“…5(a), the friction coefficient of fabric composites increases with the number of self-assembly cycles, until a limiting point after which it decrease. Like in previous work [27], the addition of GO does not reduce the friction coefficient of the hybrid fabric composite, while obviously improving the wear resistance. The LbL self-assembly increased the friction coefficient from 0.0778 to 0.137, whereas the wear rate was significantly reduced from 1.231 to 0.551.…”

Fabric composites are widely applied as self-lubricating liner for radial spherical plain bearings owing to their excellent mechanical and tribological properties. Nevertheless, the poor interfacial strength between fibers and the resin matrix limits the performance of composites utilized as tribo-materials. To overcome this drawback, a mild layer-by-layer (LbL) self-assembly method was successfully used to construct hybrid fabric composites in the present work. In addition, this investigation addressed the effect of self-assembly cycles on the friction and wear behaviors of hybrid fabric composites under dry sliding condition. The results demonstrate that fabric composites with three or more self-assembly cycles have significantly enhanced surface activities and anti-wear performances. The results obtained in this work can provide guidance in the preparation of selflubricating liner composites and highlight how the LbL self-assembly techniques could influence the properties of hybrid fabric composites.

Epoxy resin (EP) has received extensive attention in the field of mechanical engineering due to its outstanding physical mechanical performance and chemical stability. However, relatively weak thermal and abrasion properties seriously limit its application in motion conditions. Here, we report copper-graphene nanohybrids (Cu-G) prepared by a space-confined thermal disintegration method as promising materials for improving the thermal and tribological properties of epoxy composites. Impressively, the thermal conductivity and stability properties of EP/Cu-G composites present obvious enhancements compared to pure EP. Meanwhile, the tensile strength and elongation at break of EP/Cu-G are increased by 8.0% and 7.5% compared to those of pure EP. In addition, sliding test results reveal that the wear rate of EP/Cu-G composites show a 66.7% decline, which can be ascribed to the synergistic enhancement effects between graphene and Cu.

“…With bringing different fillers superiors into full play, nano hybrids material had aroused many attentions. Yuan et.al chemically grafted GO onto Nomex/PTFE composites, and their results show that, compared with pristine hybrid-fabric composite, the tensile and the interfacial bonding strength of the composites were significantly enhanced by the graft of GO (Yuan et al, 2018). Mi et.al prepared ZrO 2 /GO multi-layered nanocomposite lubricating film and the result show that the as-constructed film exhibited outstanding tribological performance and mechanical property (Mi et al, 2014).…”

Purpose The purpose of this paper is to investigate the fretting wear performance of ultra-high-molecular-weight-polyethene (UHMWPE) with addition of GO and SiO2. Design/methodology/approach In this study, GO were synthesized and SiO2 nanoparticles were grafted onto GO. The effect of nanofiller on fretting wear performance of UHMWPE was investigated. Findings The results indicated that GO was successfully synthesized and SiO2 nanoparticles successfully grafted onto GO. Incorporation of GS was beneficial for the reduction in friction and the improvement in wear resistance of UHMWPE. GO was beneficial for reducing friction coefficient, while SiO2 was good for improving wear resistance. There existed a tribological synergistic effect between GO nanosheet and SiO2 nanoparticles. Research limitations/implications The hybrids of GS were promising nanofiller for improving the fretting wear performance of UHMWPE. Originality/value The main originality of the research is to reveal the effect of GO and SiO2 nanoparticles on fretting behavior of UHMWPE. The result indicated hybrids of GS were promising nanofiller for improving the fretting wear performance of UHMWPE.
