“…The reported properties were basically on tribo-system. More so, past researches has showed that the thermal resistance of PI improves by the incorporation of inorganic fillers into its matrix network, which has attributed to its better thermal stability, 18,86,88,101,116 for instance, a closer look at Figure 13 revealed such an improvement although, the review study emphasizes more on tribological system. Hence, for future enhancement of PI properties, adopting inorganic fillers as reinforcing phase material into its matrix with suitable structure design remain a way forward.…”

“…121 In considering the cost effectiveness and recent observed improved interfacial bonding of polymer composites processed using spark plasma sintering (SPS) technique, the poor interfacial bonding interaction of polyimide nanocomposites, which has affected its mechanical and tribological performance can be improved even without much surface modification of the reinforcement particulates as mostly performed during in situ polymerization, sol gel method and so on using SPS development system design. Besides, research has showed that SPS offers rapid densification with negligible grain growth, better interfacial bonding of the matrix and reinforcing phases, it required short dwell time to achieve 116 effective homogeneity in composite, it is cost effective and energy efficient technique. 68,122,123 And researchers like Schwertz et al, 122 Adesina et al, 124 Adesina et al, 125 Tanaka et al 10 have reported widely on the consolidation of polymers and polymer composites using SPS technique as can been seen in Figure 14 126 and Figure 15, 10 though optimizing the PI nanocomposites properties using SPS have rarely been reported.…”

In recent years, advancements on improving the mechanical and tribological properties of polyimide nanocomposites have remarkably increased, owing to the fact that polyimide nanocomposites exhibits lightweight, high strength, thermal stability as well as anti-wear and solvent resistance. The polyimide nanocomposites are described as material of polyimide matrix reinforced with certain volume or weight percent concentration of nanofillers. Researchers have demonstrated the importance of thermoplastic polyimide nanocomposites in mechanical, thermal, and tribological applications. However, the nanocomposites are reportedly facing interfacial adhesion issues and surface properties degradation, which have affected their mechanical, friction, and abrasive wear resistance for tribological applications. Although, much advancements on improving the mechanical, thermal, and wear resistance properties of polyimide nanocomposites has been reported. However, this review summarizes the effects of nanofillers, such as carbon nanotubes (CNTs), graphene (GN), graphene oxide (GO), boron nitride (BN), molybdenum disulfide (MoS2), silica (SiO2), titania (TiO2), alumina (Al2O3), carbon fibres (CF), aramid fibre (AF), glass fibre (GF), zinc dioxide (ZnO2), zirconium dioxide (ZrO2), silicon nitride (Si2N4), and carbon nitride (C3N4) on the mechanical, thermal, and wear properties of polyimide nanocomposites for tribological applications. The authors concluded the review study with advancement, challenges and suggestions for future improvement of polyimide nanocomposites as friction component material. Thus, the review offers an insight into the improvement and selection of polyimide nanocomposites material for mechanical, thermal, and tribological applications. More so, the review will also give away for further research.

Purpose Previously, the effect of pore-forming agents on the properties of pore size and morphology was studied. In this paper, we determine the optimal combination of parameters by tensile strength and perform tribological tests with optimal combination of parameters. Design/methodology/approach In this paper, porous polyimide (PI) materials were fabricated using vacuum hot molding technology. The orthogonal experiment was designed to test the mechanical properties of porous PI materials with the process parameters and the content of pore-forming agent as the changing factors. The porous PI oil-bearing materials were obtained by vacuum immersion, and tribological test were carried out. Findings The results showed that porous PI oil-bearing materials are suitable for low-speed and low-load conditions. The actual value of the friction coefficient basically match with the theoretical value of the regression analysis, and the errors of the friction coefficient are within 10% and 3%, respectively, which proves that the method used in the study is feasible for the friction coefficient prediction. Originality/value In this paper, we have produced a new porous oil-bearing material with good tribological properties. This study can effectively predict the friction coefficient of PI porous material.

“…In addition to the type of polymeric matrix being used, the tribological performance of engineering plastics is greatly affected by the filler type, dispersion rate, and matrix-filler compatibility. 8 Various micro-scale lubrication fillers such as polytetrafluoroethylene (PTFE), 9 aramid fibers, 10 graphite, 11 and Si 3 N 4, 12 have been used to reduce the friction coefficient and wear rate of PI composites. However, in most cases, the mass/volume content of these fillers in the composites needs to exceed 10% to achieve acceptable friction-reducing and anti-wear effects; moreover, the mechanical properties of the composites may be significantly affected by the increasing quantity of large-scale fillers.…”

In this study, nanographite (NG), as a lubricant additive, and polyimide (PI) were used to fabricate NG/PI composites via a hot compression molding process. The tribological properties of the NG/PI composites with different NG mass contents (0-10 wt%) were tested using a reciprocating ball-on-disc contact tribometer matched with a GCr15 rubbing pair. The thermal stability, surface hardness, and compression strength of the composites were discussed. The results revealed that a small quantity of nanofillers greatly reduced the friction coefficient and increased the wear resistance of the NG/PI composites. Despite a minor decrease in mechanical performance, the composite with 5 wt% of NG filler exhibited improved tribological properties; it showed a 55.63% reduction in the friction coefficient and a reduction of 97.39% in the wear rate compared with neat PI. Moreover, an increase in the glass transition temperature (T g ) of the NG/PI composites indicated the enhancement of their thermal stability and wear resistance. Scanning electron microscopy (SEM) analyses showed that the main wear mechanism of the composites was fatigue wear. These findings suggest that the 5 wt% NG/PI composite could be a significant contribution to the field of tribological engineering plastics.
