graphene nanoplatelets (GNP) of different weight percentages of GNP (0, 0.1,0.3, and 0.5 wt.%) reinforced hybrid composites were fabricated via hand layup technique followed by compression molding. For wear analysis to understand the correlation between control parameters (wt.% of filler, normal load, velocity, and sliding distance) and response measurements (weight loss), the design of experiments and analysis of variance (ANOVA) is used. The control variables such as normal loads (5, 10, 15, and 20 N), velocity (1,2,3 and 4 m/s), and sliding distance (200, 300, 400, and 500 m) are selected for the research. It was observed that 0.5wt.% GNP-filled carbon fiber/epoxy composite shows higher tensile and flexural strength than another composite. It has been discovered that adding GNP reduces the wear in terms of weight loss. Scanning electron microscopy (SEM) was used to examine composites' worn surfaces. The analysis concluded that experimental results are closer to optimum results.

“…For example, Ogbonna, V.E. emphasized [ 21 ] some issues of interfacial adhesion and surface degradation, which affect their mechanical properties and abrasive wear resistance in tribological applications. The following are considered fillers for such PI-based nanocomposites: CNTs, GN, graphene oxide (GO), boron nitride (BN), MoS 2 , silica (SiO 2 ), titania (TiO 2 ), alumina (Al 2 O 3 ), CFs, aramid fibers (AFs), GF, zinc dioxide (ZnO 2 ), zirconium dioxide (ZrO 2 ), silicon nitride (Si 2 N 4 ), and carbon nitride (C 3 N 4 ).…”

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.

“…It has excellent chemical, thermal, and mechanical properties [ 1 ]. In recent years, a lot of advancements have been made in developing polyimide nanocomposites, because these composites exhibit high strength, better thermal stability, light weight, corrosion resistance, good interfacial bonding, solvent resistance, and antiwear [ 2 ]. In developing new polyimide nanocomposites, the focus is on the improvement in thermo-oxidative stability, resistance to microcracking, and the development of a toughened system [ 3 ].…”

Polyimide matrix nanocomposites have gained more attention in recent years due to their high thermal stability, good interfacial bonding, light weight, and good wear resistance and corrosion, factors that make them find great applications in the field of aerospace and advanced equipment. Many advancements have been made in improving the thermal, mechanical, and wear properties of polyimide nanocomposites. The use of nanofillers such as carbon nanotubes, graphene, graphene oxide, clay, and alumina has been studied. Some challenges with nanofillers are dispersion in the polymer matrix and interfacial adhesion; this has led to surface modification of the fillers. In this study, the interaction between clay and graphene to enhance the thermal and thermal-oxidative stability of a nanocomposite was studied. A polyimide/graphene nanocomposite containing ~12.48 vol.% graphene was used as the base nanocomposite, into which varying amounts of clay were added (0.45–9 vol.% clay). Thermogravimetric studies of the nitrogen and air atmospheres showed an improvement in thermal decomposition temperature by up to 50 °C. The presence of both fillers leads to increased restriction in the mobility of polymer chains, and thus assists in char formation. It was observed that the presence of clay led to higher decomposition temperatures of the char formed in air atmosphere (up to 80 °C higher). This led to the conclusion that clay interacts with graphene in a synergistic manner, hence improving the overall stability of the polyimide/graphene/clay nanocomposites.
